I have a problem that lasts for nearly half a year. PC hard-resets straight to BIOS POST (without BSOD) from time to time. PC isn't overclocked (at least intentionally). It doesn't look like it's connected to any specific activity i.e. may reset while just browsing Internet or playing a game or even in idle state at desktop. PC may work stable for a few days and then hard-reset five times a day.
My current OS is Windows 10. First thing I did was turning off automatic restarts and turning on writing minidumps. Then checked logs: https://pastebin.com/PPavraJZ
It's not clear what the problem is other than that it may be connected with loss of power.
WHEA_UNCORRECTABLE_ERROR (124) A fatal hardware error has occurred.
I'm not sure how to interpret all that but to me it looked like hardware issue.
So thinking that it may be hardware issue I did the following:
- Replaced old PSU.
- Got memory out. Cleaned all slots with can of compressed air. Put it back.
- Replaced thermal compound on CPU (used mx-2). Temperature dropped 5-6 degrees. At max load it now stays at about 70 degrees.
- Updated to latest BIOS.
- Reset all BIOS settings to AUTO or defaults.
- Installed latest AMD chipset drivers. Selected optimized Ryzen power profile.
- Removed all MSI software... just in case it overclocks something.
- Ran memtest for half a day without issues.
- Ran Prime95 for an hour without issues.
My current hardware:
- Seasonic Titanium Prime 750W.
- AMD Ryzen 1700 with stock Wraith Spire RGB cooler.
- MSI B350 TOMAHAWK (MS-7A34). Latest BIOS (1.90 from 09/19/2017)
- 16 GB DDR4 RAM (8+8). 1600.0 MHz (DDR4-3200 / PC4-25600) Corsair CMK16GX4M2B3200C16.
- MSI GeForce GTX 1080 Aero OC 8GB DDR5X.
- OCZ-VERTEX4 as primary SSD. Healthy.
- Samsung SSD 960 PRO 512GB as secondary SSD. Healthy.
- ASUS Xonar D2X.
- USB keyboard and mouse.
- KX-MB1500RU Panasonic Printer connected via USB.
- Case is Thermaltake Tsunami Dream.
I'm out of ideas so asking for your help on how to diagnose and fix hard-resets further. Thank you.
