There is a problem with your RAM, motherboard, or video card.

my initial guess is a virus ......turn off system restore ...then go in to safe mode and run your uptodate anti virus programmes ......see if that clears it .....also possibly need to repair windows

I would suggest, from safe mode, you run a reallly good anti virus and also an anti spyware program.  You may have been infected with something.

If it does only during startup then its the BIOS setting that holds the key. But if it does quite often during your normal working, then a virus could be a culprit. Another reason could of some program which has been run from the drive and stopped adruptly and its still seeking its home from the background.

Could be hardware or software, Does it happen more often after your computer has been running for a while or just randomly? Is there anything that you do that makes it more likely to occur?

I haven't heard of anyone else experiencing this. You should do a scan for viruses or spyware that may be causing this.

Sounds like a program running n the background, go to start/run and type msconfig, when it opens look thru the list for that particular program and uncheck it, reboot.\ngood luck/

Probably because of an anti-virus program. Disable it before shutting down. Enable it again on startup.

Reinstall your software or just put your computer back to a restore point, this happens when you install new programs on your computer.

Something is running in the background.  when it does hit Ctrl, Alt and delete together to bring up your Windows Task Manager to see what is consuming your CPU and end the process of whatever it is.

Sound like your computer is running in the (safety mode) Try running your antivirus software to check for viruses as something is putting it in the safty mode.

Maybe you have been installed some video card drivers lately? Try System Restore.
