hello, i have core 2 duo 8400, asus p5kc, gf 8800 gts (gigabyte), a-data 2gb ram.i bought pc just few days ago and played games like WoW or neverwinternights 2.however, today my computer started to freeze when i am in game (but in windows do not freeze, or when i am playing counter-strike,...).it seems it started to freeze only when i am running some new games, which need a lot of performance.i havent done any overclocking or any new updates, anything.just started pc today and the games started to freeze.i can not do alt+tab, nothing...simply reset, go back to game, play 5 minutes and all over again.do you have any idea?

i have new forceware 169, installed chipeset p35 etc. please, help me:(

what kinda power supply do you have? Did you buy it separately, or did it come with the case? Post the power supply name (and everything you can find on it for that matter) and we'll go from there.

I had a similar problem some weeks ago and i changed my power supply and got a new fan for my cpu, its been almost 2 and a half weeks and no freezing and i play crysis and cod4. Another thing you can try is to geta program like drivercleaner pro and uninstall your chipset and video card drivers and reinstall them.

It could be either power supply or your ram. I've had many hard lock freezes in my past experiences. It sounds like it's either of these two.

What's your PSU? Brand/model? Then we can help you get this problem fixed.

Once we find out what your PSU Make/Model is, we can advise you on what to do.

That could be why. I'd recommend getting at least a 500W PSU, but to be safe, get a 550W+ quality PSU from companies like Corsair.

but i bought it on monday and everything was ok, i played nwn2 like 5 hours and it worked well.the freezes started today...or it doesnt matter?Oo
February 10, 2008 6:06:04 PM

I've never heard of it...The Eurocase 5410 is a case right? and the PSU came with it? If that's the case it's going to be a cheap **** psu.

Personally, I'd replace that PSU asap with something on the tiered CPU list.

If cash is an issue, you can nab something like this.

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

great amperages on the 12 rail, and a tier 3 psu to boot. If you can nab something even better on the tier 2/1 list. Go for it...Just base it off where you live and what prices you can get. I found it very difficult to get any info on that eurocase 5410, all the sites were foreign, so you're probably not in the states?

Also head over to http://www.memtest.org/ . Download a prebuilt iso or the floppy version and run it, just change your boot priority to your cd rom drive via the bios. Let it run..

chances are, it's your PSU..You have some power hardware in your rig, and you NEVER want to couple that with a cheap **** PSU...If that PSU blows (from the cheap components), it can take your entire rig with it, not a worthy investment. Try to nab a new psu, it should fix your problems, but if it is your memory, run the memtest app I spoke of, and let it run for a few passes to see if your memory is reporting errors.

First, run memtest to see if your ram is good. Then run Prime95 blend test for at least 8hours to check if your ram is stable.

If it passes all of the above, then grab a copy of Rivatuner. Then underclock your vidcard like crazy. If the problem goes away, it's your PSU.
February 10, 2008 6:17:40 PM

i was told it could be something with fan, value set to 29% (kind of a "bug" with 8800).and that i need to set it to 50-60%.is this right?

Heat could also be the issue. Grab Rivatuner and increase the fan speeds.

450W is enough, but cheap PSUs doesn't give out all 450W. Maybe yours is only giving out 400W max.
February 10, 2008 6:25:12 PM

It doesn't matter really if you are told. Considering that you stated it was a eurocase psu, it came with your case. Almost all PSU's that come with cases are crap...They are very low quality and not worth the money. Your best bet, would be to nab a new psu. But first, run memtest, and follow what everyone has advised. If it's not your PSU...that's great..But that still doesn't change the fact it's not a quality PSU. When it comes to a powersupply, watts aren't the most important thing, It's a combination of watts, amperages, and quality. You could go about and buy a 200 dollar PSU that has 1000 watts and 90 amps on the 12 rail, but if it doesn't use quality parts, it's still a crappy psu.

Please don't take any offense to this, just trying to inform you the differences in the PSU world. If you follow that Tiered list I posted in my previous post, it will guide you to a quality unit. But first run memtest, and see if your memory is reporting errors, and bump up the fanspped via rivatuner as evilonigiri stated. If the memory reports no errors, and the increase in fan speed doesn't help, then it's 100% your PSU.

He is right. Most case supplied PSU's are crap. The best ones I have come across are the ones that come with Thermaltakes cases which are their own PSU's. They are pretty nice or at least my old 420w PSU that came with my XaserIII lasted me 5 years. I just replaced it for the hell of it with a 550w Rosewill PSU.
February 10, 2008 6:51:43 PM

and how to check that fan speed through rivatuner?and how to increase?i went to "power user" and do not know what next.i can go nvidia fan with binaryfanspeedcontrol and minfanspeedlimit, or current device with fan speed0-2, or just nvidia fan etc. Oo

oh, i followed http://www.vaguesoft.com/users/dwood/blog/tutorials/riv... and made it until AUTOMATIC FAN CONTROL and saw a strage thing: core clock shared domain (it is until 1500)-that thing i have at 1674 with yellow triangle with "!".does it mean anything?

