I'm not entirely sure I understand how to do this. The HDD is SATA, so not sure how to test that with the probes, the PSU wont turn on if the motherboard 24-pin connecters are not plugged in, and the tutorial doesn't specify how to check the GPU 6pin PCI connectors. I did test a few of the random 4 pin molex connecters that are not plugged in to anything, and they all read as 5.07

Please only test the PSU, the PSU is the most important to test

I guess I just don't understand what you mean. I tried following the tutorial you posted, but as I said, my HDD is SATA so it doesn't have the 4-pin connection like it shows in the tutorial. So I tested a couple of the 4-pin molex that are not plugged into anything and they read 5.07v. The PSU won't turn on if I unplug the 24-pin connection from the motherboard to test it, so I can't get a reading....

I downloaded SpeedFan and took some screenshots, though I don't know if they are helpful at all.


I also found a file under System Information that is flagged as causing hardware problems; bdfwfpf ROOT/LEGACY-BDFWFPF/0000. I have no idea what that is.

The only thing where I'm familiair with bdfwfpf is that it is a driver from Bitdefender, Driver Reference Table - bdfwfpf.sys

My apologies for the trouble, I'm not really experienced with testing a PSU so I'm not a guy that can proper help with it.
I'll request help for this

Small suggestions.

This little program will let you see your power supply voltages.

Download HWMonitor - MajorGeeks

You could also get the reading from your bios and take a picture or just type them in a post.

3.3 volts =

5 volts =

12 volts =

From what I see in post #44 your +12 volts is 6.76 volts.
It shouldn't even boot with 6.76 volts.

Hello Layback Bear, thank you for the suggestion. These are the voltages I got from my BIOS

CPU= 1.156v

3.3 volts = 3.60v

5 volts = 5.040v

12 volts = 12.384v

Those voltages look okay to me. Remember that is while the system in not under load.
Could you put in your system the exact power supply you use.

Example: This is my power supply.
