HP Laptop PC 15-dy2000 (2D115AV)

Tl;Dr: I sent the laptop in for a black screen last week to be repaired under warranty. It arrived yesterday and immediately starting crashing, giving the error code WHEA UNCORRECTABLE ERROR. The event viewer has two error codes listed regarding the CPU before every crash. I tried troubleshooting with three different agents other hours and nothing has fixed the problem. 

 

Last week I sent my laptop in for a screen repair under warranty, the laptop would boot up but the screen was black. It just arrived yesterday, and immediately after going through the setup process (they either reset the pc and/or reinstalled windows) the laptop blue screened with the error "WHEA UNCORRECTABLE ERROR" a few minutes after. That was before I got to install any programs or re-download my backed up data off the cloud, all I did was open Microsoft Edge. Ever since then the laptop would constantly blue screen and reboot every few minutes. I did some reading and saw to look in the event viewer, which is where I saw two noticeable errors listed, sometimes multiple times in a session. First one says " A corrected hardware error has occurred", with the source being WHEA-logger and it being reported by the processor core. The second one says "processor 'x' in group 0 is being limited by system firmware. The processor has been reduced in this reduced performance state for 71 seconds since the last report". For the second one there was a separate error listed for every one of my laptops eight CPU cores, and the error would always say exactly 71 seconds.

 

So I contact support via chat they have me go through a bunch of troubleshooting steps; doing a hard reset holding the power button and one of the function keys, restoring the bios settings the default, booting into safe mode, and more (I forgot some of the other things). Eventually he takes control of my screen via the HP rescue program, and my computer restarts multiple times during this process. He runs the fast test through the HP diagnostic program and everything comes back good. At one point I'm assuming he does something I'm not able to see for about 10 minutes, the program was still connected but the mouse was only moving every now and then and nothing was happening on screen (the computer was not frozen). I tell him that seems to work as the WHEA logger error no longer shows up, though there is a new error, the second "processor is being limited error" listed above, but everything seems fine. So we end the chat and he closes the case. The computer is on for about 45 minutes and I install Google Chrome and Steam, as well as the few games I have on steam as well, and suddenly the computer crashes again, without a blue screen (I should note that before this point every time when it crashed except once or twice it would show the blue screen with the error code). Now the computer is back to crashing every few minutes, except now with no blue screen. However, those two errors I listed above are still showing up in the event viewer shortly after every crash.

 

I try resetting the PC but no luck. I saw some things online about changing the power plan to set the minimum CPU state to 100%. Did that but still no luck so I quickly set it back to 5% again after a few crashes. I finally contact support again and inform the person that the problem was not fixed. This is the beginning of a very long hour and a half chat session where they have me do a bunch of things, including uninstalling the two programs I installed, resetting the pc and selecting the option that cleans the drive entirely, and most of the same stuff the first agent had me do. Nothing worked. The computer also crashed during setup as well twice when I reset the pc.

 

Eventually the chat "unexpectedly disconnects" and I gave to get a new agent. They continue to go through more troubleshooting steps, some of which seem to not have anything to do with the CPU and some of which I already did with the last two people, while the computer is continuously crashing every few minutes still, most of the time without a blue screen but with those same two event viewer errors showing up on the list before every crash, strongly suggesting it is crashing for the same reason (and the few times it would show a blue screen it would show the same WHEA UNCORRECTABLE ERROR code). Eventually they ask me to create a windows installation media and I inform them I do not have a flash drive and am unable to one as I was in a bad car accident recently and didn't have any money, despite how cheap they are. They don't seem willing to progress any further until I do this so ask a friend for some money to get a flash drive and create an installation media. The next day (today) I get the flash drive, create the installation media, and reinstall windows. Unsurprisingly, the same issue is happening where the computer is crashing every few minutes (first two times with a blue screen and all the other times without) and those same two errors are showing up in the event viewer. The computer also crashed during setup once too.

 

I don't know what to do at this point. The computer ran perfectly and NEVER blue screened or crashed before I sent it in for the broken screen repair. There were never any performance issues nor did the CPU ever overheat despite me playing a few games on it (not very demanding games). I should add that the screen also broke randomly too, I turned it on one day and it flashed and then just went black and didn't turn back on. But it still turned on normally and did not crash like it is doing now, I could tell it was on from the various LED lights on the keyboard and on the side of the laptop. Also the chat option in my support dashboard is now gone and the warranty status for my laptop says "unknown" which is even weirder. I'm pretty confident that something happened to my CPU during the screen repair and I'm not sure if HP wants to fix it.
