PC Stuck in startup loop

Hey,

I recently had problems with my computer and it wouldn't get past the windows starting logo and looped back to the options where I could choose between Startup repair (which didnt work because just loading the screen took about 2 hours) or starting windows normally (which also didnt work because it looped me back). I thought that reinstalling windows would be a smart idea and it worked for 2 days... After those 2 days I was back at where I was before, the infinite loop.

I reinstalled windows 3 times already and everytime it does the same.
It works for 2 days and then suddenly gets me to the loop, I did the Computer > properties > tools > check and right after I did this it gave me an error and stopped working again (this time after just 24 hours of reinstalling windows).

I am not sure what to do since my computer is custom build, is it something with my harddrive and can I simply replace it with buying a new one?

Any help is appreciated, thanks in advance!

Cheers,

The first and second time it stopped working I installed a game called brawlhalla as last which were installed a while before my computer actually started looping, the last time it was directx 9 for a game. (Even though it gave the error right after I checked my harddrive so I thought it had to be my harddrive)

I knew deep inside that it was my harddrive, but wasn't so sure. I did manage to fix it for now by switching the hard drives with one from an older computer we aren't using anymore. Im actually being able to write this from my computer right now so I guess ill just have to wait and see if it stops working again, it might be even a bigger problem.

Thanks for now guys, Ill mark it as solved and if problems occur again ill come back!
