    hello

    i have a intel desktop d915pbl board and intel petium 4 processor. this morning it booted up but now. i am not sure if it is the memory the cpu or the mainboard itself. i know for a fact that the power supply is ok because i can see a greenlight on when the power supply is hooked up. the fan on the processor also wont work or run. i am wondering what can i do to fix this?

    or if it is needs a new mainboard.

    please help

    Sounds like your psu went bad, or the mobo. PSU first.

    Fans runnig and green lights do not mean it is not a power supply problem. Often only one of the voltage rails on a power supply may be wrong or bad. A power supply is also a less expensive trouble shooting step than pulling CPU's and possibly ruining one.

    As a suggestion, Disconnect everything from the power supply and motherboard such as optical drives and hard drives, sound cards, add in PCI cards and try to boot the computer with just the CPU/Video/Memory installed. If these are all good and the power supply is good you should at least be able to boot to the bios screen. If you can then add back components one at a time until you install the one that causes your system to not boot. If it is the power supply, many mom and pop shops have testers that will tell you your power supply is bad.

    BTW make sure that the 4 pin P4 connector is attached properly to the motherboard as this will also cause your system to not boot.

    Or take a power supply from another working computer and try it in the one that doesn't work.

    Because fans and lights come on means jack all, it can still be the PSU. And actually you want it to be the PSU beacuse its much cheaper and easier to fix then if its the motherboard thats shot.
