I'm trying to fix a Dell Dimension 4600C. This PC turns on whenever feels like it.
I unplug the power cord and the light on the mobo stays on for about 10 sec which makes me think the PSU might be bad, but I don't have a another one so I can't test it . I removed the battery and nothing. I removed all the devices (CDROM, HD, etc) leaving just the mobo connected and nothing. Like I said, sometimes works... sometimes it does not.
"I unplug the power cord and the light on the mobo stays on for about 10 sec". I know this is not normal..... :-(
Thank you for your help guys!
