Yes, I have done the complete diagnostics. I put in a new HD, and installed Win 7 professional, the problem was worse. So...I put the original HD in with a fresh install of Win 7 home edition. the computer seems to do ok while I am on it, no matter how long, but if it sits for an hour or more with no activity it will freeze, requiring a hard boot to get back on
the fans are working well, there is no sludge or dust ( I cleaned them first thing)
shall I put in safe mode and watch for awhile then?
that appears to be the case. this morning, after all updates installed and it rebooted, suddenly it shut off. I booted, and it came back with windows experienced a problem and had to shut down. check for solutions. of course it did not find one. After that boot, I went on to do something else. When I turned back to it, frozen. All day yesterday it did not freeze at all. Mind you, the whole problem began with the freezing before all the work I have recently put into it. I have ruled out hardware I am sure.
you will be on line for awhile? It is sitting in safe mode right now.
so far no freezing in safe mode with networking. I have had several tabs open and put it thru some paces. as much as one can do in safe mode.
