Hi, The last few days when I try to start my computer, nothing happens, I have to wait sometimes hours before it starts up. When it does eventually start, I get to the password page, and then it restarts itself over and over for about 5 mins. The 2 rom drives do a lot of clicking and flashing.

Any thoughts?

What is your operating system?
Can you get into Safe Mode?

If XP & you can get in:

You can turn off the feature that instructs XP to autostart on system
failure. Right click on My Computer and select Properties->Advanced
Tab->Startup & Recovery section->Settings button->uncheck "Automatically
restart" Apply. This will give you a blue screen with info on it and you
will have to manually restart the computer. The info might give you an idea
whether or not the problem is hardware or software related.

Do you have the installation CD for your operating system?
