Extemely headache problems suspecting faulty southbridge

Hi, i have this laptop(Dv6-6003tx) soon to be 2 years old and it has been giving me hell lot of problems lately. During jan this year i accidentally spilled some liquid on the keyboard and i immediately force shut down and placed the laptop to dry before using it again. I don't know if the spill might be directly related because what confuses me is that it took 2 months for the consequences to take effect. Anyway here are the problems.

1)All was well until end of march where by whenever i run any intensive task, my default browsers will open itself at insane rates. The more i try to close it, the more it will open.
2)One long chain of beeping sounds on start up. Sometimes i have to remove the battery and just use the power adapter all is well. However, if the battery is not on the laptop and there is beeping sound on start up, i have to put it back in, remove the power adapter and it will boot.
3)Very loose USB. My mouse will keep getting disconnected once in a while
4)When computer successfully boots, my touch pad will only respond until i hit enter key. However, if i'm using my mouse it will be ok to move without hitting the enter key
5)Number 2 key would randomly spam itself until i hit the number 2 key itself again. Also my qwer stopped working all of a sudden.
6)Temperatures are around 60degree when i'm surfing net and stuff but if i'm watching videos, they can go up to 75.
7)And the most ironic of all, once i get the system to boot, it will not have any freeze or bsod it will work perfectly until i shut it down again.
8) Missing battery and volume icons at taskbar.
8)Choppy lags that i had disable my graphic card and just use the intel chipset

Things i have done:
1)Reformatted at least thrice
2)Removed keyboard and the beeping sound still remains
3)Perform stress test and seconds into the testing, browsers would start opening at insane rates causing cpu usage to go up to 100%.

It's like i'm getting some new problems everyday. So yea, these are the problems that i can currently remember. I'm posting this to seek your opinions on what faulty parts there might be. Thanks in advance.

What was the liquid that was spilled into the keyboard?

Drinks with a high sugar content (that includes wine and hard alcohol) can leave a thin film or crystals behind when it dries. The crystals can be conductive and this could be causing weak short circuits on the motherboard. That may explain what you are seeing.

The solution in that case would be to completely disassemble the laptop and thoroughly clean all the parts. Not an easy job, and above the skill level of most home users. If that is the case you could take it to a shop.

Ribena! Had to look that one up!

Are you going to attempt cleaning it yourself?

Haha. Probably not, i'm just really depressed being haunted by all these problems. But till date, i still have no clue what causes the main problem which is whenever i run any intensive task even stuff like full system virus scans, the browsers would open themselves at insane rates.

What do the scans reveal? Anything?

You referring to virus scans? If so, i already did like a ton of scans all over and no threats were found and on top of that i literally have reformatted more than 3 times. The most recent reformat that i had, i booted the computer, downloaded and installed windows updates. Did a full system antivirus scan and left it there while downloading a game too. So basically i haven't installed anything and had 2 tasks running and yea when i came back my IE was opened like 10 over pages. The ironic thing is that yes it will spam but it will come to a stop after like 5mins? and the more you close it the more it retaliates.
So if i am in a game, i will have no choice but to terminal my session. Really weird problem.
