Multiple Memory_Management and KMode_Exception_Not_Handled errors

[Recyclex]

Most of them happened while playing Warframe, some just randomly appeared. Sometimes the whole PC freezes and no response unless I manually restart it, then it doesn't leave any dump files. Asked around for advises, did a memtest with 3 passes, everyone said it seemed like hardware problems, but no one could pin point which pieces of hardware exactly. Help is very much appreciated.

Edit: added new dump file report, also posted on #4.

Hello Recyclex and Welcome to SevenForums

Did you do a Whole Memory Range Test?
Start MemTest, press C (configuration) and then select Whole Memory Range.

I didn't change the settings for the test, so it would be in whatever the default test range is.

Did a whole memory range memtest yesterday, 6 passes, 0 errors.

Though I did get some more BSoDs just this morning. They're in the attachment.
