USB + Network ports not working after PS failure (ASUS P5B)

[OblivionMage]

ASUS P5B
WinXP SP3
E6600
Corsair 550W PS (was an Antec 450W SmartPower that failed)



My power supply failed (computer wouldn't boot), and upon replacing it I found that none of my USB ports, or Network ports (ethernet), or sound ports (all off the motherboard), would work (this includes the USB ports added with a PCI card).

Whenever a device is plugged in, I get a 'not-recognized' error. I was getting CMOS Bad Checksum Overclocking Failed (I don't overclock) with the failing PSU, but not since it's been replaced.

Note that my PS/2 keyboard and mouse, as well as video, are all functioning without error.

I've tried going into the Bios and loading 'setup' defaults - no effect.

I've also tried a reformat to no avail. What's the next step?

Bios update? CMOS Reset?

Thanks ^^

I just has to RMA my ASUS ws P6T6 Revolution mobo. It took 20 days to send out and get back directly to and from ASUS.I hope you purchased an extended warranty. It sounds like your usb ports are done.That was the same problem I had.Some thing simple could have fried mine.Just make sure you are very cautious and I know it was not your fault but it is a pain in the a**. I would suggest contacting New egg.That is where I purchase all my parts from.In 2 years I only had 1 problem=this mobo.Since then I just got a Gigabyte mobo and everything posted first try-no issues,so good luck,I hope u resolve the issue.

Sometimes motherboards operate funny.A last resort would be what the guy did (the link you gave).He took out all his R.A.M..Just start with one stick of ram and your psu ,your processor and your proc fan.Then try your graphics card and so on.....
