It use to randomly restart on occasion but now it is doing it constantly to the point it won't boot-up past the Windows start-up screen.

It does not respond to the F8 key, so I can't start it in safe mode. I can get into the set-up screen but no changes seem to help because it just reboots and then resets the settings I changed.

Any ideas? Thanks much.

this could indicate dust buildup or hardware finally gone totally bad ,so start with opening up and cleaning dust buildup, tools to use are a paint brush and a vacum,give it a try and see what happens

Thanks, that was the first thing I tried. I thought maybe it was overheating but to no avail. Without being able to boot-up I can't diagnose the problem. I guess it is time for a new machine.

if you have the windows disk you could try booting to and going into the recovery console and doing a "chkdsk /r" at the prompt

I tried with a cd but it doesn't respond to my keyboard commands and loads with the hard drive instead of the cd. I'll have to check if I have a windows disk. Gosh, I haven't used a disk in years! Thanks again for your help.

are you using a usb keyboard or a ps/2 one ,if usb ,maybe you could try a ps/2 keyboard and see if it works

I only have usb and wireless keyboards-no ps/2.
It's funny that the keyboard responds at start up to the del key to enter set up and works in that screen responding to commands. When I instead try F8 (to enter safe mode) it does not respond and as I said it does not respond to commands when I try to boot from cd-weird huh?

Have you recently installed ram? Faulty Ram or wrong Ram type usually is the cause to this problem.
