    Thanks heaps for your info.

    Finally got into the CMOS screen and went to safe mode.I did a system restore using date a few days before the problem showed up. This was sucessful, and all now OK.

This isn't a bios problem, this is an operating system problem, and most likely a hard drive problem. Do a system repair with your restore or operating system disc. If the repair doesn't take, the reformat the hard drive using a full NTFS format, not the quick format, and install a new operating system. If the drive will not format, or you have any issues during or after the format and install, then the hard drive has failed and will need replaced.

I have a presario c500 that comes up to the f10 and esc screen upon booting, and then will go blank and continue to loop though the screen again and again. I have removed the battery and held the power...


It is your operating system that is failing, not your hardware. When Windows hits a Blue Screen of Death on startup it happens so fast that you only see it for a split second then it reboots. If you want to know what the issue is, when it reboots wait till the first screen goes away, (the f10 and esc screen you mentioned) then start tapping F8 every few seconds. It will bring up a new menu that has options like Safe Mode, Safe Mode with Networking, etc. Choose "Disable Automatic Restart on System Failure" then hit enter. Windows will continue to boot and then will stop on the Blue Screen of Death. Copy down the info on the screen and enter it into a Google search or post on here for me to diagnose. Let me know if you need more help.
