Hi Guys,

My W7 Ultimate machine has virtually stopped working. My CPU usage is less than 5% but the Memory (4GB) is at 90+% usage with nothing running that I can detect. However, I can hear the machine "working" with no processes functioning.

I tried System Restore with no luck. I also did a Memory Check with no issues reported.

I also tried to run MBAM but could not start it.

Thanks.....

Hey Terry - The symptoms you describe would normally be caused by either memory leaks or malware - not being able to start MBAM indicates it may well be the latter.

Have you tried running a scan through your resident AV?

Alternatives would be to download one of the AV rescue discs and boot direct from the disk to perform a scan, or try one of the online scanners such as Eset or TrendMicro House Call.

From what you have described, the most likely suspect would be malware. I'd advise you to eliminate that as a possible cause before looking elsewhere.

Cheers... Jim

Jim,

I was finally able to do a complete MBAM scan with no problems detected. I also ran Ad-Aware with no issues...

Will I be heading to the Memory Store ?????????

LOL. No mate. Sounds like it might be either a software conflict or a program leaking memory then. What security programs do you have installed? Have you installed any new ones lately?

Open Task Manager, go to the 'Processes' tab and click on the option to "Show processes from all users". Click at the top of the "Memory" column so numbers are displayed descending (highest at the top). Can you see anything there which is utilizing a lot of memory? Post a list of the top 3 or 4 and corresponding numbers if you wish.

Cheers... Jim

Here ya' go:

svchost.exe - 24,000k there are at least 10 of these using 50-60,000k

Search Index 8,000k

csrss.exe 7,000k

 

I don't recall installing any new items other that a web cam a couple of monthes ago.

I use AVG & Threatfire for a long time.

Is that 50-60,000k each or total?

Well that's about normal then, certainly nothing over the top.

Try disabling AVG for a time and see what happens. Should be an option in the right click menu to temporarily suspend real time protection, or turn off altogether. Don't use your browser during that time, just navigate around and see if RAM usage drops and it is any quicker. If not, do the same with Threatfire.

If still no joy, open a Run dialogue box (Windows key + R key), type msconfig into the dialogue box and then hit OK or the Enter key. Go to the Startup tab and post a screenshot of the list.

Then, still in msconfig, go to the Services tab and click on Hide all Microsoft services. Include a screenshot of that list too.

Something is using more RAM than it should, we need to find out what. As I said mate, it will generally be caused by malware, software conflicts, or memory leaks. Seems, after your responses, malware and memory leaks are not likely so some sort of software conflict is next on the list, and security software is the usual suspect.
