Overheating CPU / GPU in Toshiba SP6100

Touriqunet · 10-24-2009, 07:45 AM

A friend of mine has a toshiba SP6100 laptop, recently it started to get artifacts on the screen and also gets pretty hot in the cpu fan.
He has Win XP with latest drivers for his card (420 Go).
I opened the laptop, cleaned the CPU fan, checked if the video card is not loose, even took the cpu out and spread the thermal paste so that the heatsink touches all of the cpu and theres no air bubbles. I also noticed the CPU fan doesnt start when the laptop powers up, it moves for a few seconds, then stops, then moves again, stops until the artifacts appear on the screen and the laptop shuts down with a blue screen of death.
I will try to install a temp monitor to tell u guys the temperature the cpu and GPU run at.
Thanks in advance.
I also tried removing the CMOS battery for a few mins, and starting it up again, it worked for 1 or 2 days then the artifacts and BSOD appeared again.

The paste looks to be applied properly.
This laptop is pretty old and beat up, so if trying to clean it again wont work ill just tell him to get a new one or a used one from adverts somewhere.

Sorry for the bump, but i just found out that the CPU fan seems to work only when the graphics card overheats. Basically looks like they are switching, CPU overheats = graphics are okay and GPU overheats = CPU overheats (and fan doesnt start) or just both of them overheating at once
Please, any further tips on how to fix this?
I'd appreciate it, Thanks
Before this comes up, yes i have checked if the graphics card is inserted properly. It is. same goes with the processor