No, that means it's off the charts. Just change the upper limit around.

As for your 8800GTS 512MB, did you enable support by adding "600h" to "G92=" in the config?
February 10, 2008 7:24:14 PM

yy, i added it and follow tutorial.now, i can see core temperatue 58 degrees.too much, isnt it?
February 10, 2008 7:28:41 PM

GPU temperatures can be a LOT higher than CPU's depending on the architecture of the gpu. So don't worry about it too much. I don't have an 8800 GT, so not sure, but i do know that people have had overheating issues with the single slot 8800 GT design..So I'd guess those suckers can get pretty hot....

Did you run memtest yet? You really should run memtest to see if it errors. Also, just slap the fan speed up to 100%...leave it as is for about 20-30 minutes to cool, than game on it and see if the pc freezes.

Make sure you do both! Memtest and this fan issue...But honestly, I'd bet my money on it being the PSU.

Jimmy: You just replaced it with a rosewill?...You do know that rosewill is one of these psu's I'm also talking about, tier 5 psu that should NOT be purchased.
February 10, 2008 7:39:38 PM

As it's new, just take it back and tell them to fix it! :)

February 10, 2008 7:56:46 PM

If it worked fine and acted up it could be PSU or RAM. I would try a system restore back to a day you know it was working. Maybe a driver or software install is causing problems. Anyhow I would check that 1st, then memtest96 for 6 hours, then try a new PSU.
February 10, 2008 7:59:08 PM

i set fan to 60%, played for about 20 minutes and it freezes.however, i played much longer:D  and set it to 100%...i can do it, but even if it works, i do not want to listen to that sound! and no, i have not made a memtest, i do not know to do that...i will see servis tommorow:) 

and about that PSU...i can buy only this, so please help me to chose:

Very difficult to make a choice basing on the language barrier. But here..

http://www.datacomp.sk/default.asp?cls=stoitem&stiid=12...

IF you can spend the extra cash, get this instead.

http://www.datacomp.sk/default.asp?cls=stoitem&stiid=15...

This one is modular, great tier 2 power supply, I actually have it in a rig next to me that I've built for a family friend. The modular aspect is also great for improving airflow.

Hope this helps. BUT, run memtest first!

Download this..

http://www.memtest.org/download/2.00/memtest86+-2.00.is...

Unzip it, inside should be an iso. Use burning software to burn the iso...Make sure you burn the IMAGE...don't just burn it to a data compilation, you need to burn it as a Iso/Image. Once done, restart your pc, get into your bios (pay attention to the screen as it boots, most boards are "del" for bios entry). Once in, go to your boot priority section, and change the boot order to have your cd rom drive first. Than save and exit your bios...Once the pc restarts and goes past post, it will boot into the cd (if the cd is in the drive), memtest will run, let it run for 4-6 hours, pay attention to the "passes" and "errors" section. If it errors, you know you have faulty memory which needs to be replaced.

Hope this helps...
February 10, 2008 8:19:08 PM

really thanks:)  ok, but do you think my new a-data could be errorous after 5 days of use?Oo

and, do you think is worthy to spend some more money on that second PSU?
February 10, 2008 8:29:07 PM

Regarding your questions, ram can work fine even when faulty. But it's not a good thing to do. It can lead to bad data being outputted by the ram which eventually can lead to a needed format and OS re-install. You don't want bad ram, also, bad ram is known to cause errors, from blue screen to computer lock ups. I've had plenty of experiences with bad ram in the past. You don't want bad modules, RMA or return them if they are faulty, all you gotta do is run memtest to find out.

Requiring the power supplies, the Corsair 520HX uses higher quality components than that fortron I linked. Overall a much better Power supply in terms of quality and stability. The Fortron one is hard to get info on, but it falls under the product lineup of the tiered listings....IF you have the extra cash to get the HX, get it, you won't be disappointed. As I sated before, the PSU is the most vital part in a system, what good is all that hardware if you don't have a quality PSU to ensure it runs smoothly? As well as not die out and take your computer with it...If you have the extra cash, nab the HX, if you're on a budget, the fortron will do just fine.

oki, really thanks for all:) 
February 10, 2008 8:44:12 PM

Anytime ^_^, keep us posted, and will help out with any issues or problems you come across. Make sure you run memtest first though, I can't stress that enough. Best to find out if your memory is faulty or not, that way you at least know to return your ram for replacements.
February 11, 2008 3:08:15 AM

so i ran test for 6 hours and it found over 27 000 000 errors with pass 1.it is bad, isnt it?
February 11, 2008 3:15:33 AM

