Components illuminate yet there is no data transmission from either side of the interface.
My partner's laptop experienced some strange behavior recently. It would operate normally at first, then randomly shut down without warning before restarting as though it had just been powered on. Occasionally, it wouldn't fully power back up, but the internal parts like RAM and fans would remain active, spinning continuously. We had to force a reboot for it to turn on again. After investigating, we suspected the power supply unit (PSU) was the issue, so we replaced it and it worked temporarily. Later, it would restart sporadically. Recently, it shut down but stayed illuminated, so we forced it off and tried again—this time nothing happened. Now the machine lights up as if it were on, but no output appears from the screen or keyboard. The monitor stays on, yet everything seems dead. I’ve checked CMOS settings, reset the power supply, and even swapped out the RAM and GPU, but nothing changed. My only guess is a failing motherboard, though it’s only been a few months. I’m hoping someone can help, especially since the new PSU didn’t resolve the problem. If you have any advice, I’d really appreciate it.
It seems the system hasn't received any significant Windows or BIOS updates recently, which might affect performance even though the hardware itself is brand new.
Front I/O confirmed? Make sure the cable is connected to the GPU—HDMI or DP?
Sure, we’ll also connect the HDMI and DP to the GPU. Keep in mind this machine isn’t brand new—it’s been running for a few months and has been acting strangely.
the issue lies in gradually swapping components until you identify the cause, begin with the RAM—verify it matches the motherboard specifications. Next check the motherboard, then the PSU, followed by the hard drive, GPU, and finally the CPU. I’ll skip detailed reasoning here; just know this is the logical path. *I’d prioritize replacing the PSU first because its reputation for causing problems is well-known.*
