I'm not sure what's going on, but, I bought the Everex GreenPC awhile ago, put Ubuntu on it, and all was working fine. Now, I mainly use my laptop so, I haven't used the PC in awhile and when I got on it, any time I pressed the "Shift" button on the keyboard it types a "4" and any time I press the space bar it turns down the volume...

It's just a generic PS/2 US keyboard... It worked before, I don't really understand why it's not working now. All except those 2 keys work fine.

I tried reinstalling ubuntu and it still does it.. so it's a fresh install... But I'm lost. Any help?

Thanks in advanced.
