My sister brought me her laptop to take a look at. It was having trouble staying on. I believe it to be a overheating issue as I hoy hw monitor on it and it was 50-60c. Pretty hot for a laptop.

So I took off the covers, removed battery and hard drive and blew out the dust with a can of compressed air.

I put it all back together and now I get no screen. The computer turns on but I have no picture now.

Whats going on here?
