Weird Visual Glitch When Scrolling

[koberulz]

Went to use my computer today - turned the monitor on and got a "no signal" message. Turned it off. Turned it back on. Still "no signal" briefly, followed by the BIOS splash screen. So somehow sitting at my computer rebooted it or something? No idea.

BIOS said it'd shut down unexpectedly, how did I want to restart. Normal restart selected.

Windows gave me a message about an unexpected shutdown.

All seems fine, except...there's a weird glitch when I scroll in Waterfox as shown in the video attached, where small portions of the screen seem to take a split-second longer to refresh than the rest of the screen does. Not sure if similar issues occur in other circumstances or not.

It's always in exactly the same place.

Hi is this a laptop or desktop computer. you should update your system specs. blow out all the dust from computer it could of shut down do to over heating.

Desktop. It's been absolutely freezing here the last couple of days, and I overhauled the bejeesus out of the cooling system not all that long ago, so I doubt it overheated.

In any event, doesn't explain the visual glitch. NVIDIA did have a graphics update pending, but installing that didn't resolve it.

do you have a graphics card or is it built into motherboard. if graphic card remove it and use onboard graphic if motherboard has it. this will tell if it is a card issue.
