Last night, I shut down my computer and in the dark, I must have hit a sleep button instead of the power down button. This isn't normally a problem as I can just press a key on the keyboard and it wakes up. This time however, it didn't do this. I'm using a wireless keyboard and figured that it wasn't working for some reason. I tried plugging in a wired keyboard to the same effect. I tried doing a cold shutdown, still nothing. Whenever it boots up, it just returns to sleep mode.
After an hour of trawling various internet forums for answers, I found out that my BIOS might be corrupted. I really don't want to have to go inside my computer and do various tests on it, so if anyone can help me here, that would be great.
I'm running Windows 7 Home premium 64 bit, and I don't have a recovery disk.
