Either you gpu is failing or your memory is failing.. run mentest/86 to see if it is memory

Thanks David, I'm running mdsched.exe memory test now, will try the memtest afterwards if needed.
please see new img attached; sometimes when i restart, the screen splits into 4.

btw, under device manager i can't see the model of graphic card anymore. it should say nvidia gtx 580 . now it only shows "vga standard...".
what's the best way to test the graphic card?

The screen goes funny like that when the video card's memory is bad. This usually happens when that memory is overheated for too long. This is not reversible (it won't help if you clean out all the dust now, make sure the fans run properly, thermal transfer pads and paste are OK etc., as the damage has already been done). The only thing you can do is to replace the video card, which on most laptops is a big problem as it usually is integrated in the mainboard. It is also expensive, as replacement mainboards for laptops are expensive, and also if the video card is separate, also that is expensive, and either are usually hard to get.

So basically you will have to look for another laptop.

The last screenshot was caused by a BSOD. Also that could have been caused by overheating, or sometimes it also happens when you power the system off without doing a clean shutdown.

i have had good results when i could renew the heat paste on the video chip - so worth a try
while doing this, renew the cpu heatpaste also, and of course, clean the system from dust, and verify the fans are running ok
