Nvdia gt 630 problem

[nickzcool]

Guys two weeks back i purchased new gpu for my rig which is :- nvdia gt630 1gb ddr3 (importer name forsa) it worked like a charm.
my rig specifications:-
Mobo:- intel mercury 945
Cpu :- e4600 2.40
2gb ddr2 ram
Intex 450 watt psu
Now when iwas playing darksiders and crisis 1 on low settings on my pc i got really good fraps60 - 100 on a resolution of 800* 600 and on low settings. Now after ending these games. I upgraded from xpsp3 to windows 7 ultimate. And played nacrovision on it it also ran good and even 50-60 fraps on medium settings. While playing nacrovision my gpu behaved strangely an started giving low gpu usage. I managed it some how but now iam trying to play prototype 2 .which dosent even give more than 15 fps no matyer what the settings are no change in frame rate. I even downgraded to xp again but in vain. I dont know what went wrong or what might be the reason for this. The gpu usage on crysis , prototype 2 does not go above 50%
Where as if i run a rendering test it jumps off to 98-99% plese suggest a solution . Iam really dis appointed with performance. Especially after ExPeRiEnCe of what this card can perform.

O RLY? Tell us more.

i know modern game will struggle.but for crysis 1 he should easily run at high.

Crysis 1 is heavily GPU dependent but not prototype ! - you will have low FPS with that processor

guys all i want to ask is that when i installed this gpu crysis and darksiders was working fine but now the gpu usage is not passing above 60% but before it used to go to 99%(both times on xp ... i have installed xp now no same results ) what might be the the reason for such sudden fall .
and why was it working fine before . i cant upgrade my mobo and cpu all ican upgrade is my ram and psu . tell me if that can make a difference . guys iam not a heavy gamer i only play games to kill my time and i dont games on high resolution or heavy settings . so gt 630 is enough for me . what i cant understand is that if my cpu is bottelnecking my gpu why was it working before .

Maybe you have a virus, or, most likely, your HDD starts failing. Usually old HDDs that are at the end of their life cicle can cause quite major lags in games and other applications, even if other hardware's in a good state. Check your HDD's state with "Crystal Disk Info" or other similar software.
