Vostro 400 desktop not booting - amber light
I have Dell Vostro 400 pc. Admittedly very old from 2004. I noticed that for a few days I'd put the pc to sleep but it would switch off. However, the other day, when I power the PC up, on the power button there is a faint (and not fully lightened) amber light. I hear a short whir, like you get when a PC powers up, but nothing further. There are no beeps.
Any idea what is wrong and would this would be hard drive related?
