RE: Boot problem - Optiplex 755 stuck btwn Dell splash & Win XP splash
Sounds like a USB connected external drive is going bad. Disconnect all of them. Reboot.
Reconnect them one at a time between reboots to isonlate which might be having the problem.
Keep in mind that the cause of the failure could be intermittant, so you'll want to only have one at a time
connected for testing purposes, else you might think you've found the problem drive when in fact its
one of the currently connected subset.
