Laptop is crazy? Time he goes, sometimes not?

I have a little problem with my laptop. For info: who is about 2 years old, from Asus and has cost about 550 ¬ … Unfortunately, nothing is accurate but I think so synonymous not so relevant to my problem. This is namely that my laptop is rumspackt about a quarter of a year… That is… It may be that he works Monday, Tuesday, Wednesday super and all games (mostly GTA 5, CSGO) Run smoothly and on Thursday, where I do nothing differently than the days before, he hangs up after 5 minutes and hangs 30 seconds or totally crashed… Then do not even play more games like bsw Mineraft… Then there are days where he does not Monday, Tuesday, Wednesday and Thursday suddenly everything is running again and I can gamble for 5 hours without a hitch… The next funny thing is… Sometimes I leave my laptop on for days (so shut it up) and it all goes smoothly, and then suddenly it stops… And then again… Sometimes I'll switch him out and when I go back up there's nothing, sometimes it is only after a few hours well and sometimes he has felt synonymous only 2 days to run until it is… Then there are days but there he goes directly after the start… I do not understand the thing and have no idea where the error lies… I'm grateful for any kind of helpful answer

Charge the battery more often

My laptop is actually always on stream

And that's the mistake, Mien Jong

Okay, but I have to be on the cable to play because my PC is slower otherwise and does not pack… But I will if I do not need him to do the cable thanks

But then you should take out the battery. He will break the permanent charge

Okay i'm not sure if you can turn it out but like i'll try if i do not use the laptop to load it or just load it when i'm playing
