Sealracer, it's not a case of having to start all over again, this will end up being the most simplest of solutions ever. All that's happening is as follows:- Open up ANYTHING & it opens fast & low CPU usage, no problems. Then open anything else & it's 100% cpu usage & hardware interrupts, really slow & sometimes even doesn't respond at all. But, if i then start again & open the same programs or even similar programs, ie, Winamp with Word, Media Player with Access, Calculator & connecting to the internet etc, then everything is OK. If i kept the computer on for 2 weeks & opened every possible combination of programs 2 at a time then everything would work completely normally. It's only when i ask the puter to do 2 things for the very 1st time from switching on that the problem shows.
