Ok when u use computers enough the usual problems get fixed. Such as bad drivers or lack of uodates or hard disk corruptions. Here's my current list of mysterious problems and what I think is going on
Spontaneous reboots of an iMac 2008. This has been bugging me for a while. I will get visual freezes where cursors and junk appears on the screen. Lately I've been getting spontaneous reboots. Causes have varied from new gpu improvements put into later OS X releases. The interesting thing is that the spontaneous reboots happen without any kernel panic messages or anything in the console. Current ideas range from hard disk corruption but I don't see any. Lately the reading has been about bad ram. That makes some sense. I put 32GB of third party ram into the thing and the macinrbis 9 years old as well. So on to using Apple hardware diagnostics and loading memtest86 onto a USB.
PC boots to black screen. All the lights flash but nothing appears on the monitor. Calvintong.com actually fixed this. It seems to have something to do with gtx1080 and starting in overclock mode. But he won't tell me!
PC boots occasionally but when you hit the power. The last time this was a blown motherboard where an m.2 ssd had slid under. This one I'm not sure but looks like a short.
