CPU change causes USB to go Faulty?

[SparkyG]

Not sure if this is posted in right section (maybe it should be in the motherboard section?) but I recently changed my CPU from a single core to a dual core and now the USB ports do not work. I have checked the bios, etc and all is how it should be. I can only presume I shorted something while changing over the CPU and now the motherboard is done for..

Have you ensured your BIOS supports the CPU? Tried flashing to the latest BIOS? Reset CMOS?

I did not check fpr CPU support but everything else works and it shows up in bios, the cpu that is.

I have reset CMOS but have not updated the bios yet

What motherboard and CPU is it?

 

[SparkyG]

It is a packard bell Mobo & the cpu is an AMD X2 4200

Ah, then usually with the case of branded PCs the CPU is generally low I find, and BIOS updates tend to be very slow as they don't expect the user to upgrade the PC. I would try see if the PC does support the new CPU, if not then just refund the new CPU and save up for a new CPU/MB/RAM/OS combo.

Well I swapped back to the original CPU and the USB ports still dont work. I must have touched something and blown the ports???

Check any connectors for the front panel USB ports, these will be at the bottom of the motherboard usually, and look something like the following:

Although occasionally they don't have the surrounding plastic, and consist of just the pins.

The onboard ones (ones at the back) dont work either

Have you tried other USB devices? Checked that USB is enabled in the BIOS if possible?

I would try a CMOS reset as well.

I have tried a keyboard, a mouse, a remote receiver, a USB mem stick and a USB HDD in all of the ports and I get nothing.

I have check bios and USB is enabled

I have also reset the CMOS

I shall just buy a PCI to USB card

Thanks for the help Guys
