Issue with PC restarting unexpectedly after functioning properly for a short time.
Issue with PC restarting unexpectedly after functioning properly for a short time.
I performed numerous troubleshooting steps but remain uncertain about the issue. Here’s what I did:
1. Verified if the device was overheating; it wasn’t, but I replaced the cooler just in case. It maintained a temperature of 32°C and rose to 56°C during the stress test.
2. Swapped out the PSU, yet both units in my other system functioned properly.
3. Replaced the CPU, yet the problem persisted.
4. Used a different RAM module, but the issue remained unchanged.
5. Disconnected all components from the motherboard to determine if another part was responsible. Only the VGA cable stayed connected after removing the boot drives. Still no resolution.
6. Swapped power cables and multi-plugs, and tested alternative power outlets in my room.
7. Updated the BIOS, removed the CMOS battery, but the problem continued.
8. Inspected the motherboard socket and found a pin with a damaged tip.

PC specifications:
- CPU: Intel Pentium G4560 (LGA 1151)
- RAM: 2x 4GB at 2400 MHz (8 GB total)
- Motherboard: Gigabyte B250m D3V 6th/7th gen
- Storage: M.2 SSD 500 GB (boot drive) + SATA SSD 256 GB + 1 TB HDD
- PSU: 500W PC power (Bangladeshi brand)
I suspect the cause, but I’m still unsure. Could it be because the pin remains in contact with the CPU despite being loose? I plan to replace the motherboard. However, I’m anxious about whether the issue will persist after that change. I don’t have a spare 6th/7th gen motherboard for testing. Living in Bangladesh makes component prices higher, and finding old boards is difficult. I just want to be certain.
PSU: PC power 500W (Bangladeshi brand)
This is your issue—source (borrow, not buy) a well-made 450W unit from a friend or neighbor and then run the system.
If the problem continues with a PSU offering at least 450W for the whole system (not just the listed wattage), it suggests a driver, OS, or memory issue.
RAM: 2x 4GB 2400 mhz (8 GB)
Do you have a link to the RAM you're using?
I am from Bangladesh, and component prices are higher there.
Choose quality parts so they last longer.
Have you looked at the picture of the mobo pin? As I mentioned before, I also checked with another psu (Corsair CX 550) but it didn't help. I will definitely buy a better one. I believe the problem isn't related to the driver, OS, or memory since I've verified the memory sticks in my main rig using memtest86 and Windows memory diagnostics, and I've tried booting into BIOS without success. After some time, it restarted again. So it's not an issue with the operating system or drivers either.
Sometimes bios restarts after a reboot, possibly due to a dead CMOS battery. Have you replaced the CMOS cell with a new one? That could also indicate a grounding problem. Do you notice any slight tingling when touching the metal part of your chassis while standing on a tiled floor? Have you verified the mobo pin picture? Yes, I’ve seen it but ignored it when you mentioned operating with different durations. Was the pin damaged before you noticed it? You think we should directly accuse someone, but we’re following a checklist to eliminate possibilities step by step until we reach a clear answer.
I haven't updated the CMOS. And yes, this computer isn't correctly grounded.
I performed numerous troubleshooting steps but remain uncertain about the situation. Here are the actions I took:
1. Verified if overheating was the issue; it wasn’t, so I replaced the cooler just as a precaution. Temperature rose from 32°C to 56°C during testing.
2. Swapped out the PSU, but confirmed both units in my other system were functioning properly.
3. Replaced the CPU, yet the problem persisted.
4. Used a different RAM module, but the issue remained unchanged.
5. Disconnected all components from the motherboard to isolate potential causes. Only the VGA cable was connected after removing the boot drives; still no improvement.
6. Swapped power cables and multi-plugs, tested various power outlets in the room.
7. Updated BIOS, removed CMOS battery, but results were identical.
8. Installed an open hardware monitor; temperatures displayed 90–102°C across two of six sensors.
