Boot partion files can not be read by CMOS

[steve7233]

The only other USB devices that are plugged in are my mouse keyboard and Wireless headphones, its charger, a steering wheel, and a combination Tripple and double A battery recharger for my mouse AA and keyboard AAA. All of these devices except the AA and AAA charger are from Logitech and the Battery charger is from Energizer.

Remove them all except for mouse and keyboard and see if this changes anything.

Addition: If it doesn't change anything exchange the mouse and keyboard for other (spare?) ones.
If this still doesn't change anything you can at least exclude any USB devices as the culprit.

I don't remember which ones are the mouse and keyboard so I removed them all! I turned the PSUs breaker back on then pressed the power. Not even a beep from the MOBO! Just the same flashing power light. I also checked the surge protected as per the WWW. I also checked my 2 RAM sticks unplugging one then swapping and trying the power each time... Nada. I did read that a USB3 controler needs to be properly shut down or the computer might restart a few minutes later on a Linux system but that doesnt't seem to be this problem.

You don't mention the CMOS battery. Have you tried popping it out? While the computer is off and the power unplugged from the PSU, and wait 30 s or so. Some motherboards come back to life after that.

I have been thinking about that but since it doesn't get to the post then is the battery even relevant yet? Today it won't stay except about two flashes of the power light. I took the front panel off and noticed it was caked with dust. I gout my had vaccine out and cleaned it up then tried the power. It spun around two ties and the power quit. The PSU fan never turns. That worry me. Maybe since the PSU can't get its own fan to turn then maybe it is just giving up. I noticed when I was testing the RAM sticks I bumped the CPUs cooler. It moved a little! Shouldn't the past have made that too stiff to move any?

Vaccine should vaccumm.

On the 2 systems where I have found this necessary, without popping the battery the systems were completely lifeless, various LEDs would not turn on and the PSU fan would not move.

I will test the battery now.

I got the battery out. I can't find my multimeter to test it. I sent an SMS message to a friend asking if he has a CR 2032 battery and am waiting for his reply.

[steve7233]

My friend can't come over right a way. Is it possible to see if the post works even if I can't boot due the grub being installed to the second drive in the boot order. When I get the battery replaced I can go into the bios and swap the boot order. Only possible for this MOBO to read the files of a 2gb or larger SSD from the white port which is first boot hardware wise so changing the order in the bios is the only way.

[steve7233]

Replacing the battery resulted in the running two of the case fans and the power continuing to switch on and off and its still going on and off while I type this. Progress but minimal. Does the battery have to charge or something? No PSU fan.

This really sounds like a defective PSU now - if you already have excluded all attached internal and external devices (also e.g. an optical drive and other devices connected to SATA for example) and the memory modules (and also any cards like a dedicated GPU) as the culprit.
If you haven't: detach them one by one and try again every time to be sure.

I admit a quick and dirty test would be to just exchange the PSU if you have a spare one - otherwise I would suggest to really test everthing one by one and find the exact culprit before you buy any new hardware.

Or if you are unlucky it could be the main logic board itself (if you can exclude all other devices) that makes the PSU behave this way…


PS: -> And don't forget to take appropriate measures to avoid static electricity charge whenever working inside of a computer!

Taking out the CMOS battery is not about whether the battery itself is good. It's a way to reset the motherboard. My understanding is that motherboards have various levels of logic independent of the main CPU; that logic runs all the time the system is off and its job it is at least to watch the power on button and turn things on, including the PSU. That logic gets stuck in on the motherboards that need a reset.

After fidling with ever single connection I now get an error on my monitor about pcie power. Internet suggests not seated correctly in the slot rather than the power cable.

[steve7233]

I think I bought the wrong cable from amazon. I had to remove the PSU because the label is on the bottom of the PSU. It said it is a Rosewill. It is proving to be a huge pita trying to find PCIe 4 X 4 cables that fit this PSU. Amazon search doesn't show them and a Google search can't find the correct ones. RBR1000-M.

May be a real problem. Visiting roeswill.com, on their front page they show Power Supplies under Shop Our Collections, but clicking on the image takes you to the page but simply says "No Products".

Was is the model of the PSU in your PC?
