Hi there, now I'm hoping this is just something simple. The computer was working.. it would boot windows xp, but I could not enter into cmos, when I tried it would leave me at a blank screen. That was for 2 days. Now it won't even boot xp at all. I still cant enter cmos, I get the bios screen at the start then thats it. I can boot media programs like mythbuntu and xmbc from a CD. But nothing happens If I put a windows xp cd in. Thanks in advance.
