[SOLVED] Computer Resets once during any game, then will be fine until I turn it off

[DoctorNo]

Every time I turn on my computer from being off, I am subject to my computer freezing for a moment, then resetting itself. I can have it mid the first game of League I play, but after that it will be fine to go as long as I have the computer on. I don't imagine this is a temperature issue given that it doesn't occur more than once ever. I also am running into the issue with Apex Legends. I have tried to get through the tutorial multiple times and at different intervals of trying to load either the next objective or when I pick up an item, the game freezes but without resetting itself unless I do it. Two of these crashes have for some reason caused my fans to start spinning very fast, but by no means does it do this consistently. I haven't a clue what it could be at this point so all help is greatly appreciated. I tried fresh installing and that doesn't seem to have helped.

Try checking the rams. This symptoms are mostly caused by faulty ram. Try cleaning the ram if it is dirty and be carefull while doing that. And do try a Ram check.

I did a memory diagnostic and nothing came up. I then tried as you said by going through and cleaning my RAM and that seems to have done the trick. I think one of my sticks may not have been inserted correctly but I have since fixed the issue. Thank you for the advice!
