When I turn my pc on it will work like 5 minutes and then my monitor shuts down ( with a orange light ) like it's off.

Evrything is plugged in right and it's been 3 times to the computer repair guy and that didnt helped ( they putted new video card , main board etcetc. anyone help ? :C

Tried cold booting and/or physically cleaning the pc itself?
Does it work on other monitors? You should try it, maybe that's where the problem is.

- Unplug all the cables and plug them back in
- Try a different monitor

Either that must've been one shitty computer repairer, or a moneyhungry one.

I take it it's not your computer overheating, but just to be 100% sure, download this and check your temperature http://www.almico.com/sfdownload.php
Got any additional info? The first post was slightly limited
