Hello and welcome all community!
My situation forced me to write a post here... Maybe some have an idea what is happening and give me a clue, but from beginning. I have an ASUS P6T6 WS REVOLUTION mobo + Xeon X5660 CPU + 12Gb DDR3 RAM + GTX 1060 GPU running Windows 10. This setup works flawlessly from beginning , but one day it changed. 3 months ago my friend by mistake "plugged" USB in a back of computer under motherboard (cause I forgot to put shield on a back). I was playing on PC and when it happened computer shuts down immediately and my friend saw a little spark. I unplugged power and waited for few minutes. Then I connected power plug and everything worked ok.
Next day I tried to play some games and after loading Windows threw BSOD "clock_watchdog_timeout". Also I noticed drops in FPS under load - didn't happened before. I perform full reset of BIOS and problem disappears till I turned game again. After some time (like 3 minuted) again - same BSOD. I tried to make some benchmarks in safe mode and there were no sings of problem. I reinstalled Windows and installed fresh drivers. Still - some situation.
I made CPU underclock (a little) turned off all ASUS boosting stuff, and then benchmark on CPU passed. PC was working for around 2 months but then : new BSOD appears. "machine_check_exception"
I checked motherboard, measured with multimeter for short circuit around all USB and it's look ok. Temps, voltage and others look fine. Memtest passed, "GPU only" bench passed. Also I noticed, when I plug USB drive, system randomly hangs but I'm not 100% sure that is caused by USB. I tried to unplug everything from back, turned off USB in BIOS and leaves only PS2 keyboard ( not using it for everyday work ) - same situation when I'm stressing PC.
I will be thankful if someone give me some advice to check something, replace, etc. I was thinking about replacing CPU (it's cheap as dirt) or buying new PCIe USBs but I'm not sure if that going to work - should I try? Is motherboard dead?
