XP cannot find the right drivers for existing devices

[Calvin Hui]

My PC is HP a6128hk which has been downgraded to Windows XP Pro since it was bought 2 years ago and has been working fine.

- two weeks ago an iphone 3GS and a Sony DSC-TX1 DC were bought
- cannot get them connected to my PC
- meanwhile I may have done something wrong and eventually resulted in

1) memory cards reader icons disappeared, and no longer working;
2) two usb at the back (from mother board) does not response to any devices (but the LED light is working when the view cam plug in); just discovered that there are two more usb at the front which are not working as well (I have never used them in the past)
3) five unknow devices appears in the device manager

I have tried many methods but cannot fix it, i.e.

a) followed HP website guidelines

b) contacted HP engineers 3 times and followed their instructions, i.e.
- update chipset
- reset cord for the memory cards reader at the front

c) followed some advises by Shenan Stanley and Paul (Thank both)
Ref : I experienced the same situtation

Calvin, can you do a System Restore prior to trying to get the iphone and
Sony device connected?

tried to restore but failed

The problem was fixed by installing another Windows XP on another drive. Now I have two Windows XP in my PC. The new one works fine, while the old one is still having the same problem.
