Try a deep cleaning (you as a PC tech would know this, or stay inside your comfort zone) as well as new heat sink compound. Then try again. If that fails it's likely time for a new motherboard.

Hi ,
I have a dell inspiron 1564 laptop with windows 8 x64. few days ago I tried to turn it on, once the windows came up ( after the windows logo shows ) I got grey/black screen. here :

I tried to boot ubuntu using live usb, It boots and I can see the HD content but after 1-2 minutes I get the same grey screen.
I think it is hardware issue, tried to vent the RAM + FAN but still the same ..
