Nvidia Geforce 9500 GT Black Screen

Hello,

I have read about similar video card problems on this site but I think mine is a slightly different issue since I have already tried most of the suggestions posted here. I have an nvidia geforce 9500 GT which I have been using for a while then just one day when I started my pc, I got a black screen right after the windows splash screen. I can hear the windows start-up sound in the background but I couldn't see anything on screen. I restarted and went to safe mode and I can see my screen again. I uninstalled all video drivers, restarted, installed video drivers again, restarted and I'm back to the same problem, black screen. I decided to reformat my hard drive and re-installed windows xp (SP2). Everything seems to be working just fine until I install my nvidia video drivers. Restarted my pc, and it's the black screen again. If I wait a bit, my monitor will say "No Signal". Then my pc restarts. I did the whole process again, this time I tried to install the updated drivers from the nvidia website but I still get the same problem. Your suggestions here is very much appreciated. Thanks!
