Motherboard: MSI B350 gaming Pro-VDH

Processor: AMD RYZEN 5 1500x


The motherboard's bios are updated. and i tested it with another CPU, it works fine.


My moherboard shows CPU error light, i have to manually switch off the system and try many times to make it work. Sometimes it works after two or three attempts. but most of the time i had to gave up trying, because it keep showing CPU error. When it starts, sometimes it hangs (motherboard show CPU error light) within half hour. or sometime it works fine whole day until i shut it down myself.


i built this system, more than a year ago. i had the same problem in the first two weeks or so. but after that it worked fine until a week ago, it start showing CPU error light and won't start or hangs after sometime.


As per operating system, if i use Windows 10, it hangs with different errors and restart. but error i get mostly is, "CPU thread stuck in Device Driver". and i think, i have tried every solution posted on internet. but wasn't able to troubleshoot it. thats why i use windows 7. and  it works fine.
