On wake, slow and white bars, fixed on restart?

Hello, recently (Ive had my build for 2-3 years atp, swapped gpus a few times) sometimes when I wake/turn on my computer, itll be insanely slow/laggy, and have some random (often horizontal, sometimes vertical) white rectangles, which sounds like the beginning of a gpu failure, but if I restart my computer, its perfectly fine, and will have no issues for a week+, which kinda just baffles me, since if it were a hardware issue it shouldnt get fixed by that. Ive tried updating drivers for gpu, is it possible it could be a bios issue? Idrk atp, thanks for the help
