Booted PC without one of the power connectors, now it won't boot - troubleshooting

[JosephDuffy]

Hi everyone,

I got a new SSD today and cloned my old C drive on to it so it could be used an my boot disk. This all seemed to go fine, but when I then took out the old SSD and put the new SSD into the old SATA connector, I forgot to plug something in that I had removed to rework one of the wires for some of my fans.

When I pressed the power button I immediately remembered that I'd forgotten to plug it back in, but it was too late, and the machine turned off after about half a second.

I then plugged it back in, tried to boot up, and I get a mangled error message, after seeing the (non-mangled) American Megatrends logo for about 30 seconds (this was normal prior these issue, and quite annoying!)

I've tried removing and re-inserting the CMOS battery, and pushing the reset button on my case (although that just seems to reboot the machine?). The MoBo is a Gigabyte GA-Z77X-D3H.

What are my next (possible) steps to try and fix this, or is this an RMA job?

I've uploaded a few images to Imgur. The red circle is where the connector I forgot to connect is, and the close up is the connector that I forgot to connect. Sorry for the poor lighting; there's not much daylight left so I had to use the flash on my phone. The error seems to read "b a B a B B a a y".

Thanks for any help,
Joseph Duffy

it should still boot with just the 4 pin attached

haha the message I thought it read "bad day aye?" weird

so whats happening now it just loops with garbled bios?

if so power on pc at front powerbutton and soon as you hear fans spin switch it off at the rear psu switch,do that two or three times then power up pc normally

if successful youll see a msg flashup saying main bios corrupt recovering from backup please wait

then it should recover the borked main bios

Should be fine still. Booting it up without the CPU power plug shouldn't damage anything. Would remove the battery again and leave it out for a few minutes before re-inserting it.

While you leave the battery out, have a go at unplugging and re-plugging everything, just to make sure nothing is loose.

I'm not 100% sure what fixed it, but after removing the battery for 5~10 minutes, removing all the components, re-cloning the SSD and resetting the BIOS (once I could get in to it) it's not booted up and working.

Thanks everyone!

Could be that the CMOS was not cleared first time you took out battery, as this sort of issue is fixed with a reset like that 99% of the time.

Glad you got it going again!
