Good job. Makes me smile.
Keep a Win7 base image from right after setup when it's runnning best. You may have to rename it or place it in a folder so it isn't overwritten if you schedule subsequent image backups, which will already be unknowingly gathering creeping corruption.
Nothing will replace a clean reinstall except this image made right after you're setup and running best. I have one
SysPrepped which I use for most all my own installs.
My God, that's beautiful, I wish I had known about that before, but it'll actually come in handy real soon as I hope to buy myself a new computer, a more Windows 7 compliant computer. ;D
Also, just a quick update, my computer started to do this again and I think I know the cause as I fixed it this time, the program Game Booster by IObit has a flaw in the newest Beta (Beta 3) that really messes with the system, as Windows 7 can update while it's operating and GB shuts down some Windows applications to make game playing smoother as that was a huge problem I had was that games would start to glitch then go back to normal due to Win7 wanting to update or just goofing off in the background, but as I shut down Game Booster the other night, my computer was extremely slow, Firefox didn't want to run, it showed it running but it did not come up, Google Chrome ran but web pages would just say "Waiting for Cache" but the pages would load, but very slowly, slow slow, even the startup page which is just Google.
Well, I made a backup right before installing GB, and restoring to that did not work, so I popped up Safe Mode, Explorer.exe crashed about four time, as I brought up MSCONFIG and shut down all services and startup programs besides Microsoft services then restarted and brought Win7 back up in Normal Mode then quickly ran into Programs and Features and Uninstalled Game Booster, then I ran Malwarebytes just to be sure it also wasn't malware or a virus, then I ran a boot time CHKDSK on my Win7 HDD, and when I brought it all back up, it had to update, so I allowed it to then restarted again and now it's running awesome again. But the problem with this "problem" is that a restore point almost never fixes it so if anyone has this problem, I recommend doing a clean boot, start in normal mode then Uninstall every new program in the time line of when it started acting up, then run Malwarebytes and CHKDSK, just to really make sure it's fixed then make a restore point and an restore image if it's running well.
Good luck to anyone else who has this problem and hopefully my fix works for you.
On a side note, it makes sense that it was Game Booster as I had the same problem the last time cause I tried to play the Homefront Demo on my PC, so I used game Booster because my CPU wasn't nearly fast enough for it and I was able to play it but after I started having that huge slow down problem and that's probably why my computer froze when it did but there was also a corrupt Win7 Update but a restore would have fixed atleast that aspect.
