Hello. Recently I started receiving the message "A problem is preventing the troubleshooter from starting." I have a Lenovo laptop and utilize Google Chrome. In addition, my Windows 7 updates now fail to load, my startup repair won't work, and even my System File Checker will not work. Also, my Picasa photos are gone (although most of them, through 2016, are in Google Photos.) Furthermore, my C Drive disk space rapidly disappears throughout the course of the day. I will have 600 MB or so of space in the morning, but by afternoon I receive a "Low Disk Space" notice. According to my Norton full scan, I have no viruses or problems. I tried CHKDSK, but it showed no problems. I tried to load the Microsoft Malicious Software Removal Tool (MSRT), but it wouldn't load. I tried restarting in just about every mode, including safe mode, debugging, and even last known good configuration. At this point, I can't figure out any other option but to reinstall Windows 7, which I don't really want to do. Thank you for reading this message.
