It's my son's. He said his computer wouldn't turn on when we got home this afternoon. Me being a data center guy said well let's check the power cable. Sure enough it was unseated. Reseated it. Pressed power button.

Computer came on, but only black screen with a cursor.

I googled enough already to find a way to BIOS screen, but nothing from there has been useful to me. How can I get windows to load from BIOS? Also, it's not a Windows bios, it's some kind of MSI BIOS that looks fancy. Mouse doesn't work but keyboard does, I can cursor through stuff.

Any advice?

Win11 in case that matters.

Start unplugging stuff from the mother board including ram. The start adding it back and trying to turn it on. I thought maybe those MSI type bios screens had USB mouse support.

I get the black window/cursor flash when there is no bootable drive present. See if all the drives are showing up in the bios and make sure the OS drive is listed first in the boot order.

What does "hotplug" mean? Bios display show two drives, a 500 GB showing as "hotplug disabled" and a TB drive showing also "hotplug disabled".

hotplug means you can add or remove the drive while the computer is on. If hotplug is disabled that means you can only add or remove the drive when the computer is powered off.

Boot Option 1 is set to UEFI Hard Disk. Which sounds correct.

Some BIOS have something like, "fast boot" options. I usually disable that.
There's a setting in windows to disable it as well. They do different things, but some graphics cards have issues with "fast startup."

Anyway, I bring it up because my kid's PC would have issues with cold starts, and after some digging around I discovered that setting. Seems to have resolved it.

Make sure to check the other end of anything attached to the power supply, as well as the other tiny cables that lead to the CPU fan. And the SATA cables, if any. I’m guessing the SSD has a screw attaching it to the mobo, so that should be fine.

They do, my son's mouse is wireless, I plugged in my wired mouse and the mouse works on the MSI bios.

this seems unlikely. the kid will figure it out if you give him google and a couple hours time.

You are wrong. This maid I've been wanting to fire for months, she's a bull in a china shop. My wife doesn't want to fire her yet.

Funny thing about that, without his computer, he can't use google. And I'm not giving him access to mine. Weird concept for you?

I don't know what this means or if you are being sarcastic, what is this and will this help?

Never post here on the tech board, but this is a weird concept to me yes. You want to restrict him which I get, but don’t want him to learn a new skill by trouble shooting this in his own. Add an account to your computer with restrictions and let him go with the boundaries this is to solve the problem and nothing else. You don’t trust your child to follow those directions?

He’s taking that position because a properly installed power supply is generally screwed to the case in all four corners, making it functionally impossible to “knock loose”.

Anyway, list, in the order in which they appear, every drive listed in the boot order you’re seeing in the bios/uefi.

I don't trust adults to follow directions.

Unfortunately, most Linux for regular people proselytizers aren't joking. Telling your kid to try to boot to an unfamiliar operating system to search DuckDuckGo on why the system won't finish POST is a moronic answer. That's not why people post here instead of Reddit \r\I_LUV_Linux_and_Homebrew_Machinez .

If your maid is that bad, she probably did knock something loose. Assuming the power cable to the wall was hanging on by a thread, I can see how that can happen. If it was even moderately secured, she hates your family and everything about your house to hit it that hard with a vacuum.

How old is your son?

Instead of Google ask Grok or ChatGPT, describe what happened and what you are seeing. Give it the make and model of the motherboard and the attached peripherals.

Does the motherboard have a BIOS LED (typically two digits) that displays error codes?

There is no such thing as a Windows BIOS. BIOS's are from the motherboard manufactuer, in your case MSI (A common brand)

Most likely, the son is lying. He got excited playing a game and knocked his pc over or whatever. A simple power cable being loose isn't a power supply being knocked loose. It's a red herring. At least it's just a simple ssd chip drive replacement and windows install and he's back to downloading things he shouldn't be.

I realize you don't know much about computers, but if you watch a few videos, then you can learn how to make a bootable usb thumb drive to repair your windows installation. But before you do that, learn how to install a ssd so you can make sure it's not out of socket. With any luck, it's out of socket and you can pop it in and it boots right up. If not the next luck would be it just lost a boot sector and can be repaired easily. Worst will be total loss and replacement of ssd and windows and whatever was on the drive.

FWIW, Maybe it was the maid, but usually it's the kid lying. I realize it sounds horrible to say that, but they're people too and everyone lies.

He was on it that morning, working fine. Got dropped off at summer camp. Maid came. I picked him up from camp, got home, he goes to turn on computer and it won't turn on, no power. OP is the rest of the story.

This maid has fricked up two shower heads already. And some blinds. And my stovetop ignition.

Is this stuff Geek Squad can do?

Yes, it's (no offense) stuff I learned before I was 13. The advantage is that they will have spare parts to swap in if they need to, whereas you don't. It's probably connections, but it takes someone with a bit of mental disability to check every wire and every connection. Judging by the looks of Geek Squad, they're me 35 years ago, so you should be fine. It may cost you their appointment fee, but it shouldn't be that hard.
