So today I decided to reinstall everything on my SSD (main drive) but leave my HDD (data) disconnected while reformatting. I had this weird Windows bug that happened, when I try to change my lock screen background, it would just stuck loading but not actually load the new wallpaper & when I try to access stuffs using right click on programs/apps in the taskbar, for example, accessing a certain folder in File Explorer, go to Incognito tab of Chrome instantly. These were the reasons I reformatted. So I installed things little by little. I would check everything after each installation while keeping the HDD disconnected. Then it would be okay. Till I connected the HDD (this was still okay). But when I started verifying game files for my steam games. It was back. What seems to be the problem. For your info, I tried to reformat and clean every drive I had a few months back but it only lasted like a month (because I suspended my Windows Updates) then after the updates were done, it was back. Should I just ignore these annoying things or try to find the cause? Today was like my 10th time formatting in a half a year. I'm tired. I asked my friends if they have these problem. Nah, just me. My OS is Windows 10 Pro if that helps.
