I've been having a ton of problems with Windows 11 on my PC, to the point where certain websites just refuse to work entirely. This has been happening for a while, but it has gotten a lot worse in the last few months. The sites completely fail to load, or certain functions don't work at all, regardless of how many times I refresh the page. I've even reinstalled Windows from scratch multiple times and swapped out my SSD, but the problems persist. My laptop runs the same OS without any issues, so I'm starting to wonder if there's something wrong with my actual PC components. Here's a list of my hardware:
- CPU: Ryzen 5 5600G
- Motherboard: Gigabyte B450 Aorus Pro Wifi-CF
- RAM: 32GB 1,200 MHz DDR4
- SSD: Multiple SSDs tested, latest being 4TB Samsung 870 Evo
- GPU: MSI RX 6600 Armor V1
- PSU: ASRock Challenger CL-650G 650W 80 PLUS GOLD.
Some of the sites that won't work include Depop, Reddit, Poshmark, YouTube, and Facebook. I've experienced these issues on all browsers: Chrome, Edge, Brave, and Mozilla. The fact that these sites work flawlessly on my laptop has me questioning whether my hardware could be the culprit. Any ideas on what could be causing this?

Before jumping to conclusions about hardware, did you use a new USB image with the Media Creation Tool for your Windows installs? It's super important to ensure that every version of Windows you're installing is clean. Also, make sure your system clock is set correctly; time discrepancies can lead to certificate errors when accessing sites.
It sounds like you've already done quite a bit of troubleshooting, but I doubt it's a Windows issue since you're experiencing this on multiple browsers. Have you looked into the possibility of a faulty RAM stick? I’ve had similar issues that were resolved just by replacing bad RAM. It might be worth running a test to see if that's the culprit.
It’s really interesting that your laptop works just fine while your PC has these issues. Make sure your home network setup is solid. If you’re using a wired connection and your laptop uses Wi-Fi, maybe check if there’s a difference in how they connect to your router. Also, try temporarily using your laptop’s connection on your PC to see if that changes anything.
I would take a closer look at your hardware, especially the memory. Have you tried using just one stick of RAM at a time? That helped a friend of mine who was facing strange issues like yours. And don’t forget to check whether XMP is enabled for your RAM in the BIOS—if it’s not, that could slow things down a lot.
Your situation definitely suggests potential hardware issues, especially with the RAM or possibly the CPU. I’d recommend running a stress test like Prime95 for a few hours. Even just one error can indicate something’s wrong. But also make sure to check for the latest BIOS updates too.
