Windows 7: Computer Uses 100% CPU and Only 23% of Memory

Computer Uses 100% CPU and Only 23% of Memory

Hello all, I have a Acer Aspire 5253 laptop which came with a 1 GHz AMD C-50 dual core processor with 2 GB of RAM and a 64 bit OS. It was using 100% CPU and 90%- 100% memory, so I removed the 2 GB of RAM and installed (2) 4GB RAM. Thing is it will still using 100% of the CPU and now only 23% of the memory. Is there something wrong here? 1-2 apps running (this number includes the anti-virus program) and one loading can stall or freeze the computer. Why so little memory usage? why doesn't the CPU allocate more memory to help itself with the load?

Programs mostly used:
Google Chrome
Windows Office
iTunes
Kaspersky Pure (anti virus program, always running)
Pot Player (video player)

open the task manager cntl+alt+del
and find out what application is eating all the cpu time.
It shouldn't be running at 100% all the time, even if you have a slow processor.
Usually I blame antiviruses first in stuff like this.

As Mag has said, something is defenitly running. Do you have an automatic defrag program ?

It's not 100% usage 24/7, but stuff like running Chrome and starting up iTunes or Office can stall the computer and/or the program loading. With the web browser and Task manager running and anti-virus programs running (7% CPU usage), opening performance monitor brings it up to 100% CPU usage and 26% memory usage or a little over 2 GB of memory. Any program that loads uses 100% CPU and may use it for quite some time after its opened.

Windows 7 should not hang even in a situation where you update the RAM get considerably beyond the CPU specs.

Is this a factory preinstall which you haven't yet Clean up factory bloatware or better yet gotten the much superior Clean Reinstall Windows 7 Factory OEM?

These steps can make a huge difference since the typical bloated factory preinstall is corruption in itself of Windows 7. I would at the minimum get a Clean Boot right away and run free lean Microsoft Security Essentials which provides adequate protection without the bloat you pay for in AV 's.

When it comes to bloatware, I removed them already, Norton was the hardest to get rid of with all of the stuff not uninstalled when you do a uninstall. Did a search on my hard drive and found stuff in odd places.

Did you follow the additional steps in Clean up factory bloatware to run SFC -SCANNOW Command to see if bloatware uninstalls damaged System files, and if so if they are unfixable after several scans, did you consider a Repair Install.

If in your position however after uninstalling monster bloatware like Norton and/or Office trial I have performance hangs then if causes aren't revealed in these troubleshooting steps I would get the vastly superior Clean Reinstall Windows 7 Factory OEM.

I'll try these steps when I finish with my company work (using PowerPoint, Exel and word ATM) while posting this. Want to make sure nothing goes wrong right now. I'll get back on when done and relay the results. THX
