Dell Optiplex GX620 Blinking Green Power light & won't start!
I am new to this excellent forum and wondered if anyone out there could possibly help......
I have a Dell Optiplex GX620 Desktop PC. Several weeks ago I had a slow flashing amber power light, indicating a PSU or switch fault. Firstly I replaced the switch - made no difference. Then I replaced the PSU - The slow flsahing amber light has now changed to a blinking (very fast) GREEN light on the power button.
All of my research so far has suggested that this suggests the PC is in standby mode! But the PC isn't even switched on - no fans running etc. In desperation I have even plugged a USB mouse in to see if I can "wake" it up! I have a amber AUX_PWR light on the Motherboard which is on.
Nothing happens when I press the power button - no matter for how long I press it in!
Has anyone got any ideas?
Many Thanks in advance
