I have a Dell desktop with XP and I need help. About a year and a half numerous and numerous error/boxes keep popping up. Every time I click the X box to clear it other continues to pop up. We tried every then just unplugged the power and now only the Dell logo reboot/restart showes then a black/blank page shows. Im able to press and open the F2 & F12 Boot Device Menu. I do not have or can not find the starter disk. Please HELP what can I do. Thanks
