Hi guys, two days ago during pratice my PC exploded .
My power suppy died and i bought a new 1
I had to format windows (didn't start) and after it all seemed to turn back to
normality.
This moarning i started quake and after 2 secs i was in my pc restarted... I can use my pc but i can't start a game without havin that restart.
I downloaded every driver and tryed everything but nothing has changed.
I think i have troubles with my video card but quake is a game that can be run on a mobile phone...
Who can help me???

There are 2 possibilities

1. VGA can't handle 3D mode
2. bad blocks on RAM

Try to run some memtest to eliminate possibility no.2 or try to open as many programs as you can in the same time (fill the memory) If windows will stay stable there is smth wrong with your VGA card.

Thx Yellow... i'm on vista now....
After a memtest (i got 2 blocks of ram 1gb per block) one block showed me about 110000 errors and the other 1 was good.
I had this block with errors in the last 3 months and it gave me no problem... i think probably the vga 's gone or maybe need correct drivers... I'll try to restsrt quake without the broken block...let's see!!! Ty for replyin me.
