Computer just stops while gaming

June 1, 2009 at 21:40:45
Specs: Windows Vista
I built the system myself and it is stable 99% of the time. While playing online games, sometimes the computer just comes to a complete stop, monitor goes black and I'm done. After this happens, the chasis fans, cpu fan and graphics card fan are all still running. (Graphics card is ATI 4870...which as far as Ive seen online, knowingly runs hot compared to other cards) I combat this with high fan speeds. Anyway, the only way I can restart is to push the power button off and on. Any thoughts on what might be causing this sudden crash?

that means your graphics card not completely compatible with your motherboard. try find driver updates.

i'd look to overheating as a more likely explanation than incompatible, because it sounds like the games LAUNCH just fine, and even play for a bit before the system locks up.

do you have any temp monitoring software? have you checked BIOS temps after a crash? Can you get the PC to crash with Prime95, or is it just games? (that would suggest the CPU or RAM being the problem, instead of the graphics card). If you take the side off of the case, can you game longer before the problem reoccurs?

Make sure your case fans are working together to increase total airflow through the case, and not competing with one another. Also give the graphics card a few shots of compressed air, although you said this system is freshly built so i doubt it's just a dust problem.

Also make sure you are running the minimum of other programs. I had this problem until I cut back on running services and start-up devices. msconfig

Download a program called RealTemp, and run it, then tell us what the temperature on each core is.

Also, update your graphics card drivers:
ATi Drivers

Go into the Catalyst Control Center (right click your desktop, and select the CCC), and up the fan speed to 80%, then see if it does it.

Make sure the rear of the computer is clear of obstructions also, heat might not be able to escape.

Disregard the second post, he's talking B.S.
