My system is a P-4,2.4Gb.,2Gb(333)ram,200Gb H.d,S.B.Audigy,Ati9700Pro,GA-8INXP,400W power supply, Win. XP.Pro(SP1)+DX9+latest drivers(Catalyst 3.2).My 3dmark2001 scores are 13900-14000.That is satisfactory considering the hardware I have.I should be in the 15000+. Ever since I put this system together it has been very unstable! I even did a reformat on the system & still I get crashes. Either it will freeze & I'll have to reset or the resolution will drop down to 640x480,I'll have to reboot & I'll get a error message saying my video device failed pionting to my ATI 9700Pro & or its drivers. So I replaced the card with a new one & re-installed the drivers & still it CRASHES!!! I don't know what to do? This is driving me INSANE! I'm thinking of replacing the no-name 400w power supply with a name brand. If that doesn't cure the problem, I'm going to switch to the GA-SINXP. If that fails I'm going to take up another hobbie!
