When running Firefox, sometimes it doesn't start up and a window that has something to do with scripts pops up. Choosing "Yes" on the question "Do you want to continue using this script anyway?" will start Firefox and choosing "No" closes the window and running Firefox again works as well. Running Internet Explorer 8 takes a really long time to load pages (which isn't the case before) so I don't even use it at the moment.
When I look at the processes of my task manager the system idle process (system), which is only taking up 28K memory usage, has the CPU value oscillating in the mid to high 90s. In the processes tab, CPU usage is around 90-100% most of the time. Consequently, other programs that I use often such as VLC for viewing videos and various games have deteriorated in function slightly as well. Still, after a while, these programs become tolerable to work with and doesn't cause much of a frustration. However, I can't say the same for other high performance programs, especially games currently installed in my computer.
This poor performance problem started happening after I got the following blue screen error from running GMER as part of the preparation for Malware Removal about a month and a half ago. It happened twice because I ran GMER twice (thinking it probably was just a one-time error) and yielded the same result.
A problem has been detected and Windows has been shut down to prevent further damage to your computer.
If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps:
Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any windows updates you might need.
If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

I'm guessing that some components of the system have been damaged due to this error. The only new programs I've installed from that time to present are Secunia PSI and Registry Booster to protect my computer from exploitable vulnerabilities. I have run McAfee anti-virus and Malwarebytes on a regular basis and the system is clear of any threats. I'm inclined to think that the performance issue has something to do with damaged components.
Is there a solution I can explore to mitigate the effects of this poor performance issue?
