Have you tried installing the OS again, or a different one?
Also it would be worth updating the BIOS if you haven't already got the latest.
Also is there an option in the BIOS for a USB mode, as in legacy or native ? try changing that see what happens...
and are we talking about the USBs on the back panel or on the case (front panel)?
Thank you for the reply. All USB ports including the front 2 do the same thing - won't work with flash driives but all work with USB external hard drives without problem. The only bios setting I can see is USB legacy which is <enabled>. Only other option is disable. If I disable, doesn't my usb keyboard and mouse not function? I have not tried reinstalling new OS as I am trying to see if there is a fix first.
it's just a bug of xp i think so.
have you tried to boot from any other os like vista and ubuntu
be dont put any tension
you can still try to boot from any other live cd
does the problem still perstist?
then back up all the data in the flash drive into another computer
then format the flash drive
it also might be a virus issue(malware,worm)
it happened to me on dg41rq so I upgraded. It would tell me svchost.exe error..
