While we're on the speeding things up page, here's a little tip:
Diskdefragmentation is a good thing to do.
Its built into windows but i was suggested Defragler (by piriform, which also made ccleaner) by an IT guy once.
I regulary run Ccleaner and Defragler and my old pc outran all my old classmates (we had the same pc) and my current pc outruns all my classmates pc (again, same pc, its just that i care more for mine).
If you work with you're pc you could run a ccleaner-defragler-combo on each sunday night and it will be ready to go on monday!
Back to your problem!
I would maybe get a malwarebytes trial and check for possible spyware and computer-crap...
Run a antivirus scan, maybe. Just to see if you have crap that f's stuff up.
Why do you have to reboot?
I really ain't sure what the issue is... but we'll try to help as much as possible!
