Hi guys, I am encounterin' some problems with my USB of my laptop and hope u guys can help me out with them.
I am currently usin' an IBM X40 laptop. Things have been workin' fine. Since I had too many craps on my comp, I decided to format my C: to reinstall XP (SP2). However, I was playin' games on my comp last week. My comp encountered a power shortage problem or watever problems along those lines, it rebooted itself all of a sudden. Since then, none of my 2 USB ports are workin'. To further clarify myself, I can tell that the computer detects the devices, includin' mouse, flash key and CD-Rom, however, I can access none of these USB devices successfully. I tried to delete all the USB deivers from the device manager and let XP reload them, nothing seems to have changed. And I also checked my BIOS, USB ports are all enabled.
I am wondering what is wrong with my computer. Do u guys have any clues what's goin' on or wat I should try to do to fix my computer.
Thx.
