PC lags when I open anything then is more or less fine until I open something again

I just built a new PC after selling my old one. Everything appears to be fine but when I first load up Windows 11 it lags a lot, then is fine. So I open up anything and it lags again until I give it a few moments. I have no idea what is wrong. I have installed Nvidia drivers and AMD Chipset drivers and all other mobo drivers like LAN and Wi-Fi and nothing has fixed it. My RAM is capable of 7000MT/s but I left it at base speeds until I had everything set up in case anything caused issues. It’s driving me insane. I should also mention that everything seemed to run fine when I took the GPU out and plugged my HDMI cable into the mobo and ran it on integrated graphics. After I also uninstalled the AMD driver software for the iGPU in case that caused any issues, but that also didn’t resolve it. BIOS is also up to date. Here are my PC specs:

  • Palit RTX 4070 Super
  • Ryzen 7 9800X3D
  • ASRock B650I Lightning Wifi Mini ITX
  • Patriot Viper Venom 32GB 2x16GB at 7000MT/s (Current at base clock of 4800MT/s)
  • 850w Gigabyte P850GM V2 Fully Modular 80 Plus Gold
  • DeepCool LT520 240mm AIO
  • SSUPD Meshlicious Mini ITX Tower Case

That is very likely a hard drive or SSD bottleneck. It’s struggling to get the data and load it into RAM. You can run a tool like CrystalDiskMark to find out how fast the read/write speed is and compare to the marketed speeds of the drive.

The SSD is fine, I have a Samsung 980 Pro 2TB that I forgot to mention. It was running fine in my last PC and my Asus Rog Ally.

It could still be issues with the drivers or connection to the new motherboard. Slowness when opening programs but not after they are running is nearly always storage-related.

Ok, will give it a go.

Grab the Samsung firmware via Samsung Magician. Might be as simple as that.

Will do.

Check eventvwr and see if your HD or SSD have any bad blocks.
