I have recently experienced a problem whereby my system closed down without warning and when I tried to re-boot the BIOS could not locate the Hard Drive. I have now replaced the Hard Drive and have managed to install Windows XP, but the problem has now returned. Sometimes it boots just past the Welcome Screen and than a very quick blue screen (Unable to read - as gone rather quickly), and other times the hard disk cannot be found.
Could this be the CMOS Battery or a corrupt BIOS. If CMOS Battery how do I access it to replace.
Any help would be great.
