hi guys
i have a strange problem with my asus EN8600GT graphic card.
Before the problem occurred my PSU used to be 350W max capacity, but it can't supply the whole components so i unplugged the DVD and floppy drives. since then it still have problems and finally it won't boot. then I bought a 520W PSU and it replaced the old one. before replacing the psu i did some cleaning to the chassis and i did remove the graphic card from its place. after i'm finished i replaced the card to its place, but a drop of sweat (i think this caused the problem, but i'm not sure) dropped to the heatsink and almost to the GPU. i didn't dried it up fully and just placed the card to the PCI-E slot anyway.
i turned the system on, and it booted up just fine, but suddenly, seconds after it logged on, the graphic showed a problem. strange colors were almost everywhere on the screen. restarted the pc and the strange graphic happened also during bootup. i took out the card and blow it right to the point of contact of the heatsink and the GPU. the strange graphic problem is actually getting fewer(i.e, there are lesser strange graphic) and there is not even a strange graphic problem when i run windows in safe mode (but there is still some in the bootup screen). i took the card out and blew it again, but the strange graphic isn't getting away from the bootup screen. since then i can only start windows in safe mode and not the normal way (because it will freeze)
Can anybody help me solve ths problem? Is it really because of the sweat or anything else? Does it have connection with the PSU?
I appreciate anybody who can help me.....
(p.s: i am new here, so i apologize if this thread is very long or if this sort of Qs has actually been asked before. i wrote this thread because there are no answers about this problem that satisfy me)

Next time, don't sweat over computer parts

A drop on the HS (heatsink) isn't going to cause a short. When you powered up your computer, which I assume is a tower - what it standing up with the Heatsink facing down? if so, the worse is that it'll drop to the bottom of the case or evaporate within seconds of being warmed up by the GPU.

PSU issues: 350watt barely covers it... but also its the quality. So what was your previous PSU and your new 520? I'm talking name brand and model number. You can spend $25 on a "600watt" PSU that is WORSE than a $45 350watt PSU.

The DVD and Floppy drives only use 1-2 watts when not in use... so it made no difference. There might have been damage from using an underpowered PSU - this also includes the 520 if its not a quality unit.

Try this:
1 - Remove your 8600GT and revert to your previous graphics. Onboard or other card. See if compter operates properly. Your 8600GT could be faulty...

2 - if it works, exchange the 8600GT for another one.

3 - Provide INFO on the power supplies HERE before you do so. If your 520watt PSU is junk, you need to know now. Theres only a few 520s on the market.
