How long has it been since the chips, heatsinks, vents and such were cleaned? This item is noted as a YEARLY TASK for the vents at the least. I find most laptops never are cleaned.
my dell latitude d610 laptop while on suddenly screen fades with lines of all colors verticle and horizontal appears and screen totally goes blury and computer freezes, then I have to turn it off and re-boot again some time it will do it again and again and eventually it will be ok. laptop remain work fine for few weeks and suddenly it happens again. i re-installed and updated all video card drivers, ran dignoctis, it all came ok, cooling fan is working fine too. Can someone tell what could be the problem? Thanks
