My computer, about 5-20 minutes after start up, slows down so much that I can hardly do anything for 5 minutes. I either A) wait it out till my computer goes back to running normally (takes 1-5 minutes) or hold my off button and restart (or actually shut down the normal way but it takes forever) but upon restarting the same thing happens again.
I have no idea whats causing this. When its happening I check my CPU usage and its nothing unusual (0-30%). I have scanned with Malwarebytes (nothing), Microsoft Security Essentials (nothing), and Superantispyware (deleted a few adware cookies). Besides this slow down period, I see no other symptoms of malware. The only weird thing is for some reason I always get PC Issue in the bottom right hand corner that says Windows Defender/MSE is off, and asks me to turn one of them on, but I already have MSE running. I click the issue and tell it to turn on and update MSE, after which it stops bugging me but it comes back at least sometimes after I restart.
The computer: a 2-3 year old dell laptop, been dropped a couple times but I've never had that cause problems before, windows 7.
