Random Game freezes...is it my PSU?

No one can tell you that the problem is your PSU, because there is no way we can know for sure.

Does your computer lock when it's hot in the room?

Did you update your motherboard drivers including your sound card drivers?

Why do you have to have a Thermaltake? There are many better brands.

I have a 600w thermaltake psu for a XFX8600gt videocard and M2N32-sli mobo setup and have no issues so far (1+year old system)


If u overclocked the system reset the bios settings to defualt

I would also check the voltages of your stuff e.g make sure that your ram and cpu are running in the recomended voltage range. if they are set to auto i would configure them manually then use prime95 to test the systems stability

edit
as Proximon said it could be an overheating issue. Play the games with an open case to see if it freezes. Check your temps also using speedfan or everest and post them

As you have problems one day and not the next i would be looking first at checking your temperatures. A hot day outside and a box in a not too well ventilated room can raise your temps by 10-15 degrees no problem.So when you are gaming and your machine is going flat out a cool background ambient temp may be enoughto keep your machine from keeling over, game on a hot day and that's enough to take it over the edge.Load 'Everest' a system diagnostic utility, and set it to display your cpu/graphics temps on toolbar , then do a bit of 'monitoring. You may be suprised the difference before/aft gaming. Then compare what you run at and other people's same cpu and 9800gtx run at. That's where to start before you go throwing money at new power supplies - though you may go down that route after you have tried other options Proximon states. Another thing you can do,if you do have a day when when m/c keep falling over just take side of your box off and see if that stops it.

15-16 amps is a little light on the 12v rails. Check your temps, also, check to see how hot the air is without using 3D, run 2D for awhile, then feel the temps from your psu fan, then run 3D and see how much hotter it gets. It will be hotter, but if the psu is heating because of not enough power, itll be real hot. What else do you have on your system? Sound cards, extra fans, dvd writers, HDDs, modem etc. All those add up, its either heat or power, as both take time to build up. Just remember, low power from the psu causes heat

why has no one suggested a virus? i just helped a friend yesterday who had random freezes while counter striking and sometimes when just msning... i suggested virus and it turns out i was correct.

hi thx for replies
i dont think its heat cause sometimes it happens 5min into a gaming session also itried using the evga precision tool and pushing fan speed up to 100% but that didnt help. also it doesnt seem to to change wether im playing with the air conditioning on (in wich case the room becomes freezing) or off. i will download everest and get back to u with the results.

other than the hardware i previously mentioned i have 1 HDD and 1 dvd writer and the fan my case came with (case is a thermaltake soprano RS) sound card and network card are the ones built into the mobo.

concerning the mobo and soundcard drivers i previously had an asus p5kdeluxe wich is now dead due to a botched bios update. but i remember that i had updated everything on that board and the freezing problem still persisted. on this board i havnt updated the drivers but ill try that.

i dont overclock my machine and ive never even entered the bios so im assuming everything is on default. honestly im reluctant to mess with voltages and stuff after the tragic loss of my first mobo.

its not a virus cause it happens on fresh formats that havnt even been connected to the internet

i kinda have to go for thermaltake cause they are the only readily available brand were i live + i think i can swap in the psu i currently have for a better one and pay the difference.

if all else fails would the thermaltake tough power 750W be good enough for me?

thx for being patient guys

Yes, do updates.

Don't assume "freezing problems" have the same source. Maybe they do, but they can be identical and yet caused by many different issues.

The 750W TP is actually a well reviewed PSU. Just don't assume any Thermaltake is good  

You still have not told us you temps, what are they?
Track you temps for a few days, CPU, Video, motherboard and ambient.
Especially get your temps when things hang.

These are my current temps, pc has been on for about 10hrs straight but i havnt done any gaming all day

and these are the values from evga precision:

GPU temp: 60 c

Shader clock: 1674 Mhz
Memory clock: 1102 Mhz
Fan speed: 41

ive noticed that 60 c is the temp the vga maintains itself at if i dont mess with the fan speed.

Vcore looks okay for stock. If that is idle temp on the cpu (48C) which is the tcase sensor, you either have very warm ambient temps, constricted airflow, or the HSF isn't on correctly, especially if its the stock HSF.

But depending on the game the CPU usage may not get too high, unless your running games at a low resolution. My Q6600 idles (tcase) 29-35C depending on the ambient temp, and when it's idle its at 2.4ghz, under load its at 3.2ghz.

So at stock, 1.6ghz idle the temps should be lil lower then mine with cool ambient temps.

after a 1 hr wow gaming session, didnt freeze.

The CPU temps seem a bit warm, but not so much as to cause problems. Temp #3 and 4 look to be too warm, even though I don't know what they are. If those are hard drives, you need some cooling on them.

I don't see that a memtest has been run. That should happen as well, preferably overnight.

If you look in the forums there are loads of threads on problems with the 9800gtx gpu fan being stuck on 35% regardless of temperature (driver related)

(use COD4 rather than WOW to stress your card)

just a random thought here,, ...:is your hsf properly mounted and firmly and did you use a good tim [thermal interface material] like AS5,and was it spread razor thin,,after all it's primary purpose is mainly to fill the micro holes between the top of your cpu and the bottom of the heat sink,those oem intel fans can and are less than trustworthy,,check out ,,, frostytech.com,,,,maybe you will find something more reliable.......
