If PC restarts always after you playing then this must be one of the problems:
1. Check adaptor
2. Check memory (with some memory test program)
3. Try install XP (or you have 64-bit) and DONT update it(i have about 5 years that conf PC and no format for now:D)
4.Check if there isnt some bad sectors in hard drives.
5. Try oldest drives for Nvidia (one of the best is 44.03)
6. The rest you now (install q3+E+ and this must fucking work :roll: )

oky, thf for help, i test it soon, but i need notice this :

i already formated my PC, tried install widnows 64 bit but same problem then i got my windows xp back and i updated newest drivers of Nvidia, added active coller on passive graphics card (all fans working good and nothin overheat in) and updated windows updates. I already tried turn off all programis on backround by msconfig. Also i tried changed ratio of graphics card to lower (more stability) - didnt help. I already tried search if i have some ROOTKIT in PC, but i didnt....Really i tried all i know but it diditnt help

Spontanious restarting of computer while under load (q3 or similar) mostly indicates on bad,2 weak or *getting ready to die* power supply...so can u tell us what power supply do u have? It can also be RAM,which u can easily check with Memtest...since u said u allready replaced the cooler on the graphic card,I guess its not overheating (I hope).I'm really curious what PSU u have...

300W (unknown manufacture)

his PC crash during prime95 large FTT

So,what do u think doctor?
Imo he should borrow a PSU from a friend and try with that (preferably a brand name 400W or more) because I had problems with my ENERMAX 300W (which is a very good psu) on a much weaker configuration then his (XP2100+,512 DDR,GF4 Ti4200) and had to buy a new 400W.Now it works perfectly.

My Q3 crashes when Snapshots are loading before a game ... it freezes and i have to turn off PC by Power button and then turn it ON again =\ any suggestions ?
