New PC resetting during Windows setup but stable in BIOS

928 Views 14 Replies 4 Participants Last post by  Blu_86
I've recently built a new pc for my friend and all was going well, I finished and turned it on for the first time and entered the BIOS with ease. I connect my USB with a clean Windows on it and as I start to set it up, the PC just shuts off and resets, it's been doing this for 3 days now and I've never experienced this before. So I cannot setup windows on this PC and am limited to the BIOS. I've pulled the whole PC apart and reassembled but same result. Need help

How far into the install does it get before it shuts off ? Does it actually turn completely off or does it restart ?

Please list the parts you used for the build.
What are your temps and voltages in the bios; specifically cpu temp, 12V, 5V, and 3.3V values?
Until you list ALL of the exact specs, there is little anyone can do to help you. When you list specs, do not post "500W pw supply" Post the exact brand and model# Do that for ALL of your parts.

It gets to the choose drive to download windows on to screen, then it restarts

-Asus ROG Strix B450-f (Latest BIOS)
-Ryzen 5 3600
-Coolermaster Hyper 212 Black Edition
-XFX rx 5700 xt RAW II
-Thermalake Smart 750w
-1TB HDD Western Digital 7200rpm
-Corsair Vengeance 8gb x 2 3200mhz
-Fractal Design Focus G White
The CPU temp idles around 45-47°C and the voltage is about 1.438V
The voltage of the RAM is at 1.350 V and the frequency is 2133Mhz
The +12V is 12.033 V, +5V is 4.986 V, and the +3.3V is 3.335 V

Make sure CSM is "on" since you're not using an SSD yet right? you want legacy support. Also try using a different USB thumb drive. Make sure it's formatted to fat32. Be sure you download a fresh copy of W10 from here
https://www.microsoft.com/en-us/software-download/windows10

Regarding 1.438v on your CPU that's too high it should be around 1.35-1.37v for initial startup Also make sure that 5700xt has all the power connectors secured fimly - try reseating them again.
Those look like decent specs. I have used the corsair vengeance ram in a LOT of ryzen builds and it works great.
Just as a test, boot the system with a linux live usb; use either ubuntu or mint. See if the system will run using linux.

The coolermaster 212 type fans are excellent and I would expect idle temps in the bios to be lower however those are not above limits. While the 212s are very good, they are not the easiest things to install and sometimes the bottom of the fan or cooler contacts the top of the ram chip. This precludes making a good contact with the cpu. If they system will not run linux, be sure and check the cooler.

You don't need CSM if not using an SSD.

A Windows 10 install from a Usb stick made with the Media Creation Tool will set up a brand new drive as GPT with an EFI partition automatically whether it's an SSD or not.

New Status: I undervolted the CPU to 1.36V and it booted fine at first but all of a sudden the system resets as usual but this time it doesnt even reach the BIOS, the LED on the motherboard is stuck on White which means VGA but I've disconnected and reconnected the PCI-E cables multiple times and also switched the GPU locations into different VGA slots and same result. I've been on other threads and they all say a BIOS reset can solve the issue but I can't even rech the BIOS. Then I saw that removing the CMOS battery and using the jumper will reset the BIOS and its settings but I've tried and no result.
How can you not reset the bios??? You simply use the clear pins. Asus calls this RTC or real time clock. Read your manual for specific instructions.
Sorry I have been very busy. Regarding your issues try setting SOC @ 1.1v static (1.1000) and your VDDP @ 1.100. Like the above post says you can clear CMOS with a jumper or by removing the CMOS battery for a few minutes. Try physically reseating the card as well. One thing to mention is that when you set VDDP @ 1.1v and SOC 1.1v you may not need the manual setting of 1.36v on your CPU voltage you can likely use auto and hopefully once booted into windows the auto settings will accurately negotiate proper voltage ramping for your power plan. Now, setting these voltages also means you need to set your memory to XMP in your Asus board called D.O.C.P (you may have already done that). I think your issues are memory related even though you would think it's GPU or CPU related. Your votage should be set at 1.35v when you set D.O.C.P.

Hello I'm back, since the original post we've gotten a new PSU, Corsiar 80+ Gold 750w RM, new gpu, Gigabyte 360mm rx 5700xt, and some new rgb fans, once I installed the new motherboard I was able to enter the BIOS and I thought everything was going fine but BOOM it restarts, so it's either the memory or cpu, oh and I also got a ssd
New motherboard ? What make and model is it ?

Not sure what parts you actually replaced, but from my own building experience the newer X570's need to be put in Gen 3 mode with new GPU's as X570's default to Gen 4 mode. Some B450's do the same with a late BIOS update to support PCIe4 (gen4). It can and does cause Windows issues like yours where it will be ok in the BIOS but not in Windows. Check that please not sure if your board/s? . are running defaulted to Gen4.
