How to improve a computer?

Question

Computers

Friends, good afternoon! The other day, performance in games (cs-go/pubg) dropped sharply (during shooting, I see the game through frames + fps jumps from 40 to 200 and back). Apparently the computer is no longer pulling. Tell me, please, what can be updated in the computer and for what?
I would really appreciate

Answer 1

Everything was fine and then SHARPLY fell ??
in principle, 6 gigabytes of RAM is not enough in 2019))
maybe something else happened with the cooling ..) thermal paste) or moved the system unit to the battery))
and so, in principle, if you want to raise the performance obviously like this:
- look for a processor on this socket and change which one thread i5 or i7 with index K for overclocking)
- the video card would also be changed to something ala 1070 and better)
but still it could not change SHARPLY just like that))

Answer 2

Either a problem with cooling, or you have installed some unnecessary software such as an antivirus that loads the system. In both cases, an upgrade is not required to address this specific issue.

Answer 3

I would add memory ... A four-slot mother, if it costs 6Gb, then obviously not everyone is busy, 4 + 2 for sure. Put 4 more, and preferably 8 :)
Well, remember, have you recently installed antiviruses, scanners, have you opened suspicious letters that could "make happy" the miner?
