I have a Dell Inspiron 9300 laptop. I have McAfee antivirus software and it is updated regularly and I use Windows XP as my OS. I had recently dl'ed the Service Pack 3 and needed to reboot my system for the update to take effect. When I restarted my computer I lost power. After recharging my battery, I tried to boot my computer and it fired up like normal. Boot screen, windows XP screen, and then it went blank (Black screen w/ a cursor). I can move the cursor around the screen but there is nothing to click on. I tried rebooting and the same thing happened, I have tried restarting in safe mode and still the same thing happens, and I have entered the BIOS (F12 during start-up?) and ran some kind of computer diagnostic which it said everything passed. Tried rebooting again and still the same problem. The computer seems to working fine, but everytime I get to the place where windows would ask me to put in my password the screen is black except for the cursor, or the safe mode message(when attempting to start in safe mode). Any suggestions? Thanks.
