Hopefully this is the correct section for the question. I recently built a gaming PC, and ever since I got it together, I've been experiencing constant problems. When I start up the computer for the first time of the day, it's completely unusable. If I try and run any games, they run at 15fps. Even Firefox is very sluggish. Usually, I need to reboot 5-10 times before I get a "good boot". If I restart, and get the motherboard splash screen and my USB devices light up immediately or within a few seconds, and windows loads quick, it's good, and I can run my games at 60fps, all programs run smooth, everythings great. If the BIOS splash screen takes awhile to pop up and/or Windows loads slowly, I'm forced to restart again and again and again until it loads fast, or else my programs are completely unusable. The problem also occurs if I let the computer go to sleep at any point. As soon as I wake it up, the lag is so bad I struggle to even close out of whatever program I was using. Sometimes when I reboot, the computer takes FOREVER to even get back to the BIOS splash screen. This is what I have observed, comparing how long it takes the splash screen to pop up after I power the computer on or reboot it, and how the computer acts each time:
2-3 seconds, it's perfect. Windows loads quick, games run 60+FPS on highest settings, everything runs great.
5-9 seconds, it's slow. Windows takes 3x as long to load, games run 15fps, even Firefox is laggy. Using the mouse scroll wheel causes the screen to look really choppy, like it's struggling. I also cannot watch YouTube videos, or use Google Maps. The video shows extremely choppy, and in the case of Google maps, everything takes forever to load.
10+ seconds, windows takes maybe 10x as long to load, games run at under 5fps, Firefox can barely load anything, even a word document can take awhile to open.
I have updated all of my drivers. I opened task manager to see what was going on with my CPU and memory, and it showed all was well.. Nothing out of the ordinary. I have tried everything I know, and am desperate for help. Does anyone know anything else I can try? Has anyone had a similar issue? I am open to any and all opinions. I have asked this question on other sites and nobody even seems to bother reading my thread, let alone respond. I'm getting so frustrated because I was so excited to build a PC and get into PC gaming, but now it's become a complete nightmare.
Thank you for reading!
