Mi PC is having some troubles to work properly

Well, it works but sometimes when i turn it on it doesnt load Windows just show a black screen where i can move my mouse
Also when it works is really sloooooooow it's frustrating so i decided to format it to see if it gets better gonna take me 14 hours to format it and i will have to do some backup on a external HDD

If i cant backup i'll have to download again all my games (350 gb) and thats bullshit xDDD

Wish me luck

Sh*t i was wrong its 535Gb of all my needed programs

I know that feeling bro... TOO much space used in games xD.
Hopefully a good format to your pc will fix your issue, but it sounds like some sectors in your HDD might be foulty, I recommend you to run a scandisk after you have your pc running.
The other possible reason might be the RAM, a sector of one of your memory could be damaged. you can run a MEMTEST to confirm this

I had on mind that too...I already format it and stills having some issues i will take your advice i run thoose programs and see how it goes

Hi Jager,

Now that you format and did a clean install of windows 10 ? it is to late but you can still watch this video to see if this was your issue and maybe was the fix.

OK, Here is an update
The first Day i Format it saving some of my files and it stilled having the same problem so what i did was try out the video that Amanxx show me /Thanks for that btw/ I didn't fix my problems either so the last thing that i can imagine is my problems is my HDD i will do some test as Yamaha said ty for that too and see what happens
