Since Tuesday, 2/1/07 I have been getting a blank screen on start up then when I restart my system I have been getting a Phoenix Award BIOS Screen with a list of installed components and a warning message that the system is in safe mode, that I should reset the CPU or memory frequency in the CMOS set up and that I should press F1 to continue or Del to enter set up. Pressinf Del leaves me with a blank screen and a flashing cursor but no access to the BIOS. Pressing F1 enters the XP system and the PC started up. The following information was shown below the warning - 01/09/2006-C19-W83627-6A61EA1AC-13 This message and procedure has been evident since on start up but as I was unable to enter the BIOS there was little I could do to resolve the situation. On 5/1/07 using the XP recovery console I rolled back to 26/12/06. The problem still existed and on 6/1/07 I cleared the CMOS memory. Now the system will not go into the BIOS start up and when I switch off the power the system powers off immediately. Any help would be appreciated.
