this has happened to me 4 times today. it happened before but that was after a month of uptime. i don't think the laptop has long for the world but i can't afford a new machine right now. anyone have an idea on how to fix this situation?

Do you know whether it is a hardware problem or a software problem?

has to be hardware. happened on ubuntu this morning and when i got home. booted windows 7 and it happened on their as well. pretty sure it has to be the gpu. thought i had it under control because i went over a month without it happening once even when leaving it running all day. until the last 2 days its happening alot.

Do you know what GPU you have?

As in, manufacturer and model?

You could hope that it is getting hot.

I'd remove the keyboard & have a look inside, it should be somewhat dusty, remove the dust.

I like to use compressed air, if you do the same be careful not to let the compressed air spin any fans as it can over rev' them causing damage to the fan(s).

Some people even think that the over revving fan can generate electricity & cause damage. Though I think that it is highly unlikely.

Beyond the dust you could just gently check any connections though it is unlikely that connections are your problem here.

It is a major problem with Notebooks & the like; few people have access to the components required to fix them, beyond RAM & drives.

Good luck.

If I had to put money on it, I'd say that either your video card is going bad or the connection between the screen and the mobo is loose, pinched, or damaged. Just a guess though.

Actually it can, but most cooling fans have a diode that shorts out the reverse current generated by the fan. As long as the diode is intact, you're good.

I agree with cleaning the dust out and, if you feel comfortable taking it apart, checking the cable to make sure it hasn't gotten pinched and isn't breaking down from movement.

I'd also reseat everything while you're in there.

Do be careful and guard against static.

Try the suggestions offered here but also replace the thermal paste while you have it open. Artic Silver 5 is a good type.

If that still fails and it's out of warranty & you have no other recourse you could try reflowing the motherboard in you kitchen oven. Many people have achieved success with this. Newer lead free solder seems to cause some problems at times which could be corrected with a reflow. Issue seems more prevalent with products using nVidia GPUs though.

Searching google will provide you with some good examples.

Examples:

There's also a class action lawsuite related video issues on some HP/Compaq laptops so maybe you can get some money or get it fixed/replaced even though outside of warranty.

Looks like the video card is artifacting. Make sure you DO check your connections. The one time this happened to me, it was the PSU connection to the motherboard, though not on a laptop.
