Heh I'm usually the one giving others advice, but this time I'm seriously stumped with my current problem.

Ok well, I'll start off with my original problem I had a week ago which relates to the problem I'm having now. I had to restart my pc for something (can't remember what) and was met with a "No signal" message(before posting and everything). I was using my old FX5200 at the time as my last psu had blown and my spare psu didn't have enough juice to my my 7950GT. Anyways, after eventually figuring out that clearing the cmos might help, I cleared it and I was able to get into windows. After this, whenever I tried to restart I would get the "No signal" message again, and I would have to clear the cmos to be able to get into windows. I flashed my bios to the latest version and everything was fixed and worked perfectly.

Now the real trouble came today when i got my new psu. I installed it and shoved in my 7950GT excitedly, but was met with the same "No signal" sign AGAIN! So I cleared the cmos and I was able to get into windows, but obviously I am not able to install any drivers for my card cos when I restart it just give the no signal error. I tried flashing my bios to previous versions and back to the new version but it doesn't help. Whenever I try and change anything in the bios I get the no signal message again. I've tried loading the fail safe and the optimised defaults, but I would just get the no signal and the setting would revert back to what they were previously.

I've been googling the whole day and cannot find one person that has had the same problem as me. Sigh, all I wanna do is play some real games! Been surviving on diablo 2 and dota for the last month which the FX5200(:sick:) can barely play.

Any help will be greatly appreciated!
 
Ye it does, I've tried that and tried putting my old 5200 back in but it does the exact same thing :(
 
Ye, there are only two options in the bios. One is "Onboard/AGP" and the other is "PCI", the first option is selected by default (can't change it even if I wanted to).
 
Tis weird, though after I clear the cmos it works fine. I don't get it :(

I can't even reinstall windows cos changing the boot priority means changing settings in the bios, which means no signal. SIGH!

I had the exact same problem before Christmas with my 7800GS and BenQ FP91G+ LCD - no matter what I tried, I just got the "no signal" just after the POST screen.

I eventually gave up and uninstalled my graphics drivers, booted into Windows VGA mode, downloaded and installed the latest nVidia drivers - works perfectly again after that.

Otherwise uninstall, boot to VGA and reinstall your current drivers as fresh...

Can't install any drivers cos they require a restart, which just leads me back to the no signal screen :( (which is before the POST)
