Windows 7 running at 80-97% Physical Memory when doing nothing.

I have a system running Windows 7 Ultimate 64 that was previously running fine (besides problems with wifi I didn't have with XP Pro), but suddenly last night it began running in at 80-97% Physical Memory Usage.

The task manager can only account for between 5-10% of the memory. My CPU Usage rests at 0-10% which is what it was before this problem began.

The computer specs:
*AMD Athlon 64 Processor 3800+ 2.39 GHz
*2.00 GB (1.87 GB Usable)
*NVIDIA GeForce 8400 GS

I didn't do anything special to it last night, just was listening to music on Pandora and was going to play UT3. The problem may have started when I tried opening UT3, I stupidly didn't think about that till now and now I'm not sure if that is when the problem began. :-/

Hi Reaver,

 

 

Welcome to Microsoft Answers!

 

Check what are the processes running in the Task manager and which one of it is using the highest memory.

 

Also check if the Indexing or disk defragment services are running, as at times when the system is idle they try to use the physical memory.

 

This could also be an issue with virus or malware, perform a scan on the computer.

Follow the given link which talks about the malware and virus scan.

You may also try performing a system restore to a when the system was working fine.

To restore the operating system to an earlier point in time, follow these steps:

1.         Click Start, type system restore in the Start Search box, and then click System Restore in the Programs list.

If you are prompted for an administrator password or confirmation, type your password or click Continue.

2.         In the System Restore dialog box, click Choose a different restore point, and then click ‘Next’.

3.         In the list of restore points, click a restore point that was created before you began to experience the issue, and then click ‘Next’.

4.         Click Finish

 

Note: When you perform System Restore to restore the computer to previous state, programs and updates you installed are removed.
