My computer has been running well without any problems for months, then out of the blue, I can't get it started. On start up yesterday, a message flashed up saying something along the lines of " a registry fault has been detected but fixed successfully from memory" then a blue page flashed up for a fraction of a second, before the computer re-started itself. Every time I select a user on start up it now flashes this page and re-starts again. Its hard to read what it says, because its only there for half a second, but it starts off with "an error has been detected and the system is shutting down to protect itself. Non paged error. Start in safe mode etc"
Same happens if I try in safe mode/de-bugging mode. Tried windows repair, but it does not detect the SATA HDD, so it will not proceed.
If you can't get up to desk top in safe mode, I suggest you get yourself a copy of PC Check - downloadable if you can access a working PC or if needs be I can send you a copy on a Floppy. This is a boot device so you can boot to it and then run the tests, it checks HDD, MOBO, processor, memory and various other things. I suspect you may have developed a hard drive fault; if you have your OS on disc and can borrow a spare hard drive to prove it or otherwise I would do that - otherwise consider the PC check route.
