Need some educated experience here.
I'm currently working on a customers laptop which is an Alienware m5500i-R3 model. After some research it is actually considered to be an Alienware m5550 series by the manufacturer, don't ask.
As I found through research, there are multiple type overheating issues with this particular brand of laptops through out various models.
This particular laptop is experiencing what I believe is at least a GPU overheating issue. Upon start up the typical Alienware Alien head logo appears with some fragmented colored lines around the outside border.
When going into "safe mode" the screen is fine for what I assume is probably low resolution graphics?
OS is Windows Vista.
I managed to get into the Operating System through a regular start up once so far out of about 3 times (with normal looking graphics).
After reading about the GPU and CPU overheating issues I decided to at least lap the heatsink area and then apply a fresh coat of Artic Silver 5 to the processor surface. What I found when I opened the case is some type of thermal paste (factory) that at least resembled in color, Artic Silver on the processor. The substance was not fluid in anyway shape or form and more resembled a 3/4 baked cookie dough. In other words it either saw a lot of heat over an extended period of time or was a cheap knock off thermal paste that simply didn't hold up.
The video card is an nVidia GO7600. My question is would it be ok to also apply a thin layer of Artic Silver 5 to the top surface of the GPU processor? Currently it had/has nothing on it except a baby blue colored pliable silicone (gooey) sheet covering it.
If I can apply thermal paste, would it be better to leave the baby blue gooey silicone covering or remove it altogether?
There is no heatsink touching the graphics GPU so if I do remove the blue gooey silicone covering, there is a possibility that if the thermal paste heats up too much it could make contact by fluidity (flow) to the surface contacts.
Looking for opinons in general and especially those with laptop experience.
