My PC will just shutdown when gaming (no errors).
motherboard - ASRock ALiveNF7G
CPU - AMD Athlon 64 X2 4000+
RAM - 2 x 1gb samsung DDR2-6400
Graphics - ATI Radeon HD2400 Pro
OS - Win XP pro SP2
My system has no problem running all the latest game releases but i find whilst gaming my system will just shutdown. Im not sure how to diagnose why tho.
I think it may be due to overheating, although i have just reapplied thermal paste and cleaned the heatsink/fan.
Im currently running the pc with no side on the case to let extra air in for cooling. After my last shutdown i felt the heatsink and it was still cold so i dont think its a CPU temperature issue, but the chip for the onboard graphics was red hot.
How can i diagnose this problem?
I was also considering the problem may be that the PSU is not sending correct voltages?
