Okay, long backstory short--a few weeks ago, I was on another thread with these same problems.
A moderator helped me and walked me thru a bunch of virus stuff. Computer came up clean. BUT...I'm still having issues, and he suggested I come over here to these boards for help.
Here's the jest of what's happening.....
A few different items....
(a) Programs just won't open sometimes (i.e., calculator, calendar, lightroom, irfanview, etc.). Once one won't open, none of them will. Happens randomly, not consistently but enough times to be a problem.
In order to correct the problem, I have to shut down the computer. Well, guess what? Task Manager won't open, and the restart option won't work either! So, I have to manually hold the power button down until the entire thing powers down and the reboot. Of course, after the reboot, everything works (until the next time this happens)!
Sometimes, upon start-up, things take FOREVER to process and load in. I try to go thru my Start-Up items frequent, but now, it's just getting ridiculous. It's taking MUCH longer than it should to restart the machine.
I can't figure out what's going on. It's not virus/malware/spyware etc., so I'm thinking it has to be operating system related.
Any ideas on where to start?
