Like I said, could be a million things. That being said the CPU is the last thing that would go bad.
The most obvious thing I'd choose would be that it's overheating. Seeing as 50% of whenever anyone asks me why their computer is running slow/weird, that's the problem. (The others being improper/not done matiness, then the powersupply, then the GPU, then the HDD, and then everything else.)
If you want you can test this by running a CPU stressing program while having a tempature monitoiring program open.
Core Temp for tempature
IntelBurnTest or Prime95 for stressing (granted IntelBurnTest runs the CPU at 110% and up to 22°C higher.)
Running them for ten minutes (20 for prime) should be enough to see if it over heats. The max temp for the 4770 is 98°C, the max tempature Intel reccomends is 72.72°C, and anything over 80°C will proably damage it over time. IntelBurnTest also spits out a Gflops number, and we can compare this number to other 4770's that have run the test to see if it's up to par in performance.
Still, could be one of a million things. None of us could really know for sure unless we could physically look at it and test all the parts for a few days OR tell you to run millions of differnt tests for the next couple of weeks that you may-or-may-not be computer savy enough to even do your self- so that's never going to happen.
I wouldn't even bother with running the tempature test and just make sure the heatsink inside the computer isn't clogged with dust, and if it is, just use canned air to blow it out without taking it off. If it's not that, then everything else it could be isn't worth your time to ask you to check.

99% of the time, I edit for type-o's and grammar. I'll note it if that's not the case.
I write near essays for most my responses, and then try to condense as best I can to the introduction of one. Less is more. Let me know if I post to much.
I do a lot of spacing for readability. Let me know if that makes my posts seem to big.
