gateway 600gyr laptop problem

After a few minutes the scrren fills up with many pixels and can't see what is on the screen.. I pulled the keyboard and it looks like the fan was not running.. I order and installed a new fan/heatsink. now the fan runs until it boots up and then stops, not to start again..then the screen gets full of pixels (?) again.. I thought the fan was the problem so I hooked it to a power supply to make it run all the time.. but the screen still gets unreadable..
any help anyone??

thanks for a reply

don't know about you pixels but the fan action is normal,only comes back on when it gets hot .
i would guess the pixels problem is either lcd or video driver related
