Gigabyte GA-P35-DQ6 crashing games?

I've been having very strange crashes when trying to play games on my system. Randomly the game will freeze and my LCD monitor will claim that it no longer has a video signal. I'll hear sound thrashing for a few minutes and then the computer will reset itself. I'm using the 163.75 beta drivers. I've been having a hell of a time with this. I'm even RMA'ing my memory. System specs should be part of my signature. Any help or ideas is greatly appreciated.

What CPU do you have?

I have a DQ6 & have been unable to get either 2gb or 4gb in dual channel working.
Mine will freeze in games too. The only way I got it to work perfectly was running 2GB in single channel(memory in different colored slots)

Didn't you run a program like memtest86+ to see if it was the Ram? Case heat can cause a crash like your describing, after my OC my case got really hot inside and it crashed and then restarted after it cooled down. Theres soo many things it could be, did you get any blue screens and if so what error code did you get?

Uhh I never said you that did. Have another look at my post, "my OC". Just because you haven't OC'ed you PC doesn't mean that it can't get hot in your case. That looping sound is most likely your sound card drivers not playing nice with Vista. You never ansered my question, did you get a blue screen?

If you have to enable Vsync to fix the problem for any game then the problem is with your graphics card or its drivers. Are you running any sort of monitor utility like Magic Tune, these programs have been know to interfear with any video card drivers?

I have heard from many that Vista Ultimate 64 is not very friendly with any video card drivers designed for a 32bit OS. Most games are 32bit, except the 64bit version of Crysis 64.

Actually Crysis 64 bit demo won't run... also I get a signal drop in that game unless I force vsync with Nvidia's drivers. Very very odd...

Hmm... my frequency is only 60hz.. Not sure what could be increasing the monitor frequency without forcing vsync...

You didn't adjust your PCI-E frequency in bios did you? If you did most people have problems above 120Mhz, mine is locked at 100MHz.

I have a very similar problem to yours. I've usually powered down pretty quickly, for fear it's a hardware issue, but when I leave it for awhile trying to break out of the process, the graphics go haywire. Never had the computer shut itself down. I do get the looping sound though - this is fairly common in my experience when a game crashes or the computer lags out.

I'm using a GigaByte GA-M57SLI-S4, with one PNY 8600 GT, thats about the only similarities between my system and yours. I'm using 32bit Windows XP, and an AMD-based system.

Once again, error in nvldkkm.sys was returned on a blue screen. This time while playing Jericho. Really frustrating... not sure what to do...

I don't think so... I'd have to check with PNY...

The warranty is five years. I'm going to e-mail them tomorrow. I've tried setting the PCI-e frequency to 100mhz manually. I didn't have time to test it but upon starting my computer today I got a BSOD I couldn't record, it then restarted and seems to be okay... We'll see what happens...

Thought I was in the clear after trying to underclock the 8800gtx... however that's not the case. I'm really angry about all this... I'm starting to be turned off of pc gaming.

Lol

System is only 50 degrees Celcius. Maybe 60 when revved up. Still doesn't seem terrible. I made a mistake, it happens.

I think it's the video card. It's being reported at 80C which seems ridiculous. How can it be reporting at such high amounts of heat? I don't understand it. It cannot possibly be that hot and still work at all...

When I say my graphics card is 68C I mean the GPU core itself, not the amient temperature. My ambient temperature right now is 26C or 78.8F and my CPU is 27C, and your saying your ambient temperature is 50C/60C revved up. Do you know how hot 50-60 degrees C is? So your 80C temperature for your GPU isn't hard to believe. With all the data you have given us things are now starting to make sence. 60C Celsius = 140 degrees Fahrenheit and for your GPU 80C = 176F, thats hotter than any desert on planet earth!

What case do you have? I would think that the Antec 900 would solve all your heat problems, it has 1-2 120mm fans in front and a 140mm on top in back plus one 120mm in back side.

Where are you getting all your temps, Speed Fan? You say you made a mistake, are you saying that you temperature program made a mistake? What is your amient temperature?

Give me all you temps that you have, so I can have a look at them.

Now let me see you temps using Orthos blend test, I don't know how your running your quad @ 1.1 Vcore thats not stock Vcore is it?. If you are you can't undervolt you proceeser and expect to have a stable system. I must see you temps under load.

The program Orthos stress tests your computer for stability and if a computer isn't stable the most likely thing that will happen is you computer crashes when you start to stress it like playing a game or running many different programs at once.

Heres a link to download Orthos and when you run it you want to select blend = stress CPU & RAM and let it run for at least 8-10 hours. Also so that you can surf the internet set priority to = 8. If your PC crashes durring Orthos then we know what your peoblem is then we proceed from there. I have right now 14 hours Orthos stable on my overclock so that means that my system is stable after 12 hours of being stressed without any errors.

I'm surprised nobody has asked about your power supply (unless I missed it, kinda skipped through thread due to lack of time).

I have a ThermalTake ToughPower 850W
