MemTest86+ doesn't relay on the operating system.
Yes you do need a flash drive or CD, memory tests can only test the complete memory when not in the operating system. When you're in the operating system a part of the memory is reserved for the operating system and not accessible by anything else but the operating system which makes that you can't test that part of the memory while in an operating system.
Also be sure your system becomes up to date (do NOT install Windows 10)
Be sure the drivers of your mouse are up to date.
