I've been coming across multiple threads with similar problems and made the assumption it has something to do with asus bios.
I believ my specs are a
RM750 from Corsair
Intel core i7 processor
Sabertooth Z77 Motherboard
Geforce 570 GTX 1280 mb
Not sure about my cpu
Cooler Master HAF 922 as my case
8 gigabytes of ram
I believe those are my specs. I replaced the power supply from a TX750 for a warrantied RM750 about a month ago. Same problems are still occuring, where the computer will not shutdown properly, only the monitor does. Then come the power surges, usually when playing games like Garry's Mod.
