Computer was working fine and then it just crapped out. Running Windows XP. When I start it up, it flashes the Dell screen, and then it goes to a blank black screen with the cursor in the top left corner. If I do F12, I can bring up boot options and system diagnostics but that's all. No safe mode option. I was going to reload the operating system as there is nothing on the computer worth saving. I put the windows xp reinstall cd in and it says "Push any key to boot from cd.." and then it just hangs no matter what I push. What should my next step be, please! It's a work computer which we need to have operating if we can.
