Tested the power supply unit with multi meter all voltages are OK
Removed CMOS battery and replaced with new battery
Replaced the graphics card and connected the HDD and the DVD/CD ROM
The pc powered on and could hear the beep as normal, had the message Diskette drive 0 seek failure, went into the BIOS disabled the Floppy A [1.44, 3.5 in.]
Set the BOOT device priority to;
First Hard Disk
Second CD ROM
Fourth Hard Disk although there isn’t a fourth HDD
I am confused as on the HDD Group Boot Priority it states “1 3rd Master: WDC WD5000AAKS-75YGA0 which is my only HDD installed with Windows plus data and applications.
The problem I have now is that the BOOT sequence goes into a loop and does not load Windows but instead after each loop the screen shows that there is NO SIGNAL and the pc starts again and the splash screen displays but the pc goes into the same loop over and over again with no other message.
Any help with sorting this endless loop and getting the pc to load Windows would be most appreciated.
I have now sorted the boot loop by doing a Windows Repair with the installation disc and restoring to the last working restore point and replacing the SATA data cable to the HDD. Don't know whether replacing the data cable or restoring to the last working restore point did the trick but who cares the pc is now working again.
