Thanks folks
It's WinXP as it happens. Very slow to boot, and it seems to be something to do with the USB drives, as I am getting a "No Disc in the Drive" Message, whenit tries to 'auto-play' and set up the file system.
I have Windows updates switched to alert and I decide. It was about three days ago when I last updated Windows. Consequently, the Windows "version" I have now, is newer than the one on my disc! So it want's to do a full fomat and re install.
That wouldn't be a problem, but since I bought a new motherboard, I've been unable to get the new set-up to recognise 'A' drive, and there are some SATA driverswhich have to be installed at Windows main set-up, via the floppy drive. Consequently I can't get a full set-up to run properly, and I don't want to end up with nothing at all!
There was no 'repair' facility on the Windows disc that I could find. Oh for the days of Win 98, when you could just do a frsh install over the top, and not touch any other files. I was offered the chance to install Windows, but didn't want to risk getting so far, then having to format the disc.
So, it looks like I shall have to put everything over onto an external drive, and then get "Number One Son" to come over and do whatever it was he did last time, to set this lot up again!
Thanks again for the replies. In the meantme, if anyone has any knowledge of anti-malware programs and which is goodl I'd be obliged.
I use AVG Pro version antivirus, but that tells me there are no viruses.
I use CC cleaner, and that keeps asking for money to clean up what it finds. I suspect it just tells me it's found millions of errors. In the end I suppose I have to buy a proper cleaning program, but which ones do you trust?
Thanks agin folks.
