PC freezes, rectangles shown on display

[CrazySaguaro]

Has anyone ever seen an error like this? The PC freezes once or twice a day
with these crazy rectangles on the display. The PC has Windows XP and is a
Lenovo T60. Windows doesn't even have time to respond and no errors are
logged in the System Log that I can see. Upon a hard restart, Windows does
not show the F8 boot message or come up with any errors/popups when I reach
the desktop.

Thanks for any help.

This is a hardware issue, possibly overheating, bad video chip, or other
failing components. Contact Lenovo tech support.

From your 1st photo, I'd say it was failing Graphics/video Card.
Being a laptop, it is normally Onboard Graphics(embedded in the Motherboard).
Is the laptop new?

Thanks Malke - that is what I thought. It's a corporate PC, thankfully, so
I'll bring it in to trade for a different one tomorrow.

There have been some recent articles about Nvidia GPU chips failing.
G84 and G86 and possibly others.

There is a mapping between chip code name (G84 or G86) and their
marketing names, here.
