Hay Ghostmaster u done have to redo the OS (Windows) for the printer problem. All u need to do is get into the System Setup Screen and look in for USB Emulation listed in the Integrated Devices and change it to NO BOOT. To get into the System Setup Screen u need to restart ther computer and keep hitting the F2 key on the top row of the Keyboard.
I have been for months now trying to fix my computer.  I am running Windows XP Pro.     I have the following problem   Occasionally at boot-up Explorer does not load.  I have to do the three finger salute in order to get it to run.  Also I noticed after getting a printer that when I boot the computer with the printer hooked up and on.  I get nothing but a black screen with a white cursor in the left right upper corner.  I am not sure if both of these problems are related.  I thought the problem may be due to a bad Microsoft patch that I installed in either June or July of last year.  (yep it's been that long)  I have updated drivers (all of them)  reinstalled drivers.  Nothing is showing as incompatible in the device drivers section.   The only thing I have not tried is reformatting the drive.  I would of done this by now.  But if Dell had of sent me a reinstall disk, then it was either missing, or Dell never sent it in the first place because I don't have it.  I am running a Dell Dimension 4600 (don't laugh)   The new printer I have is a Lexmark All in One X5470 Model.  Yes I have walked through everything with Lexmark.  The last thing they had me try was to turn off the USB Hub Power Management. (It didn't work)  I have yet to use my printer and it is now two months old almost three.   The Lexmark people are lost, and ran out of options/ideas. No I did not hook this printer up until some time after recieving it, because I had a family emergency, and was gone for a while. Unfortunately I found out they go by when you purchased it instead of when you registered it.  Or so that is how I understood them.  If all else fails, I do have a buyer for the Lexmark printer.  (grins)  What now should I try?    
Need to try to reformat drive?
