I have this pc, actually yesterday they became two, that sometimes wouldn't boot:
it would just get to the first balck screen, with the:
press tab to enter post, and propmting me to press delete to enter bios
and then it just hangs there
and of course it wouldn't accept either command
Then I try rebboting, and same as above, then I let it for a couple days, I try to boot, and it actually boots fine!
Any ideas please?
