The past three days, it's happened about twice a day to me. Just at seemingly random times, my currently running programs stop working and attempting to open new programs just results in the program's icon being momentarily highlighted in the taskbar, and then it disappears, as if the program automatically closed itself. This even works for simple programs like Notepad or Paint. Any currently running programs usually crash or stop working. All of my tabs in Chrome will have the pages using Shockwave crash, and attempting to open any new tabs or navigate to new pages will just result in a white screen. The computer is fast and responsive on the desktop (ie, I can open and close the start menu and highlight programs on my desktop with a mouse rollover), and nothing on my computer is frozen, just not working.
This all happens just at one single moment when everything stops working right, and I have to manually shut down the computer, because going through Windows to shut down or log off does not result in anything. Upon startup, everything is back to normal. CTRL+ALT+DEL command results in a black screen with the cursor visible, but nothing happens.
I was recently infected with quite a bit of malware, but as far as I know, I got it all off. I don't know if this is was "malware" or just my computer being a bleep. What do you guys think?
