1) Programs quit responding. Can sometimes open new windows.
2) Existing windows quit updating. System clock quits updating.
3) Hard drive activity ceases.
4) Tried system restore, running Anti-Virus
5) MalwareBytes and AVG command line show clean.
6) One things freeze, the mouse usually still works and can still click on the start menu, and right click on things for options... they just don't do anything.
7) Freezes can occur between 7minutes and 2 hours into working on the system.
I run a Dell Precision M4300 as my work computer. It has Windows XP x32 SP2 on it.
On Tuesday I ran into the Ransomware "AntiVirus Soft". I printed out and followed the instructions from here, and that worked great. It was late when I finished, so I shut my computer down and was working with it yesterday at the office. It kept freezing up on me. The freezes were weird.
For instance, I would be multi-tasking (I do tech support for a program called SolidWorks, yet that doesn't always help with general computer support), so I would have SolidWorks open along with my e-mail, and internet browser (with multiple tabs for various work related pages). What would happen is I would try switching tabs in Firefox and it would hang up... the mouse would keep moving. I could select and alt-tab between windows, and they would quit responding. I could right click on the taskbar and choose "Task Manager" and it wouldn't come up. I could also Ctrl-Alt-Del and choose task manager and then I'd be stuck looking at my desktop and nothing else. Eventually I have to hard kill the power (i.e. hold the power button for 5-10 seconds).
Sometimes, when it starts behaving like this, dragging a window will cause the mouse to lock up and then I can't see/do anything on the system at all.
I re-ran MalwareBytes and it found nothing. I tried running my Anti-Virus in SafeMode, yet it can't run in safe mode (Trend Micro). I downloaded AVG and it could run in command prompt mode in Safe mode and that found nothing. Everytime I try logging into the computer normally and run AVG it has locked up at somepoint during the run. The system clock stops updating, the AVG window stops updating, but the mouse still moves.
I tried running 2 system restores yesterday. 1 from Monday and 1 from Friday, and both failed because nothing had changed. I booted the computer up at 10:13 last night and brought up the system clock. When I came downstairs today, the clock was frozen at 10:20:17. My AIM had new mail notifications on the screen (that usually disappear after 5 seconds or so). I could still click on the link to pull up my e-mail, but the pages would not load other than the window outline, nor would they go away if I tried closing them.
Also, a few times when I had the Task Manager open when it froze, it would let me still sort the processes. When I sorted it by CPU usage both A-Z and Z-A sorting, all the usages showed 0. When I sorted it Alphabetically, things that should've been on there, weren't. (i.e. System Idle time). Because of this, I'm thinking anything that had CPU usage disappeared from the list.
Current AVG just stopped, hard drive sound died, mouse still moves. Went to Start, Right clicked on my Computer, and selected "Manage". It had some hard drive sound, but the Manage window never showed up, and the corner of the Start Menu is still being shown on the AVG window. This was the first time I tried logging into the computer itself (which as a different profile than the one I use to sign into my work domain).
Could this be hardware related?
Could this be tied into the Antivirus Soft issue?
Edit: Does this belong in the anti-virus section?
