The Gigabyte PC powers up and shuts down.
Hello everyone, I recently purchased an old PC paired with a GTX 750 Ti. Everything functioned properly until I discovered the BIOS was running outdated firmware. I chose to upgrade to the latest version, and the process went smoothly without any problems. Afterward, I attempted a fresh Windows installation by shutting down the machine and restarting it. It briefly powered on, fans started spinning, but then shut down completely with no further action.
I connected a speaker and, after removing the RAM, it emitted a beep. This suggests the RAM might not be the problem. I tested all available RAM slots, disconnected everything except one RAM stick, the CPU, GPU, and power supply unit, yet nothing worked. I also tried re-seating the CPU, but the issue persisted.
This setup is my first attempt at a high-performance system (it’s quite old), so it feels a bit disappointing. Additionally, the LED indicators on the CPU changed color—green, green, green, then yellow, red. The components listed are: Intel i5-2500, an unknown stock CPU cooler, a Gigabyte GA-Z68XP-UD4 motherboard, 4x4 DDR3 Corsair 1600MHz RAM, a Samsung 870 EVO SSD/HDD, and an Nvidia GeForce GTX 750-TI GPU. The power supply is an XFX PRO450W, and the case appears to be a type of “Sharkoon.” The operating system is Windows 10 22H2 64-bit, with a Dell 19” E2216HV monitor.
I found a video showing the startup process here: https://streamable.com/98opc7
I can't believe this… all four RAM modules were faulty? I tried a Samsung 4GB RAM and it worked after posting, now it's functioning properly—what are the odds! Everything seems to be in order now.
PSU: XFX PRO450W
Current age of the PSU is uncertain, possibly around a decade.
When sharing troubleshooting threads, it's standard to provide full system specifications. Please list details such as:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
Include the PSU age along with its make and model.
Just a note, you should connect your display to the motherboard's output since it has an integrated GPU. You only need to link the display to the system.
The PSU model is XPS-450W-SEW and I’m not sure of its age, but it must be quite old. Here’s the serial number if you need it: M81037795.
I plan to test it with the iGPU later today as you suggested, thanks.
I also updated the system specifications there.
