Cpu problem (maybe)

[heman_lam]

i have a Dell inspiron 7447 Gaming laptop
Spec: core i7
Nvidia gtx 850m
intel graphics
8gb Ddr3 ram.
so normally i get around 150 fps on CS:GO, But one day i cant turn on my laptop it beep 8 times. So i took it to my local computer store (no more warranty) they said that my CPU have some problem and they can fix it for 50$ without and Degrade. and after testing at the store it seems fine, Run up CS:GO about 130-140,so after i took my laptop home it seems to run fine the first day but after that my game runs at 40 fps max. i don't know why, i called them they said they didnt touch anything on my laptop. Guys please help

Just a lesson, when you hear a motherboard beeping repeatedly those are codes it's physically giving you. A 8 beep code for that laptop means LCD failur. Are you sure it wasn't 7? 7 beeps means you're having CPU failure.

no it 8 beep im sure, i know that it lcd but my lcd is just fine. now i can play normally but it just very low,like my laptop is broken or something

- reset bios settings
- check power scheme
- check background process
- check cpu temperature

seems one of above may help
