  1. I recently upgraded the CPU and Power Supply in my desktop computer.
    But ever since the upgrade, whenever I turn it on, it runs for about 1 or 2 seconds, then reboots, and repeats the process until I turn it off.

    Specs before the upgrade:

    Acer E661GXM Motherboard
    Phoenix - AwardBIOS v6.00PG (Oct 15 2005)
    Intel Celeron CPU Family 15 Model 4 Stepping 1 2.80 GHZ
    NVIDIA GeForce 6200AX
    2 GB DDR 400 MHZ RAM
    300W PSU 20 pin (very old)

    Upgraded hardware:

    Intel Pentium E5800 3.20 GHZ
    420W PSU 20/24 pin

    Try clearing the CMOS then check that the time and date are correct. There should be a jumper near the round silver battery on the motherboard. If you can't find it, you can pull the battery out for a few minutes with the computer unplugged. Put the battery back in and the jumper back to it's original position. See if this reset fixes the reboots. The bios CPU settings and timings could be incorrect

    I left the battery out for 3 hours, but it still didn't work. Again, it won't even POST, I have no way of checking the system time.
