Windows 10: Windows crashing problems

In the last month my computer is crashing every day or every few days consistently. First, I thought it was the temperature, but after adjusting some things I believe it isn't. I have only two dump files because they weren't being saved before. I tried sfc /scannow - it didn't show any errors and to Change SATA AHCI Controller.Here are my dump files: https://www.filemail.com/d/fidetorlwffkbrwDo you know how can I fix this?

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

Windows Explorer crashes and thumbnails problem

Hi, I hope you can help me.
Windows Explorer is no longer showing thumbnails on files played by Windows Media Player. I've run cmd and regsvr32 shmedia.dll and regsvr32 shimgvw.dll. That seemed to solve the problem...but it created a different one. Now when I try to open a folder on an external hard drive it crashes. I read in an old 2008 post it was an avi file causing the problem and suggested the run cmd regsvr32 /u shmedia.dll. That solved the opening problem but recreated the thumbnail problem. Any help to achieve both functions would be greatly appreciated. Thank you.
