Yes, had it in jumpered as both master and slave, same result, likewise on the primary IDE, when I think about it this problem has prolly been around for a while, I keep a second hard drive outside the machine and bung it in as slave to copy stuff I want to back up from the master occasionaly,last time I tried this it was acting up I could not get the bios to recognise the second disc which it had done no pobs before.
Normaly I would just format the hard disc and do a clean windows install, sods law mate of mine has got my graphic card sound card and modem driver discs.
