PC specifications:
CPU: 3rd Gen Core i5
Mobo: P8B75-M-LX
RAM: Single stick, 8GB
GPU: GT740
My office PC occasionally fails to display a signal during startup. It may require five attempts before it functions properly.
I've tried several troubleshooting steps:
- Disconnected the GPU and connected directly to the motherboard
- Updated the BIOS
- Reinstalled GPU drivers (while still trying to connect via GPU)
- Swapped RAM stick into different slots
- Tested with another hard drive for booting
After a successful boot, the system operates normally, though it has been reported to reboot unexpectedly.
I don’t have a backup motherboard or power supply, so I can’t perform further tests.
I’m at a loss about the problem, but given the age of the machine—around 10 to 12 years—it might be wise to replace it rather than risk further issues.
Any advice would be greatly appreciated. Thank you.

PC specifications:
Processor: 3rd Gen Core i5
Motherboard: P8B75-M-LX
Memory: Single stick, 8GB
Graphics Card: GT740
When sharing a troubleshooting thread, it's standard to provide complete system details. List the components as follows:
CPU:
CPU cooler:
Motherboard:
RAM:
Storage: SSD/HDD:
GPU:
Power Supply:
Chassis:
Operating System:
Monitor:
Include the PSU age along with its make and model. BIOS version for your motherboard at this time.
Consider swapping the RAM stick into another slot if needed.
Use an eraser to clean the gold contacts on the RAM, remove any residue, then reinsert it carefully. Also, gently blow out dust from inside the system using a soft brush.
I don’t have a spare motherboard or PSU, so I can’t test or replace them.
It might be helpful to borrow a well-built PSU from someone else and check if your current unit is causing the problem. Troubleshooting involves systematically replacing parts rather than guessing who’s at fault. If everyone bought parts based on guesswork, we’d all end up with components similar to two different systems. That’s why we recommend borrowing or swapping parts to test or migrate them safely.

CPU: 3rd Gen Core i5
You mentioned this before. There are several i5 processors in Intel's Ivy Bridge lineup (the platform you're using), which SKU is your i5?

PSU: Corsair RM550
Is this the PSU you're using? Check the specifications section; the warranty lasts 5 years.
PSU age: approximately 8-10 years. Which number applies—7, 8, 9 or 10? In either case, the unit is past its warranty period. Remember that the power rating of a PSU decreases over time. This drop tends to speed up if you expose it to high temperatures, especially when vents are blocked by dust or debris, and if your wall outlet is unreliable.

This isn't about blaming the PSU, but noting an observation. You might want to borrow another unit to verify this idea. If the problem stems from a borrowed PSU, consider purchasing a cheaper replacement for your system and returning the borrowed one.

By the way, does removing all storage drives help with the issue?

Thank you for your input, it's appreciated. I haven't attempted booting without the HDD connected yet, but I'll try it.

It halts at a specific stage, and the process begins when power is restored. When you activate it, the screen remains dark until the system resumes operation. No additional details are provided about further behavior.

I'm probably thinking about your PSU or motherboard because of how old your system is. Since it's quite old, I suggest you replace it with a fresh setup rather than trying to repair it, as that would be the most effective approach in the long run.

Yes, the display remains black with no signal detected. The hardware functions normally—fans operate, HDD makes noise, and the motherboard's power LED is active. Occasionally, random errors appeared, such as "(A7) Me FW Downgrade - Request MeSpiLock Failed" and "Error sending End Of Post message to ME, System HALT!"—these occurred prior to resetting and replacing the CMOS battery, as well as after a BIOS update. Additionally, during startup, the system requested a BIOS password that I was unaware of, which also happened before the BIOS upgrade.

I’m in agreement with cyberflash about this, honestly it seems like the "craptastic" Asus board is entering its last phase.
In a business office setting, have you thought about requesting a budget of $1100.00 to construct an LGA 1200 system?
