Try cleaning your system of resource wasting crap and registry errors. Run CCleaner and do the Clean and Registry both. You may have to run it untill it doesn't find any more crap.
http://www.piriform.com/CCLEANER I've found that a lot of those kind of issues can be solved by cleaning one's system.

If the problem still exists, check your memory with Memtest: http://www.memtest.org/
Run at least 1 full pass on each stick individually inserted in the first slot.

Another issue could be graphic driver related. Try running Driver Sweeper. Uninstall the graphic driver, reboot to Safe Mode, and run DS. Have it remove any Nvidia, AMD, and ATI graphic driver remnants it finds. Reboot and install the latest driver for your card and O/S.

How long ago did you build this computer?

It sounds malware related. Do you have an efficient antivirus installed?

I recommend you download the following program, install it, update it, then run a full scan.

http://www.malwarebytes.org/

Afterwards, if anything is detected, select display/show results and then remove the malware.

If the above occurs, you may need a better antivirus. In which case, I recommend you completely uninstall your current antivirus (if any) and download and install this one...

Same wash, rinse and repeat routine as the malwarebytes program. Download, install, update and run a full system scan.
