Hey guys I'm in need of help. As of this past Thursday my computer has been causing me a lot of problems. On Sunday I gave up trying to work with the immense lag and ran Spybot S&D. This found a few entries and removed them, I also used the immunize function or whatever it is called. Restarted my computer only to be greeted by the start-up repair. After many times of it looping because of Boot unable to find OS Load, I used the Dell Factory Image Reset tool, basically reformatting my entire hard drive. The problem continued even after I did this, so I ran a virus scan. Two minutes in my computer completely shuts off. I waited 30 mins and turned it back on. This time no sign of lag in my performance of high CPU usage. It was actually down to around 8-10%. Then I installed the 89 windows updates for my computer. While my computer was installing the updates during a restart, the computer completely shut off again. Turned it back on and it ran smoothly saying all updates had been installed. When I woke up the next day the computer had shut down. Turned it on and the lag was back. 100% CPU Usage with task manager using about 45-50, with everything else using at most 10%. I ran Adaware and my computer came up clean. I'm about to run another updated virus scan, but my real question is that I'm beginning to think it is a hardware problem, any ideas? - Also I have not installed any new hardware lately. Thanks for any help you guys may have.
