I've got a compaq SFF which wont boot when the power cable is connected to the hard disk drive. It basically flashes on then off. If I disconnected the hard disk power cable I can get it to boot and go into the BIOS. I can even get a floppy to boot. On its own it just doesn't happen. Anyone got any idea what is happening. I've never seen anything like this???????
I'm figuring the power supply is potentially broke but there may be something specialised that I'm just not seeing. Anyone got any ideas???????????? I think the question is probably quite hard.......it's a you know what to look for or you don't.
