Could be conflicting pgms or even registry errors. Run CCleaner and do the Clean and Registry both. It may take more than one pass if your system is garbaged up pretty bad. http/www.piriform.com/ccleaner
If it is still in new condition with tons of bloatware and ad-ware, run Malwarebytes too.
Better yet, uninstall as much bloatware crap as you can.
Im not really sure, I think system factory recovery.. Im not sure.. Its awhile ago.
If you did a system recovery and are left with just as many problems, then you may need to reformat the drive and reinstall Windows. If you did a system restore and were left with problems, then try a factory recovery.
Do you remember what you had to do to do this recovery?
The beeping sound is not a good sign. It makes me wonder if it's an indication of hardware failure.
You may want to consider a system factory recovery, if you haven't done that. If you used a system restore point, that's not the same and the factory recovery is more likely to rid you of software problems. Only issue: a factory recovery removes all data and installed programs, so back up your data first!
Also, if you can get your hands on a can of compressed air or an air compressor, then use that to blow out the vents thoroughly.
