This new PC runs extremely slowly and doesn’t function properly.
Hey there, I’m facing a tricky issue with my new build. Here’s what’s been happening:
System specs: GIGABYTE B850 AORUS ELITE WiFi7, AMD Ryzen 7 7800X3D, Arctic Liquid Freezer III Pro 360 A-RGB, quiet operation.
Processor: Pure Power 13 M 850W Corsair DDR5-6000 (2x16 GB, 5600 MHz, no EXPO).
Storage: Samsung 990 PRO 2TB NVMe SSD, Lexar NQ790 2TB NVMe SSD.
GPU: ZOTAC GeForce RTX 5070 Ti, solid OC, fractal design, North XL case + PWM fan.
Timeline:
- Saturday: Assembled everything, everything worked.
- Sunday: Still functioning normally.
- Monday: No issues.
- Tuesday: Became extremely slow. Boot took ages, Windows lagged, CPU clock stuck around 0.5 GHz.
- After updates: BIOS updated, RAM re-seated, GPU and SSDs checked – no improvement.
- BIOS defaulted, RAM set to 5600 MHz manually.
- Reinstalled Windows: System worked perfectly afterward. Benchmarks were solid, games ran smoothly at high FPS.
- Tuesday evening: Shut down after testing.
- Wednesday morning: Boot process was very slow again, BIOS took a long time. Restarted once – still slow boot, but eventually got into Windows.
- Tuesday evening: CPU wasn’t stuck at 0.5 GHz, but around 2 GHz; performance was unusable.
- Temperatures: HWInfo shows normal readings, no overheating.
Possible causes could be:
- BIOS/AGESA issue with the new B850 chipset.
- SSD firmware or compatibility problems (Samsung 990 PRO / Lexar).
- Motherboard or power supply unit problem.
Have anyone else seen similar problems with Ryzen 7000 builds? I’m looking for quick fixes so I can order new parts fast. If something’s broken, I’d appreciate your advice before I go to the RMA desk. Thanks!
It seems the issue only appears after a cold boot and a temporary Windows reinstall resolves it, suggesting a firmware problem. I’d look for the latest agesa update for your b850 board, as some beta BIOS fixes these cold boot concerns on Ryzen 7000. Updating the Samsung 990 Pro SSD firmware might have helped earlier, so consider checking that too. Try booting with just one drive installed to compare Lexar and Samsung options. If it works after a warm restart but not after a cold boot, the likely culprits are board firmware or storage initialization. Also, test RAM at the 4800 MT/s speed to eliminate memory-related training issues at 5600.
