Hello there, I am having some problems with my comp and was wondering if anyone here could give ms some direction. First off i have a home built comp. Im running windows xp pro, 500w power supply, 1 gig of ram, 80 gig hd, an amd 64 3500+ processor, mother board is a GA-K8NSC-939 with the nForce3 250Gb chipset. Video card is a nvidia Geforce 6800 GT. The problem is that when i am playing some games like (Hitman-Bloodmoney, or TombRaider) my computer will after a few minutes shut down all video and freeze. my computer will still be running but i have to manually shut it down and restart it because my screen is blank. It also happened the other day playing medal of honor Allied assult (but i have been playing that game for years and that is the first time it has happend and it hasent happened since). I was able to play Tomb raider but had to put all of the settings on low. With Hitman i put everything on low and it happened about 5 or so minutes in....Can anyone help me please????
PS. I also have downloaded all the new video drivers and that did not help either.
Thanks,

Tell us about your 500W PSU. What brand is it, how many amps are on the +12v rails, & how much did you pay for it?

Psu is a DYNEX model # dx-ps500w, I got it at best buy and paid about 70 or 80 for it. I also use to run a antec psu but it went bad. the prob. was happening before i put this one in though. dont know what you mean by +12v rails.

Dynex? did you get it at BestBuy?

It seems suspicious when a site doesn't post specs for it's own product.

yes...i got it at best buy

Remove the side cover from the case & look at the label on the side of the PSU. Post back with the amperages for the +3.3v, +5v, +12v1, +12v2. And see if there's a UL Certification number somewhere on the label...it will start with the letter E & have 6 numbers (ex., E123456)

Try turning down your (ingame) graphics and then see if it happens again

I will do what you state in the above post, although it will take me a few days as i am in transit moving to Atlanta and my comp is packed. Again, this is not the first time that this has happened. I had one other psu that it happened with and it was an antec 500w as well, I just sent that one back because it quit working and they sent me a new one. Dont know the specs on that one because it is still in the box and packed.
