System Lockup when gaming

[Hakon]

I have recently built a new custom system and everything is in working order until i run a program with high demands. The system will lock up and the only way to get out appears to be a hard reset (button on the comp).whenever loading up either Dead Space or FFXI after about 20 minutes of gameplay the entire system locks up or bluescreens.


System Spec

Asus A8N-SLI SE
AMD Athlon 64 X2 3800+
2 gig RAM
ASUS ATi HD 4850.

thank you

is the game compatible with XP? or can due to temperature

if not, try uninstalling the game.. completely (delete folder and saved games ect.) run complete scandisk... defrag... reinstall
happened to me once on a game.. seems game installed on a bad sector...

Temperatures are running at normal levels which leaves me to suspect two things. Either the PSU or the mobo.. has anyone got any light to shed on this one or know any good diagnostic software that you can recommend.

Try different display drivers... also change the registry settings to stop it auto-rebooting on BSOD. bluescreens. is due to hardware failing so try to check Hdd for bad sector ,also check for motherboard and graphics card with cpuz

Have you overclocked your CPU? Perhaps instability there. Or otherwise, it's a driver error somewhere. I've had freezing from 3Dmark05 and bf2142 before. I fixed the 3dmark05 freezing by lowering my overclocked gfx and cpu. The bf2142 problem was because of sound card issues, Audigy 2 & its EAX software.

Well if your graphics came overclocked, it 'shouldnt' be a problem, as they are stress tested. However you can try to underclock it. just remember your original settings before you change it.

this is similar problem to my resolution problem... i previously tried my 2nd PCI -E port and there was no difference... however... i swapped to the 2nd port again and the problem has stopped... it was a faulty PCI-E port....
