For the last week, my C drive has been filling up to either around a couple hundred MB or completely full which results in my computer crashing out. My C drive is small, 32 GB, but the only thing I keep on it is the OS. I have two other drives where programs are installed and I really only use this computer for music creation. All temp files are on another harddrive so that's not it. I know that's a small drive for OS but it's how this comp was set up when I bought it and I've made it work for over a year now. I usually have about 4-5GB free but lately, it's a few MB to nothing.
The thing is, I haven't installed anything new recently and there seems to be something that's just eating up any empty space because I've even tried deleting a few things only to watch any space gained disappear on the next restart. here's everything I've tried so far:
I've turned off hibernation and system restore and deleted system restore points.
I've ran CC cleaner on everything and disk cleanup a million times.
I've deleted programs and files not in use and cleared up a little over a gig just to watch it dissappear.
I've compressed the disk to save space. This cleared up 4.70GB but after I restarted I was back in the red with barely a gig left on the C drive.
I've used WinDirStat. It tells me my largest folder is winSxS at 5.8GB but it freezes when I try to expand and look in the folder. I've tried cleaning out old updates with admin command prompt but nothing seemed to change. For some reason, the Windows Update Cleanup never shows up as an option when I click on system files in disk cleanup and during the loading screen will sometimes freeze when loading on Windows Update Cleaner. My largest file is pagefile.sys at 8GB
I've ran Malwarebytes a million times and it always comes back with nothing.
I'm out of ideas and unsure of what to do. My plan is to buy a larger drive and clone the C drive soon but I'm worried if this is malware or a system error that it'll just do the same thing on a larger drive. Any help would be greatly appreciated.
