[SOLVED] I lost ~100 FPS in a night

[UY Scuti]

Hi everybody,

first of all I have a MSI GE73vr 7RE laptop ( sh**box ) specs are : i7 -7700HQ, gtx 1060 and 16gb ( originally 8 ) ddr4 ram.

So , long story short this laptop have been a good source of trouble since i buyed it 3 years ago, first i had to completely REMOVE the speakers they were making a constant buzzing noise. Then one of the hinges maintaining the screen decided to quit and just literally ripped itself off the screen cover.

Appart from this, it have been pretty good in terms of performance, no big issues on hardware or software.

Here we go : 3 days ago I was playing on the computer and the second hinge decided it was its time too and my screen just dropped down from the hinge to my desk ( an horrible 2cm fall ) , and this was enough to shut the screen off wich i wasnt expecting at all, it made me jump and i litteraly ( i wish i took a picture) dropped 2 drops of coffee on the upper right of the keyboard, where the on/off switch is.

The screen is partially broken ( half of it have a white glaze ) and the keyboard also have half of it not working ( but not half/half , like random keys )

I plugged my pc to an old first gen flatscreen with a hdmi adapter. After adjusting the resolution to something ok i test some games, League of legends is pretty disturbing but i have around 120 fps at max specs, later I tried Valorant, no fps issues, game was rly smooth.
And then yesterday suddenly i have 20 fps max on League of lengend and doing 5-->20-->5-->20 non stop. and Valorant is telling me " low client fps " and yeah i can see that ...

Last thing , i did a benchmark with novabench around a week ago , i had a score of 1975, i tried this morning and i had 787, and all cpu, ram, gpu and disk score have dropped.

In my mind the coffe related problem wouldn't have poped 3 days after, but well, my knowledge on this is pretty limited, HELP ME .

( I had no downloads or any update in this period of time. )

Thanks if you read all 😉

Mighht be liquid damage causing problems in some part of the motherboard or example keyboard , this can manifest after few days this is normal.

Cant beleive you booted it up after all this, first thing to do usually is plug off power cable and remove internal battery connector from the motherboard and start cleaning right away (+hope for the best)

Ok for the "solution" which might work or not is a disassembly and cleaning of the coffee from the components affected. Usually best way is to use ultrasonic cleaner for the motherboard but since there is noway for that and your laptop is 3+ years old you can try this method below, or take it to professional for cleanup (better changes for recovery unless they just replace the motherboard that cost you price of new laptop)

Thing is after looking at the disassembly it looks pretty hard and time consuming since its opened from the back cover and keyboard is in the front, did the coffee only drip down from keyboard or from side "holes" also?

Yeah, the disassembly is quiet a mess ... i managed to remove all but the keyboard is in ( beleive it or not ) a sealed enclosure ...
From what i could see, no fricking coffee anywhere, i let it around 12h under a 20° fan . And after 24 h i rebooted it, it worked clean no keyboard issue, no fps drop and all.

Anyway thanks for your answer, but the beast is definitively dead, who just lost his pc during quarantine time ?

case closed i can't find where to mark this as " solved" or just to delete it since it don't have any really usefull information

Did you remove the motherboard completely from the case? To check there is any liquid anywhere on the board?

Then it might of just spilled inside keyboard causing the issues but it was packed so tight that didnt leak to motherboard. I would double check it still, problems can arise weeks even months later.
