Scrambled screen on boot

[ajhmartin.903]

I'm not sure what the correct forum to post this in is, as I don't understand what is causing the problem...

When I boot my laptop, or sometimes when I lift the lid and wake it from sleep, I see a strange, scrambled screen.

It looks rather this like this image another person has posted online.

It stays on screen for two or three seconds, then everything changes to the normal Windows 8 splash screen, which I can click on once and then enter in my password to login.

After that, all graphics are perfect. I have no issues, no freezing problems, no trouble running games - nothing. Just this strange, momentary glitch (randomly) when I boot or lift the laptop lid.

I've read in a few places that this can be a sign of GPU fade, which is why I've posted the problem in this forum.

I have a Nvidia GeForce GTX 675M/PCIe/SSE2. I've the Nvidia Control Panel and it's been through several driver updates since this problem first occurred. I've also run the FurMark test, which I've seen suggested elsewhere, and after fifteen minutes stopped it. The GPU at that time was around ~100c.

Any thoughts? Thanks.

Might be worth telling us what laptop you have?

If you have not already, strip the fan housing and remove all the dust/fluff that has accumulated in there, and remove it of the heat sink, might also be worth re-pasting the GPU if you have access.

Here are some pictures of a laptop l cleaned for a workmate recently:

Personally l would not run FurMark on a laptop as you have seen it drives it way to hard and 100'c is not health

The fault might indicate poor cooling on initial switch on, so the fan might be in need of a clean also.

Sounds like the GPU is on the way out - had it happen on one of my older laptops recently - at first it was just scrambled text on boot up until the Windows loading screen then it started having problems with video playback - HD videos would randomly result in half the screen intermittently going black and eventually it wouldn't even load into Windows without video freezing/crashing more often than not.
