Hi Shane,

Welcome to PC Help Forum!! We have a great team here, who will no doubt be able to assist you.

The next time you boot up, can you enter the BIOS (Tap DEL on boot). This is assuming your keyboard works during startup, if not you may have to plug your PS2 back in for this. When in the BIOS, look for something relating to USB devices on boot, or PnP on boot. If these aren't selected, then your Pnp devices won't respond until they are plugged in again (as you have had to do).

Select those mate, and let us know if it helps.

hi scouse
thanks for that info.. i went and looked in bios..nothing...looked in chip set config.. usb controller is enabled and usb device legacy support is disabled.. enabled it and tryed boot up with usbs plugged in..same thing happend again
black screen slow boot up and no usb controllers..tryed all devices on another
pc they all work fine.. its getting closer to those flying lessons..
thanks ..shane

back again..forgot to say i tryed a pci usb card to see if it would work any better.. but the same thing happens with that too...

Hi Shane,

Do you have any other USB devices plugges in at startup? ie Hard Drive, modem etc? If you do, are these devices working ok?

hi scouse
no i have no other usb device plugged in.... like i said if i uninstall windows xp
sp 2.. and go back to basics..all usb's are fine no problems what so ever..its only when i put sp2 back on that it all goes out window..
i know its not a new m/board asrock k7vt4a pro. with a amd sempron 2800+ with 1 gig of memory... but i checked hand book and it says all 6 usb's are 2.0.. ports..

Hi Shane,

I know you said you'd updated the drivers, but it all points to driver incompatibility with SP2. Do you have any other USB devices you can plug in for next boot up? Just to see if it's a complete disaster or not! Also, can you list the devices you are using, and i'll try find alternative drivers for you, to see if it makes a difference.

This is the main troubleshooting tip i've found so far

Incompatibility of drivers
You might encounter problems with old drivers of devices (especially USB devices). Symptoms: Windows freeze, or devices (for example scanners) don't function properly. In such cases, disconnect the device and search for an updated driver.
