Tried to update, computer no longer works.

[Startstooyoung]

Hi, so today I woke up and went to download the new Back 4 Blood game, after finishing that I then decided I'd update to windows 11 and at the same time update my "HP Drivers" I put that in quotes because I'm pretty sure that's what it was but not 100%, was definitely an update involving HP. My computer then told me a restart would be required to start the HP update, so I did, ever since doing that, my computer turns on, fans spin, lights up everywhere, but doesn't read anything going into USB ports, doesn't read any DC or HDMI connectors, and just sits there like that until it's turned off, I've taken all the ram out and tried, half the ram out and tried, I've tried to disconnect certain things from the power supply, tried to mess with the graphics card just to find out I practically have to break the thing to get it out, and found out the white latch that keeps the Graphics card in there, was broken. Everything is in the right spot and doesn't look dirty or broken, just some dust from me being in a very dusty house right by the attic. I've been fighting with it for hours as usually I can get them to work whether it's a phone, Xbox, PC, usually just trial and error before I figure it out, I've searched videos up and other Q&A's but it doesn't seem like anyone is having my exact problem, that I can find at least. Anyone got anything?

@Startstooyoung -- try this:

1. power-off your computer
2. start repeatedly tapping the "ESC" key (top-left of your keyboard)
3. power-on the computer
4. does it display a menu, and does the menu include "run HP Hardware Diagnostics"
5. if so, run it, and choose to run the "Short DST" test of the disk-drive. Does it "pass" or "fail" ? If it "fails", do not run the "long DST".  Note: short -> one minute; long -> many minutes; DST -> Disk-Drive Status Test

Does this help?

The USB ports and HDMI/DC ports have no power so I get no picture or power to keyboard to even try that.

Now when I turn it on it powers on then it turns off after about 5 seconds, now I'm thinking it's the power supply, where can I buy the power supplies that are proprietary to HP with the 7 pin connectors? A 400w one specifically?

@Startstooyoung -- where can I buy the power supplies that are proprietary to HP with the 7 pin connectors? 

I recommend that you find a local owner/operator computer store. Take your computer to them, and get them to find a compatible power-supply, to connect it, and to test it. If it works, then support your local business, and buy it. If it does not work, then they may have some other power-supply that will work.

Note that the primary connector cable from the power-supply has some "square" fingers, and some fingers with rounded corners. This arrangement is designed to ONLY allow the connector to fit into the socket on the motherboard in exactly ONE position.  At ths store, they will know this, and will select a power-supply with the compatible arrangement of square/rounded fingers.

You need this certified driver:

GeForce Driver version 496.13 WHQL

@VH2000 -- You need this certified driver

Maybe, but first, @Startstooyoung  needs a computer that will actually load and run Windows. Since the computer currently does not start, any device-driver cannot be added -- "you cannot get there from here".

@Startstooyoung  could try to remove the disk-drive, and connect it into a "spare" computer, and try to boot that computer from the disk-drive, to prove that the disk-drive is OK.  But, it seems that the motherboard has failed.
