ASUS Motherboard P5e won't POST

[zillah]

Hi
I have got ASUS Motherborad P5e,,,,yesterday it did POST today it did not work.

I can see SB LED lights up in green color

I removed all cards and RAMs and HD,,,,only CPU left, and shorted the pin for POWER SW,,,still noting worked, CPU fan wouldn't spin at all.

Unplugged the power supply cable that is hooked to motherboard and hooked it again

If the motherboard SB LED lights up, the power supply is almost certainly working.

Another test I did try this power supply on my old PCs (i.e another motherboard) and its fan and the CPU fan both of them span.

PSU is BESTA PT-550W

Is there any other troubleshooting should I consider ?

Thanks

you tried all possible i think

check closely the board and look if something is burned ;bios chip is ok?

Consider an RMA for your mobo

Also check if the board is touching the case in any way. A last way would be to disassemble everything and hook it up back together OUTSIDE of the case, that worked for me once.

if the CPU fan doesnt light up, the PSU is likely the cause.

those LED lights run off the 5V rail, while the fans run off the 12V rail - its possible that only one rail (of several) inside that PSU has failed.

This is made more likely by the fact that your PSU is a "besta" - its a no-name, generic brand. If its not well known, its likely to be low quality.


edit: and FYI, the minimum for a PC to boot is motherboard, one stick of ram, video card, CPU, and a working PSU.

Maybe the power supply cant provide enough power for your cpu and motherboard. Change another PSU, see how it goes.
