Time to do the basics
Go to www.filehippo.com, download Malwarebytes, go to CUSTOM Scan and set it to do a full system scan (by DEFAULT IT DOESN"T DO THAT, and AntiVirus doesn't pick up alot of malware) - this resolved almost ALL other similiar posts to date as most had Malware the AV didn't pick up.
Remove whatever AV your using and download AVIRA, AVG, Comodo or Panda go to CUSTOM Scan and set it to do a full system scan (by DEFAULT IT DOESN"T DO THAT) - this repeatedly has resolved alot of people issue relying on MS Essentials.
Repeat the AV/Malware scans till the system comes up clean.
Did you install all Windows Updates? Including OPTIONAL except BING? Check them and repeat till ALL are installed.
Download and run Slim Drivers, install all the latest updates but you don't need to reboot until you do the last update
Download and run SPECCY, copy and paste the first tab to show your idle temps
Download AUTORUNS and turn off anything NOT critical on startup, so you don't need to run JAVAScheduler to check for Java updates everytime you start your computer for example. BE CAREFUL AND KNOW WHAT YOUR TURNING OFF BEFORE YOU DO IT.
Go through and provide a response on each point, don't SKIP IT because "I ALREADY DID IT" , just try doing it again as of THIS post so we know NOW what is happening as compared to BEFORE you posted.
