I run on 7 home premium 64bit 6gb ram and lately, my physical memory usage has skyrocketed to 99% for an unknown reason and my laptop is now unbelievably slow... It started out about a week ago and I haven't changed anything in my computer for this to happen(at least not that I can think of). I tried to find the answer on the net, but nothing. I ran a full scan with Kaspersky internet security 2011, malwarebytes' Anti-Malware, Ccleaner, speedupmyPC, but apart from cookies and temporary internet files, nothing was wrong. Tried to kill a few processes here and there but before I break anything I want to have a second opinion
Here are some screenshots of ressource monitor and process exp.
Thanks for your help
p.s. sorry for that french writing if you need me to translate anything just ask
