I am using a Lenovo G570 RAM: 4GB 1GB graphics. I am running Windows 7 64 bit

I installed a 4 bit RAM and it shows the same!

Recently my laptop starting acting weirdly. It starts to freeze even with some browsers open when I check my RAM meter... it shows 80-96% usage. I tried task manager and killing all the unwanted processes and services running, but that was of no use.

System Load

I tried scanning my computer for viruses but nothing showed up on Malware Bytes and Avast.

So, what do I do now to solve this problem other than formatting my hard drive? Is there any solution available?

Memory Usage

Open the task manager, switch to the Processes tab and list all processes by memory usage. That should show you which process is eating your RAM. –  terdon Sep 27 '12 at 17:42
    
it shows me firefox and chrome at the top of the list. each taking around 600,000K of memory. but with a ram of 4GB my laptop should be able to handle that right? @terdon –  Kiran Vemuri Sep 27 '12 at 17:44
    
Assuming you have a 64bit system installed yes. Still, something is wrong, neither browser should be using so much RAM. Please update your question with some more information. How much RAM does your computer report? Is it different from what you know to be installed? Is this a 64bit system? Maybe a screenshot of the running processes? Do you get the same behavior if you boot in safe mode? –  terdon Sep 27 '12 at 17:51

If you haven't already, you should probably run Malware Bytes or SpyBot S&D to make sure there isn't anything else (malware/spyware/adware) messing with your system. A free online scan at eSet just to make sure its clean might be a good idea. –  CharlieRB Sep 27 '12 at 18:29

Don't use FireFox. In my experience, the memory leaks in FireFox have made it unusable. If you have tabs open to pages that auto-update, like wsj.com or nytimes.com, my experience was that it only takes a day for the leaks to accumulate sufficiently to bring Windows to its knees. (This is on Win7 x64 on a Core i7 with 10GB.)

This is where Chrome really excels. In Chrome, each tab is a separate process, meaning the firewalling between pages effectively limits the memory leak problem. Try switching to Chrome (or one of the other major browsers) and see if that makes your problem go away.

I am parallelly using both the browsers! i use chrome because its fast and comfortable.. but crashes frequently. and firefox on the other hand is a bit slow but stable. –  Kiran Vemuri Sep 27 '12 at 19:40
