When you say the computer is unresponsive, is the mouse still able to move? I ask this because if the mouse also freezes it may mean a running program is using up all your memory leaving everything at a standstill until the coding is finished being read.
This could be caused by bad registry entrys, bad drivers for a program that may be conflicting with your computers hardware, or even a virus or trojan of some sort that is trying to access the internet to send data to another computer.
If you can move the mouse.
You can use Task Manager to display a list of the programs that are currently running on your computer. If a program seems frozen, or does not appear to be responding, use Task Manager to view the status of the program.
1. Open Task Manager by right-clicking the taskbar and then clicking Task Manager.
2. Click the Applications tab to see a list of all the programs that are currently running on your computer and each program's status (either Running or Not Responding).
3. If a program is not responding and you want to close the program, click the program, and then click End Task. Any unsaved changes made using the program will be lost.
You can also open Task Manager by pressing CTRL+SHIFT+ESC.
________________________________
Identify the process associated with a program
The programs that you run on your computer have processes associated with them that start the program. If a program stops responding, knowing which process is associated with the program can help you troubleshoot problems. For example, if a program isn't responding, once you know which process the program uses, you can end that process to exit the program that isn't responding.
1. Open Task Manager by right-clicking the taskbar and then clicking Task Manager.
2. Click the Applications tab, right-click the program that you want to identify the process for, and then click Go To Process. The process associated with the program is highlighted on the Processes tab.
To view more information about any process running in Task Manager, right-click the process, and then click Properties. In the Properties dialog box, you can view information about the process, including the location and size. Click the Details tab to view detailed information about the process.
Please add the processes and programs that are running the processes here so i can look further into what is causing this problem.
