USB devices freeeze my computer

  Raiden 21:54 10 Mar 10

Every time I connect most devices to the USB port, the computer freezes and I have to restart it by holding the power button on my desktop computer and turning it on again.

This always happens when I plug in most things like memory sticks or printers. The oddest (and most annoying) thing is when I start my computer with the keyboard and optical mouse plugged in, they work fine, but if I unplug one of them and try to reinsert it, (even into the same port) it freezes the computer like any other device.

Also, my portable hard drive works perfectly when plugged into any of the ports. I've tried the memory sticks and printers on other computers (and a PS3) so, I know it's not them.

I am running XP SP3. I've tried a few things to rectify this problem: Reinstalled the drivers, enabled USB related services, entered Safe Mode, checked the ports for physical damage and disabled some ports to check for power supply problems. Any more suggestions would be greatly appreciated! :)

Better put a Green tick as Resolved, on one of the threads, saves confusion.

Possibly a glitch in the Registry, try running Ccleaner, might help.

I tried CClearner on the registry (several times!) and even did a checkdisk during the boot up, but the problem remains. Any more ideas? I really hope it's not a hardware fault.

Are there any Yellow exclamation marks along-side anything in Devices?

Everything is working perfectly according to Device Manager.

So is there any thing else I could try? This is a wild shot, but could it have something to do with any malfunctioning electrolytic capacitors?

but if I unplug one of them and try to reinsert it ...

If you did this without closing down/switching off first, then yes the PC would freeze - those items are not normally 'hot-swappable'. So this could be the root of your problem.

But plug and play is an active service on the computer.

As it is, on just about all computers - but not all peripherals are plug & play! Serious damage can be done if used incorrectly!
