Hey everyone! I just finished building my first gaming PC yesterday, and I'm running into some serious performance issues that are making it nearly impossible to use. Just to be clear, the HDMI is connected to my GPU and not the motherboard. Here's what I'm experiencing:
- Overall, the performance is really slow; my cursor often gets laggy.
- I'm only getting about 30 FPS in CS2, and CPU temps are around 60°C. Sometimes, the monitor loses connection and goes black while under load, forcing me to restart.
- While temperatures mostly seem normal, HWMonitor indicates they spiked to about 90°C occasionally before settling back down.
- Lastly, there are audio crackles and glitches when I use the monitor for sound (might be a setting issue since Windows isn't activated yet).
The memory and SSD speeds look normal, but I'm pretty new to all this, so I could be missing something.
Here's what I've tried so far:
- Enabled XMP/EXPO for the RAM in the BIOS.
- Set PCIe to 4.0 instead of Auto in the BIOS.
- Updated the BIOS to the latest version (Gigabyte F34).
- Installed the latest drivers for chipset, AMD GPU, Wi-Fi, Bluetooth, and audio.
- Checked all internal connections.
- Made sure no plastic is left on the cooler and that the thermal paste is applied properly.
- Updated Windows power settings to use the RX 7800 XT for graphics.
- Even reinstalled Windows.
What I'm suspecting now is that it could be an issue with the PCIe riser cable. I haven't installed case fans yet, but the temperatures seem mostly alright—am I wrong to think that's not the main issue? Here's my build:
- SSUPD Meshlicious with PCIe Gen4.0 riser
- Ryzen 5 7600X
- Sapphire Radeon RX 7800 XT 16 GB
- Gigabyte B650I AX
- Kingston Fury Beast 2x16 GB RAM
- Kingston Fury Renegade 1 TB SSD
- Noctua NH-L12S Cooler
- Asus 27-inch VG27AQ3A monitor
Any help or advice would be super appreciated!

It sounds like something's not quite right with your setup. First off, benchmark your apps like CS2 and check both CPU and GPU utilization. Look at clock rates and temps too. Something's definitely underperforming, but you can't fix it until you pinpoint the faulty component.
Also, are you required to use that PCIe riser cable? They're known to cause issues sometimes. If you haven't already, run the PC with the side door off to keep things cooler while testing. I know you think missing case fans shouldn't be a huge deal, but if there's a heat issue, it can help stabilize things for testing.
I just tried it without the riser, but my FPS in CS2 dropped to only 10! So, the riser might not be the main problem. Do you think it could be my motherboard that's faulty?
