Default Problem with Ati Sapphire x1950pro

Hello there.
As a foolish act I've overclocked my ati x1950pro video card in the recent times. I used a software called Ati Aray Tools to detect how much boost I can give to it. It worked fine for a while, (about a week or so,) but yesterday, while I was playing Warcraft3, the screen suddenly went black, and although I've been able to hear the music that winamp played, my pc didn't respond to any key-combinations, so I restarted it. Some time later the same thing occured, about 10-15 minutes after I started S.T.A.L.K.E.R. Clear Sky, this time without any overclocking.
Since then I can't even start Stalker, as at the moment the main menu appears, the screen goes black again. Warcraft3 howerver did let me play for about 10 minutes before doing so. Now it stops at the main menu as well.
I've tried to reinstall the drivers using Driver Cleaner Pro, but it didn't do any good. In fact these blackouts have become much more recent, and sometimes I can't even start windows because of them.
Everytime it happens, the fan of the video card stars to whirl madly at about 100% speed, but I've checked it, and the card doesn't appear have any burnt smell even after letting it whirl for a prolonged time, and it's just lukewarm when I touch it.
For some time I thought that it might be a hardware issue, but after checking with RivaTuner, it became clear, that the video card doesn't gets hot at all. It has an idle temperature of 47-50 Celsius (my CPU has around 47 as well), and at worst it goes around 60-65. I think that's pretty normal for a video card considering the warm temperature in my room. I've even tried underclocking my Ati, and I've set the fan speed to 80% manually, and also removed one side of the PC's case, but the problem occured just as it did before.
Also, any 3D test or benchmark (or any program at all that uses 3D graphics) does the same thing to it.

Could anyone help me please? Do you think it might be a hardware issue after all? Might the problem be with that little chip at the corner of the card? (I've read in other forums about that little bugger.)
Or might there be a way to fix it without messing around with the card itself?

Thanks a lot for the answers in advance!

it is possible that you have physically damaged the card, it's a risk we take when overclocking. as for what in particular may have been damaged i can't say. i would keep troubleshooting in case it is a coincidental issue, as i have done quite a lot of overclocking of various things in the last 4 years and can't recall any hardware that i've overclocked that i've actually damaged permanently. my first check would be on the power supply as the additional current drawn by the overclocked card may have damaged it.

This might sound noobish but how can I check if anything's wrong with my power supply?

see if you can get a hold of another known good power supply (meeting your requirements of course) and try it with your system, if it works then you've got a bad PSU.
