If you suspect the BIOS is corrupt, there is something to try. In the BIOS, if you can get to it, is a factory reset, or factory default settings. Another approach if the default fails, is to remove the CMOS battery for two minutes and replace with a new one. That should have forced the firmware chip to unload into the CMOS chip and any virus should be gone, or another source is at fault.

Are you getting screen corruption once Windows boots up?

99% likely to be a hardware fault that one - video card/memory. The fault appears to be address based (position and distribution changes with video mode) so probably going to be bad RAM.
As jonuk76 has mentioned, whether the corruption also appears once Windows has started up to the desktop will be a further indication.
If the system was also crashing, RAM is further up the list for that reason too.
