I've been away from the forums for about a week because my trusty gaming laptop decided to die on me. I had left my laptop on all night downloading XCOM: Enemy Unknown from Steam. In the morning I decided to have a quick play and when I started the game all I got was a screen of coloured squares.
A quick reboot and I tried Saints Row IV. This time the screen went blank and the laptop switched off. So I left my laptop to cool down, it had been on all night.
After about an hour I tried to switch my laptop on. Everything lit up and the hard drive whirred but no screen display. I connected my laptop up to my TV via HDMI and again no display. As a final act of desperation I connected my laptop to my TV using a VGA cable. Success, sort of. I got a display but it was corrupted.
Messing about with the laptop I found that if I applied pressure to the keyboard, using a screwdriver, around where the heat sinks were I could get it to work long enough to boot into safe mode. However after a minute or two the screen corruption would come back and the system would crash.
I decide that the problem could be one of four things:
The GPU was fried.
The GPU had become unseated from the motherboard.
The solder on the GPU had fatigued. (Solder can crystallize over time reducing it's conductive properties).
The thermal compound on the heat sink needed replacing.
I was hoping it was the last one as I would be able to fix it. So working on that assumption I decided to perform some laptop surgery.
First I took it apart. Removed the gunk from the heat sink, reapplied the thermal paste and finally reseated the heat sink. I tried out my repaired laptop and, success, it worked!
Now all I had to do was re-assemble it and hope everything still worked.
So for about £10 I repaired my dead laptop and saved myself buying a new one for about £600. Yay!
