I have a Compaq Presario 7212 (Or Compaq Presario 7210 ) AT style motherboard with a Pentium I that I was installing a secondary harddrive into.
Everything was working until that point, it passed every Norton Utility and Compaq diagnostic test.
The system was running while I was looking at some connectors, I accidentally kicked the harddrive cradle, moving it along its rail slightly and then everything shut down. The power supply was making a weird high pitched noise, as if water was boiling, for a short moment. I'm not smelling anything burning inside the powersupply or on the motherboard.
Now the board no longer wants to boot. The only things that turn on for a moment are the keyboard lights.
The harddrives still do their thing when I turn on the power, the harddrive light from the motherboard even lights up. But the 'power on' light from the motherboard does NOT. My screen does not get any signal either.
I have re-inserted every powersupply connector. I have put back the original 2 4MB EDO ram simms supplied by compaq. I disconnected the harddrives, floppy drives and tried different configurations. I switched out the Pentium I CPU for an other Pentium I. Tried a PCI video card.
None of that has worked, what should I try next?
Thanks for reading.
