The baby pulled out the power plug when I was working on the internet (Chrome) and when I turned the computer back on again several hours later the screen resolution was massive (but I've changed the screen resolution so that's fine) and when I scroll down it does this: a line goes down the screen sort of updating it to what was lower and if I use the scroll bar on the side it is literally stuck until the whole screen is updated. The lagging and updating thingy also happens when I move a small box, ex. a word document that is restored down. A line bringing up the update must finish before the box moves. It really is annoying, and please help someone!

Quick summary and what to check first: the vertical “repaint” line and the desktop freezing until a full redraw finishes can be caused by one of three things — display-driver or OS corruption from the abrupt power loss, a failing GPU/VRAM or cable/monitor problem, or a system resource/acceleration issue. and are on the right track with software/driver checks, but it’s worth a short hardware/boot test first to narrow the cause.

First diagnostics (fast, no changes): reboot and watch the BIOS/UEFI or vendor splash screen. If the vertical redraw appears before Windows starts, it’s almost certainly hardware (video card, cable, monitor, or PSU). If the display is fine until Windows loads, the problem is likely software/driver-related. Also try a different video cable and/or a second monitor, or boot a Linux live-USB — if the problem disappears there, Windows is the culprit.

If Windows looks responsible, run safe-mode or a low-driver boot (as suggested) to confirm. Then check and repair system files and the filesystem; do these from an elevated Command Prompt and back up important data before running disk fixes:

sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
chkdsk C: /f /r

After those, check Event Viewer for disk/driver errors and update the display driver from the GPU/vendor download page (this follows ’s advice but do it after you’ve ruled out hardware).

Hardware checks if software fixes don’t help: reseat the video card and RAM, verify the GPU power connectors, try the motherboard’s integrated video (or swap the card into another PC), and monitor GPU temperatures/fan behavior. If artifacts persist in BIOS or on multiple monitors, consider RMA/repair for the GPU or PSU. Finally, if nothing else resolves it, back up data and consider a System Restore or clean OS reinstall.

Assuming you are running Windows, then boot into safe mode, login, reset the resolution if necessary, and then reboot. This usually works for me, though your mileage may vary... :-)

Thank you so much! I'll do it right away :)

Any luck with that? If not, then you may need to boot from the recovery partition and tell it to restore broken windows components.

Remove and re-install the graphic driver on your PC.
