PC shuts down after re-assembling

[jotaj]

Hey guys

So first of all, a couple of days ago I turned it on and no picture would come up on screen, I was using HDMI so I tried switching to VGA, but nothing changed.. so I decided to disassemble it all and also clean all the dust out.

Today I re-assembled it and still no picture but now it's even worse... The machine will shut down a few seconds after turning it on.

Hi,
Try testing the board outside the case (it might be a short).
For the no video issue, try a different graphics card or the onboard, if available.

What did you disassemble the GPU or the whole PC?

Actually no I didn't take any heat sinks or stuff attached to the board off, neither did I open the PS

Okay, so you took the GPU apart. You must have damaged something with the card. If you have another GPU try it, if not you are stuck.

So I tried to turn it on with just the board, and yeah it went perfectly. Got image and doesn't shut down.
Tried again with the gfx card and the problems persist... no image and shuts down shortly after.
It's a Radeon HD 4550 if it helps..

I'd say it's either a graphics card or a power supply issue.
Try borrowing a graphics card and testing or RMA the card.

I guess I'lll have to try with another one then. Thanks for the help. I'll keep you guys updated.

Edit: Ok so before I tested with another card i tried another time with my own and all was ok.. perfect image. So I guess the display issue is solved now, but the shutting down issue persists. A couple of minutes after turning it on it goes off.

Check your fan or heat sinks.. Sounds like overheating issue.
