Windows 10: How to fix black and white mp4 files?

Problem:
Whenever I play an mp4 file from my computer, the appearance of the video is black and white. However, not all mp4 files from my computer do that. It seems like the video files I have created specially from Windows Movie Maker are black and white because videos that I have taken from a video recorder don't seem to be black and white. I also have video files that have been converted from VCR tapes to mp4 files and those are in black and white. Even when I'm on Youtube the video is black and white. I clicked on a video, here;'s the link to it if you want to see what kind of video it is (ღ Kawaii Radio | Happy Music to Study/Relax「24/7」| Kawaii Music LiveStream ☆**Redface( ≧o≦ )o:*☆ - YouTube) and the image of the video is just Japanese anime girls, but when I play other videos that are recorded with a camera or are anime videos, those videos are not in black and white.

Solutions that I have already tried:
I have updated the drive, it is called AMD Radeon HD 8400. I just did this by going to control panel ---> device manager ----> display adaptors
After updating the drive, I restarted my computer and when I played an mp4 video again, it was still in black and white. I was thinking of disconnecting the drive and then connecting it again, but I have no idea if that is going to affect my files because I have a lot of important pictures and videos on my computer.

Additional Notes:

• Sometimes, when I play an mp4 file or that video on Youtube, it would be colorful for a split second and then it would be back to monochrome
• There has been a recent update with my Windows 10, but the files were still fine after the update
• Steam has been recently downloaded on my computer
• When I play my mp4 video on another computer (I used my USB to check it out), the pictures moving in the slideshow is actually colorful, but the mp4 files are still in black and white
• The windows movie maker is actually not original. I re-downloaded it after the update has deleted movie maker. Since I have heard that movie maker is no longer available since last January, I redownloaded it from another site. Still, my mp4 files are still in black and white
• Only videos that were saved as an mp4 from movie maker, videos that have been converted from VCR tapes and that one video on Youtube were in black and white.

MP4 Repair

I gave that program a try last night and it said my corrupted file wasn't the right format..... Although all gopro files are mp4 and the videos before and after were just fine haha. Thanks for the suggestion though. I'll try it again using a bunch of different reference videos and see if that fixes it.

 

Mp4 videos and GIFs are displayed only in the colours black,white and green

It is very strange.At first the mp4 data I opened and played was black and White.Then after skipping a part of the mp4 Play time it was colourfull again.After zooming out of the Video it was black and White again and then when zooming in,in colour for a
few seconds again after then turning black and White.

Edit:I am not sure if it has any relevance but the black and White Videos happened a few days after I bought a Notebook cooler for my Notebook I am using.The cooler works with a usb plug and is put underneath the notebook

 

USB doesn't display MP4 file!


I have a 300kb mix of .png, .jpg, .pdf files on a 4Gb USB drive. I added a 2Gb MP4 movie but it doesn't display in the drive files. I used CCleaner to check the drive F files .. it only shows up as 2Gb of OTHER FILES, but not in the listed files.

Any (constructive) suggestions welcome. I can't remove it as it doesn't show in the file list.
