I'm helping a friend with their misbehaving computer.
Motherboard: ROG STRIX Z270-I Gaming
16 GB RAM
System drive: Samsung 850 EVO 1TB SSD
Whoever built the system for her used a rather large case for such a small mobo and used a Cooler Master liquid cooler with a 120mm rad and fan. The radiator was very blocked with dust as were all the case filters. All this might have caused some overheating.
The problem is that the system is taking over 5 minutes to boot and when Windows 10 finally loads everything run very slowly.
Here's the current startup timing (m:ss):
0:00 - 0:20 : computer starts, a yellow light lights on motherboard for 10 seconds and then goes off.
For the next 4 minutes nothing happens even though the computer is running
4:34 - 5:12 : a white light lights on motherboard
5:12 : the computer turns itself off and restarts
5:16 : same yellow light lights on motherboard for 3-4 seconds
Monitor powers on
ASUS logo and "Press F1 for setup" options text appears briefly (3-4 seconds)
Windows10 loads and starts, but performance is very poor.
Shutting down the computer closes Windows and turns off the monitor quick quickly, but the computer itself takes 5 minutes before powering down.
I updated the BIOS to v1205, cleaned everything up, removed the discrete GPU and am running the monitor off the builtin HDMI port. I installed a new battery in case it was weak and causing some issue with the BIOS.
Tomorrow I'll try a new power supply. But it's been my experience that a system just won't boot with a bad PSU. I'm starting to suspect the motherboard has a problem.
Does this sound like a broken motherboard or might it be something easier to fix?

Hey everyone, I’ve been having a strange issue with my ROG STRIX Z270-I Gaming recently, and I can’t figure out what’s causing it. The system was running fine before, but now it feels super slow, especially when gaming.
The Problem:
- I recently downloaded Minecraft Jenny Mod, and it works perfectly on my mobile, but on my PC, I’m facing low FPS, random lag spikes, and slow loading times.
- Other games that used to run smoothly now stutter or freeze randomly.
- Even simple tasks like browsing or opening applications feel sluggish.
- Sometimes, my Wi-Fi disconnects, and I have to manually reconnect.
- CPU usage seems higher than usual, even when idle.
Things I Tried:
- Updated my graphics drivers and Windows
- Checked Task Manager – no unusual processes running
- Cleared cache and temp files
- Ran a malware scan just in case
- Restarted my router and switched Wi-Fi bands
Possible Causes?
I’m starting to wonder if it’s a network issue since the game runs fine on my phone. Could Cloudflare DNS settings or something else be affecting performance? Or maybe a power setting issue?
Has anyone else faced a similar problem? Would switching to Ethernet instead of Wi-Fi help? Any tips or suggestions would be really helpful!

Hi nohalg1.
You might want to start a new thread with your problem as it's not the same as mine ...
