Oh ! It has 450 watts of power supply (Intex SMPS). Now, I'm guessing biased towards the AGP rate. And my doubt is getting concentrated at AGP rate. If I can change the AGP rate from 8X to 4X, I can check it out. Coz, most of the people with this video card having the similar kind of hardfreeze problem across OSes.
Unfortunately, the person to whom I had taken my PC to solve my problem, has little knowledge in BIOS settings and could not solve the problem. But he tested the PC with another PCI VGA card, in which the PC is working fine, means there some thing wrong with the DRIVER of my AGP the card (FX5200). It boots normally and when I try to launch any application it freezes. So a combination of BIOS settings and driver is causing the problem.
That may mean your AGP graphics card has a problem - maybe a heat issue. Then again, it's just a GeForce FX 5200. What driver are you using now?
Yes, friend it seems that there is some issue with this AGP card and there is nothing in BIOS/driver/OS settings. I'll replace the card. FYI, yes the golden color heat radiator plates of the card will certainly burn my fingers its toooo hot. And none of the driver versions worked for me, I have tried my hand with each driver release from nVidia. Thank you all for your support.
Yeah, if that's the case, you should try replacing the card. Although I cannot figure out why a mere BIOS flash can cause it to behave like that.
Maybe, if that's what he did after the flash. Cause the BIOS flash utility usually resets the CMOS to default settings after a flash.