ROFL...Yes. Make sure you are running your sticks at the specified memory though in terms of voltage and timings. Set the timings manually, and the voltage. Then run memtest again, if these sticks are already at spec voltage and timings, than you know they are the culprit at hand. Or it STILL could be the power supply with not enough juice..But I doubt that considering you are running fine in windows. If you have another computer that's compatible. Try to take this memory and pop it into that machine (Unplug the rig first for like 20 seconds, than replace the sticks, make sure to touch the metal casing at the bottom to disperse any static electricity (static + computer = death), than run memtest on that as well to see if it errors. If you don't have another machine, don't worry, just use a friends, or just go ahead and replace the memory. Only reason I recommend doing this, is to make sure it's not the power supply, but it's unlikely considering the amount of errors and nature of the freezing.

But you pretty much found the culprit, replace the sticks, and you should be fine, make sure to run memtest on the new sticks as well. Personally, REPLACE that psu....You want a quality unit in your rig, and not a low quality unit that could break every piece of hardware in your machine if it gives out. Not worthy at all considering how much your components cost.

That's pretty much it, replace ram through RMA or return them, getting a new psu is HEAVILY recommended to make sure your rig is stable, and lives a long time. Welcome to the world of understanding hardware ^_^..I bet it was a bit adventurous for you? Eh? =P
February 11, 2008 3:20:33 AM

yes, since that machine cost me a fortune!:D  i will replace PSU in few weeks and will take PC to servis today.they will try replace it and stuff, i do not want to harm anything.my old pc runs ddr400 i think, so i can not replace it.most of those errors was somthing with "921mb" (like 90% of them).
February 11, 2008 3:25:36 AM

anyhow, i have had problems with "monitor" since i bought new pc, like i started win and screen freezed with some strange errors on desktop(big squares with odd colours etc.).i thought it could be something with generator(in monitor) but now i think, it could be cause by this errors with ram...am i right?

and at last, but not the least-when i start pc and i check temperatures, it gets me an alert, my mainboard (asus p5kc) runs at 50 degrees.Oo
February 11, 2008 3:34:32 AM

You mean check the temps through the Bios? or windows?

Regarding the the big squares and odd colors, that is a bit odd. It could be a faulty video card, or the fact that this memory has been extremely faulty has led to a corrupted installation of windows (which would be best if you formatted and start from scratch). Could go either way...If your other computer is a PCI-E based board, throw in your current 8800 GTS and play a title or two, see if it freezes up, that would be the best way to find out if your psu is also to blame. I really would recommend doing this though, since you have a very low quality psu, there's a chance it can also be a factor of the freezes and memory errors, or even the main factor for the memory errors if it's not giving enough juice for your rig. But yea, since you're replacing the PSU, nothing to worry about, just replace the memory as well, and all your problems should go away. If it still freezes or locks up after both are replaced, your video card also has an issue at hand =P...I know it may sound extremely depressing, but having problems every now and then with new rigs is quite common. I had to RMA the memory for this rig I'm on right now as soon as I got it, one stick was faulty, my second set came with no problems what so ever.

Keep your chin up ^_^, you're almost there, soon you'll be gaming with no freeze ups what so ever ^_^.
February 11, 2008 3:38:59 AM

soon (in one week) i am back to university:D  will take pc to servis today and tell them to test memory, psu and graphic card.hope, they will find the reason and it wont cost me much:) 
February 11, 2008 3:43:14 AM

Indeed...Make sure you tell them that memtest reported errors, if the guys at least know how to troubleshoot a computer for faulty hardware, they'll know instantly to replace the ram, also, buy that PSU as soon as you go in and replace it out. Once you get that rig in your hands, run memtest when you get home, if you get no errors, you're good to go. Any further problems would mean a video card issue..But I doubt that will happen, it's pretty much a ram problem, but replacing the PSU is a wise move to ensure stability/quality.
February 11, 2008 3:52:45 AM

Try using the NVIDIA controll panel to underclock your card by 10 or so on the Core, and Mem, then up the fan to 40% or so. (I have the same issue with my BFG 8800 GTS[G92])
February 11, 2008 3:55:37 AM

underlock?where exactly please?
February 11, 2008 3:59:41 AM

Underclocking means turning down the gpu core and memory clocks. Basically exactly as it sounds, running the hardware slower than it's specified speeds. It should be in your nvidia control panel, but since I don't have a 8800 Gt, don't know where, you might need to download Riva tuner to do so. Unless the control panel has it built in. Someone else can better assist you on this segment =P.
February 12, 2008 3:26:12 PM

ok, my pc is back from servis.it was my graphic card, which was faulty...now, it works well:) 
February 12, 2008 6:50:56 PM

Maybe but I doubt it. Ram or PSU most likely. They probably just said it was the card to charge you tons more then the other 2 problems.
