After assembling my new rig, and installing Windows 10 Professional (build 10240), I have been getting continual BSoDs. The error code shown is CLOCK_WATCHDOG_TIMEOUT. Bootup happens without any issues. I was able to install the MoBo drivers from the CD. Internet connection works fine. I also installed MS Office 2016. I got about 3 BSoDs within about an hour of the first bootup. And it's been happening every now and then. There is no fixed pattern to the occurrence, nor can I reproduce it. I looked up about the error and almost all resources point to a hardware issue. To be sure, I also did a clean reinstall of Windows but that has not fixed the issue. And it's a brand new setup, so it's not like I am migrating from an earlier version or even an existing HDD. Each hardware component is new. I have done the following troubleshooting so far: 1. Ran MemTest86 and it was 100% successful without any errors. It ran 4 passes which took about 2.5 hours. So, guess RAM is not to blame. But should I run more tests? 2. Ran Prime95 and the system froze up after 5-10 minutes of starting the test. I ran it twice again and same thing happened - the system froze within 5-10 minutes of starting the test. 3. Ran an analysis of the minidump crash files using WhoCrashed, and it also indicates a hardware failure, probably due to the CPU overheating. At boot time, the CPU is at 50-55 degrees Celsius, which I believe is too high for idle temperatures. Currently, I am trying to install the drivers for the GPU. It's taken me few days to do it because firstly, the download took a long time (net speeds were too slow). Secondly, BSoDs happened during downloads. Thirdly, when I was eventually able to download the driver package and run the setup, it told me it's incompatible with Windows and I had to upgrade it(!) So, at the moment, I am upgrading to the latest version of Windows 10 (build 14393). Once that happens, I will try to install the GPU driver. Hopefully, it should work and the GPU should be eliminated from the list of possible failing hardware within the rig. Rig details are as follows: Ryzen 5 2400G Asus Prime B350M-A Corsair CX550 Corsair 8gb x 1 2666Mhz WD 1TB Blue Zotac 1050 Ti 4GB Antec GX200 1. No overclocks done. 2. Cabinet has two chassis fans but the MoBo has support for only one. So only one fan is running (until I get a fan to molex connector cable) 3. MoBo BIOS is updated. The one on the site and on the cd, are the same version. I need help in further course of action if indeed the CPU overheating is the root cause.
