Awful i7 3770 Performance

Had completely fine performance, then this morning my PC just locked up, bit weird, restarted the machine, failed to boot, needed to clean up the insides so thought sod it so removed a few pieces, gave them a dusting and replace, next boot it worked, and it seemed to be fine.

Using the machine for a bit and noticed horrendous CPU performance, things that would never even stress the machine before were now putting it to 100% cpu usage.

Googling seems to suggest my core voltage may be a bit low? but idk.

Watching a 720p youtube video.

Core speed will still get up to the mid-2k's/3k's but it seems incredibly unpredictable, highest I've seen the multiplier get to is 25, lowest 8, I really don't know enough about actual problem diagnosis, any idea as to what could all of a sudden be causing such awful performance?

Any software changes?
Sudden loss of power?
cpu temp in bios?
cpu voltage in bios?
Any hit or fall of something on the case?
water ?
Did the cpu cooler move from its place ?
Your pic shows vcore at lowest value at speedster. What's vcore at load ?

No software changes or sudden loss of power. did have a rather embarrassing run in with a bit of water last week, every got immediately removed and dried, and left, seems to of been fine since landed on the mobo not any components. Case did get hit earlier thinking on it, which reminded me the heatsink is damaged after removing components last week (a new one is on order) checking temps I was about the 90degrees mark, guessing the damaged heatsink has taking effect. Could it be cpu is being throttled due to temp? Can't get bios voltage as not at home atm.

3/4 Pins that hold in into the board were broke so while it's still against the cpu it is no where near flush. I also removed the cpu to check it and don't have any thermal paste to re apply. Compound this with the fact it's a stock heatsink.
