I've got an issue with this machine.
I'll turn it on and it'll power up. The harddrive will begin to spin up, and then cut out, then spin up again, then cut out, with about two seconds between each 'cut out'. It doesn't make it to POST (no bios beeps, no video output from onboard vga).
When I take the RAM out it does the usual "beep beep beep I have no RAM) routine.
Any ideas? I'm currently resetting the CMOS to see if it helps.
If resetting the CMOS doesn't work then try booting with just one stick of RAM.
It's only got one stick in anyways.
When I take the stick out it stops the continuous-restart behaviour. The PC speaker emits a very quiet constant beep (I think I've damaged the speaker itself when I unplugged it), and the hard-drive spins up fully. When I put one or two sticks back in the restarts occur again.
A couple of times when there was RAM in the machine it would actually get into bios, but it soon restarted again. I then switched it off to plug in the keyboard (I was getting the usual post-CMOS-reset 'Press F1 to continue' prompt), and it went back to constant restarts.
I've tried removing the mobo from the case entirely, putting it on a sheet of cardboard and booting from there. I've also tried a seperate PSU out of the computer case in case the PSU was shorting on something.
I'm well stumped on this one.
I'm using a screw-driver to turn it on and off by jumping the pins. I'll often hit a few other pins before I get the power couple, but I don't imagine the low amounts of power associated with the PC speaker, reset switch, power switch and HDD LED are going to fry anything if they're shorted in the wrong way.
The RAM slots also crackle (like dry leaves, not electricity) when I insert the sticks.
I'm well stumped on this one.
