Default Laptop white screening some of the time

Following an investigation into why my laptop wouldnt power up i took it to pieces. I fixed the problem of the power up found out it was the power supply DUH,

well when i put it all to gether it booted but then went white screen on me.

Ok below 3 pics for your info

Advent 8115
P4 dual core 1.73, 2gb 533 hz, 100gb hdd, shared gfx

pic 1 - laptop when i leave it couple hours maybe to coold down?

pic 2 - laptop when it has been reset or turned on and left to boot into vista

the underside - mobo and brass heat pipe sinks - dual core cpu and gfx chips

** possible cause for my troubles - i did take heatsink off and not replace the compound
i do also have now put some on but ran out so dunt think it is enough

- i can when it boots with a pic boot up safe mode and even run warblade (games)
- i can hear vista boot up even if the picture is white / garbled white lines

can anyone confirm what this problem may be? i think overheat gfx or cpu
or a solution (i will pop out and get compound tmoz and try that first)

thanks for any ideas

known not to be a problem

- all cables / ribbons / connecters / hinges / bolts secure and working
- hdd - have two same laptops only does it on mine tried my hdd in other and works fine

I would say it is a double whammy. First you should apply some thermal paste to the CPU. It is more than likely heating up way to fast and causing you some ill effects.

The 2nd image is a GPU issue. It could be related to the CPU as well. But first things first, apply thermal paste.

okies righty am now waiting for some thermal pads and grease to come off fleabay,

after a lil research if found that these pads are once only use.

My suspicion is this could be the cause as my gpu and 2nd core cpu having issues with heat

both have one of these pads on as my main cpu is raised leaving a gap between the cooler system and the gpu / 2nd core

thanks for the feedback was a good clue to the problem
