This is my secondary computer that I use mainly to edit and do some internet usage. It is a dell Dimension 3000 that I have had up and running for about 4 months after upgrading the ram to 2gb and installing a new 120gb hdd with Win 7 Pro (which has 79.5 gb free space). It performed really well for a long time but then started bogging down to the point that it is actually too slow to use much.
The performance tab in task manager with computer idling and nothing open shows usage from 50% percent to 100% most of the time. Occasionally the usage might drop down to 6 to 15% for a second. I am running avast free and malwarebytes free.
If someone can help and needs more information, please advise.
Thanks,
JohnGo
