Video Card Fried?

[Bamudan]

Hey, I'm new here and i have a uber problem so i'm sorry for being a first-poster asking for help. >.>

My computer has been running uberly hot, running a prescott P4 3.0GHz with HT, so, it gets up there. Today i took the casing off to replace the thermal paste on the heatsink, and when turning the computer back on, it booted normally...

Good news is, it's running about 20C cooler.
Bad news is, when i booted up Speedfan to check the temperature, it shut off..So i turned it back on..Monitor does nothing. So i'm like..oh man..Vidoe card fried..So i changed it, i had a spare laying around. Turn it on, monitor does nothing!

BUT, I plugged my monitor into the onboard slot of my motherboard, and it works.

So i need to know something...

Is it the motherboard thats fried, or the video card? ( I tried 2 )

Any help would be appreciated. ^^

Hmm... what kind of PSU do you have. Seems that your PSU might be dying.

 

[Bamudan]

I don't know. O.o Some generic "EXTREME SWITCHING POWER SUPPLY" that came with my case. 400W.

Hmm, PSU's that come with cases are usually a piece of sh*t. Take a look at the PSU's sticker. Tell us how many amperes (a) it has on the +12V rail. It should have at least 18-20A to run properly.

If not, it might be time for a new PSU.

BTW, can you try your video card on another PC?

It says 25.0A for +12. And i don't have another VGA compatible PC. They're PCI-E. It worked for about 3 minutes then rebooted again.
