My computer would occasionally freeze but my mouse would still work. Mouse would still move and click but the application and computer will have no response to it. Ctrl+Alt+Del, Alt+F4, Ctrl+Shift+ESC will have no effect when it freeze. There is no specific application that freeze my computer. It will freeze when I'm using Firefox, IE, or just watching a movie. The time are random as I have gone 4 hours straight without freezing when downloading files. It does seem like it has a higher chance to freeze up when I use more memory intensive application.
When it started:
Started this Tuesday July 14, I was in the process of updating Malwarebytes' Anti-Malware and I opened a window that cause several pop ups. I closed all the windows and then after a few seconds the computer freeze. At the time, Malwarebytes was just about to install the updated client and was in the middle of it but it freeze along with my computer. After I hard boot the computer back on, I started to use Firefox to contine to browse the internet but after a few minutes it will freeze again.
What I have tried:
I have reinstall Malwarebytes' Anti-Malware after the fail update and ran a scan to clean my computer. I have also use SuperAntiSpyware to clean my computer. I've use the Eset Online Scanner and Symantec online scanner to check for virus.
Then I uninstall Firefox and Malwarebytes' Anti-Malware and still I have the problem. I went to Windows Update to get all the essential updates, upgrade IE from 6.0 to 8.0, and defrag my hard drive using Diskkeeper. I scan my HD with HDTune, repair registry with Advanced System Care, and finally use System Restore to go back to July 10th.
Then to check for hardware problems, I used Dell's Diagnostic Tool at boot up to test my hardware component and they all passed.
Could anyone help me figure out if it is a malware/virus that is causing it to freeze or is it something else? I would greatly appreciate all of your help.
