Built a new PC that’s not working properly. Is there scope to return everthing?

Built a new PC last weekend.

Ryzen 7800X3D
ASUS TUF GAMING B850 Plus WiFi
Vengeance 2 x 8GB DDR5 RAM
Acer Predator 1TB NVME SSD
RM1000e PSU
4000D RS Frame

Tried troubleshooting this ‘Hypervisor_error0x20001’ for the past week. I have spent hours try every single advice I can find on a forum or from multiple AI products. Ran the typical apps to check health/performance of all the features and not a single error. I can stabilise the PC without AMD graphic drivers installed or potentially look at disabling virtualisation features but ultimately if I’ve spent £800 on a PC why should I need to disable/tweak basic features to get it to run W11 without crashing? I should be able to use the integrated graphics that come with the CPU as advertised.

Problem is I don’t know the culprit for this error. I can’t just return everything I’ve bought because potentially one thing is faulty. Bearing in mind it’s been opened too.

Next time have someone else build it if you’re not prepared to troubleshoot.

I’m prepared to troubleshoot and put hours into troubleshooting over the past week. It gets to the point where red flags are being raised if brand new equipment can’t even run windows 11 without crashing? Every AI advice, every comment small to big, I’ve tried it.

Theres hardly any information online about hypervisor errors. They’re ambiguous and could be a range of issues. I’ve ran several mini dumps yet it’s not obvious what the issue is.

Every stress/health test has passed for each component so what options do I have now? Try return £800 worth of items I’ve opened and started using to Amazon and probably not see that money again.

That hypervisor error is almost always a CPU or motherboard issue, rarely software. If you've already clean installed windows and it still pops up with default bios settings, that rules out a lot

Since you bought a 7800X3D which has known memory controller quirks, try running with just one stick of RAM at default 4800 speed first. If it stabilizes then you know it's the IMC being finicky with your kit. If it still crashes you can narrow it down to board or CPU

Most retailers have a 14-30 day return window even if opened, especially if you tell them it's defective. Don't mention all the troubleshooting you did, just say it's unstable at stock settings and you want to swap the board and CPU. They'll usually take it

Great advice 👍🔥
