    The holes aren't placed in a proportionally larger distance from one another just because the PSU itself is bigger. They are all going to be the exact same distance, on the same exact spot on the PSU. At least, they should be for a true ATX unit.

    Good luck and hopefully the PSU is indeed your problem :).

    You are right. I checked out ATX PSU's on several sites, and they are all the same size, 85 or 86 millimeters deep. However, my Compaq unit is about 15 mm larger /deeper than the ATX standard size, about 101 millimeters, and the holes are drilled very near to the edge. The upper an lower holes are dilled further apart ,about 96 millimeters, than the ATX unit is deep. Therefore there is no physical way that all of the holes will fit

    In my brief search of the internet, all of the PSU's in the 200-300 watt range are ATX compatible, and therefore 86 mm deep. I think that I can ascertain whether the PSU is the problem with the unit you suggested, and if it is, I'll worry about the differences in size.

    As long as it powers your system, mounting it by a physical alteration of the chassis shouldn't be a problem at all. Just be sure to run with that initial assumption and concern of the metal filings getting on the other components, that would be bad ;).

    plugged in the new PSU today, and no change.
    Tested the Monitor on my portable and it is OK,
    Removed the 2 RAM boards, and installed them separately, no change

    Any other ideas?

    Strip your system down to just the motherboard, RAM, CPU and PSU. Clear the CMOS and try to boot. If you get nothing and you know the RAM and PSU are both okay, it's either the CPU or motherboard.

    Of the two, I'd go with a motherboard failure if it comes to it.
