|OK, I did that and the blue screen of death shows:|
UNMOUNTABLE_BOOT_VOLUME, with the technical information:
***STOP: 0x000000ED (0X8B29BC28, 0xC0000006, 0x00000000, 0x00000000)
I am going to shut that computer down now, check the memory modules but according to the BIOS setup says both are being seen. I will post back in a minute or two.
Thanks for your help so far.
