350W psu could be your problem with that oc running, also as I asked before ...... what games are ctd?

You have the latest WHQL video driver so that is OK

PM800?? Is this a brand name computer? Acer, Dell etc?

[ligitly]

pm800 is the the motherboard and the games are age of empires 3 battlefield 2 black and white 2 command and conquer generals
its a custom computer
what power source would u recommend a 450w

[ANZAC_ELITE]

I have the same problem but it only occurs when I serve on Battlefront II.

I only have 512 mb ram (yah, I know I need more but I'm saving to upgrade to AMD64 sys) but I can serve on Counterstrike Source with up to 12 bots/players at modest settings. I have a few current games (Rome Barbarian Invasion expansion, Heroes of the Pacific, Quake 4, Fable) but the worst that happens is lag and slow load times.

I thought BFII was more demanding and assumed it was ram. lightly has ample ram but crashes alot with different games...hmmm and I have a 450w psu and don't OC. What gives? Same problem as lightly or something else? What do you think, let me know....Thanks!
