Yo Motherboard

Why is my new PC running so slow despite decent specs?

Asked by CuriousCoder92
I recently built a gaming PC with these specifications: Ryzen 5 5500 6-core processor, a Gigabyte B550 Eagle Wifi motherboard, a Gigabyte Radeon RX 9060 XT with 8GB of VRAM, 32GB of Corsair Vengeance DDR4 RAM, a Vansuny 1TB SSD, and a Thermalright Aqua Elite 360 V3 water cooler. Everything seemed to work fine at first, but now my PC struggles even with basic tasks like changing a cell color in Excel. I'm only using one monitor and have disabled all unnecessary startup applications except for Discord. Even running simple games like Pokémon TCG Live causes stuttering and crashes. It's confusing because I expected my setup to handle modern games smoothly at around 100 FPS but it can barely handle simple tasks.

Are your drivers all up to date? It's important to make sure you’re not running outdated drivers. Make sure all components are adequately connected as well, especially the GPU power cables.

Did you remember to remove the plastic sticker from the heatplate of your water cooler before installing it? That can cause overheating and throttling issues. You might want to run something like HWinfo64 to monitor your temperatures.

Make sure you have the monitor connected to the graphics card and not the motherboard. Since you’re using a Ryzen 5 5500, it lacks integrated graphics, so if it’s plugged into the motherboard, you won’t get any display. Just double-check that to be safe!

Check if the RAM modules are fully seated. Sometimes that can be an issue too. If you open task manager and look under performance, check if the CPU, GPU, or storage is maxed out consistently. That info can help point you towards what's wrong.

It sounds like your Vansuny SSD might be the culprit. Off-brand SSDs tend to have performance issues, sometimes even worse than traditional HDDs. Check your task manager; if it shows 100% disk usage, that could explain the lag. This could be a good place to start troubleshooting.
