problem...
Running windows 7.
On some sites - some Pprune, Wilts and Glos Standard, even BBC. Not every time, but far too often to be acceptable, the computer locks up. Mouse doesn't work, up -down keys don't work, CTRL-ALT- DEL doesn't work. I have to switch off and start again from there and often, it then wants to do a 'Check Disc'. That takes about 5 minutes.
Any ideas about how to clear this other than getting my tame IT man in?
I may be an RF engineer, but I have no idea about anything digital!
