Sudden peak memory usage and lock up

post #1 of 6
Thread Starter 
Hey peeps,

I'd like to tell you a very weird problem i'm having recently. Sometimes my sigrig stops responding and when i check the task manager, i see that memory usage is like 5,75GB (Total ram=6gb). The weird thing is that under the processes tab there are no applications appear to be using that amount of space in the memory. According to the processes tab there should be maximum 1,5-2GB of usage at most. Also i'm observing very heavy hdd usage when this happens. This is probably a sign that whatever is taking so much space in the memory, uses the virtual memory as well...

What is causing this and why can't i see which program is using that much of space in memory?

Thanks in advance...

I have avast running in the background 7/24. I guess its "realtime check" feature is providing enough protection.

Sounds like a software issue, have you installed anything new recently?

Just because it has real time prevention doesn't mean anything can't get through.

I'd still run a virus scan.

It could be a memory leak with a background process. Also this happens when transferring files over a network.
