Computer instability problem.

[djduma]

So, if I understand it correctly the flashing/updating of the videocard's bios was meant to fix the instability issues, such as shutting down of the PC in the middle of a game session, right?

Anyway, can you please fill in the system specs in your sig., e.g. the exact motherboard (brand and model), cpu cooler, ram configuration (such as how many ram modules and the size of each of them, including timing, Vmem etc.), other PC components like pci or pci-e expansion cards etc..

As far as I can say is that over 84 degrees Celsius may have triggered the processor to throttle and computer to shut down. Anyway, does anyone know the TJ Max of the Core i7 920? I couldn't find it, but found an interesting article: http://www.pugetsystems.com/blog/2009/02/26/intel-core-i7-temperatures/

Replace the cpu-cooler with a better one, e.g. one with heatpipes or direct touch heatpipes, and make sure there's a good airflow in the PC case by mounting fans in the PC case (e.g. one in front of the case and one in the rear).

you mean my system details right?
here are some screen shots & links of my hardware

thanx for the article mate

ya im try to have good airflow thats why i replace my casing to this more fans than my older casing....

do you think that processor heat can restart the PC while im playing a game? hmm its a good point. im using normal I7 processor's fan...

98c

looks 85 ok.

I see the PSU ok brand. but modular. I suggest first check the cable connections, may swap the GPU power cable .
Its a single rail 12v. but I would still try from diff connection each power to the GPU.
try thet.

im sry i didn't get that? you mean swap the power connectors of the VGA card?

^THIS^

Run some tests and give some screen shots of the results.

Are you over-clocking the card or anything else?
Do you have good airflow in that case?
What are your ambient temps?
Did it always do this or just recently?
Have you made any changes to your system?

Try using CCC overdrive and throttle the video memory back 15 to 25 Mhz... then try your games.
Good-luck there.

can you give me a softwares to test (without overclocking software)
nooo i didn't over clock...
hmm yeah i think so... in normal mood (without doing high performance thing eg: 3D animation or gaming) its temp around 45-55.
actually sometimes game runs perfectly after few minits it does, but sometimes it does several times....
what do you mean the changes? i have install the power supply and the casing.

I guess thet PSU got extra cables, change thet from GPU to PSU.
other thing. ifd the GPU power cables comming from the same cable from PSU, try 2 cable 2 connection from PSU to thet two GPU power connector.

I just try rule out connection problems to thet GPU.
My guess is, 75w from PCIe 75w from one connection 75w from second, if one of them loose, may cause same problems like you have. Because under load the GPU dont get inaf power.
