I have a desktop PC built in the last year that started showing signs of instability. It would randomly crash sometimes, but not at the OS level -- it would be a hard crash that would corrupt video and audio outputs and completely freeze the system.
I started suspecting the RAM sticks since they have been finicky in the past, so I booted Memtest86 in order to do a full RAM test. Right after setting up the test, I accidentally bumped the case and the test froze.
I then rebooted and tried the same again multiple times. Every time I bumped the case, the system freezes completely. It seems to be more sensitive in the RAM region, so I still suspect either the sticks or the motherboard.
Is there any other troubleshooting step I can take other than start swapping components? I've got no other components nearby and am planning to contact Corsair (RAM) support soon.
