umm could be but I might have to add that it's a laptop... that reduce my choices ,

once I tried to change it but IIRC I had read somewhere that if my graphic card was attatched I was doomed... and that it was going to be impossible to change the graphics card.

I have a Hp Pavilion dv2125 btw

the overheating could also be a possibility , my lap isn't very good handling heat
