With Windows 10 it is better to just download the .iso file of Windows and do a clean install. Which you can do from another system. A friend's computer, a relatives laptop, etc.. whatever. The Windows 10 updates are notorious for breaking systems. After you install Windows 10 make sure you got all the latest drivers. That is very important!! Another thing you can do is clean out your system. Get all the dust out of the heatsink, heat sink fan, case fans, etc. As for animation. You may have an outdated or underperforming video card. It would not hurt to do an upgrade. You can get a new one overnighted from NewEgg or Amazon. If you got the money for all that. As to which video card is the best for your needs though that's a separate question. Better to ask someone on here who is an expert in video cards. There is a separate section for those questions. I believe its called "add ons" if I am not mistaken.
On mother's computer. Windows 10 updates corrupted the partition table on the raid array (Raid 0). Had to partition and format and do a clean install. I then booted into windows and set virtual memory which somehow caused the system to not even restart after shutdown. It came up with "No operating system" I then reinstalled windows for a second time but it started up and shut down immediately thereafter. I then put in a new power supply figuring the one installed was shorting out or just bad in some other way. It still did the same. So I figured it was overheating.
I then pulled the fans and cpu and all and cleaned out the system. There was lots of dust in the system so it very well could of been overheating. It still would not start though. Upon inspection I found several broken pins on the cpu socket. Which is not covered under warranty. A pice of food and/or dust from the heat sink and heatsink fan got underneath the cpu some how. Which bent the pins when I removed the cpu for cleaning off and then reapply thermal paste and then reseating.
Nevertheless, I am now happening to do a complete rebuild. Got a new case, motherboard, etc. NOT exactly the same problem you got. This all started with the stupid Windows 10 updates though which is the point I am making. Before doing any updates the system was running perfectly. No errors, faults, or anything.
