HP Omen 15 laptop crashing and BSOD both during idle and gaming

Looking at those two recent dumps I still think you have a CPU that's flaky at low power states. I suspect the only resolution a shop can/will provide is a new CPU.

Since it's a laptop I doubt the BIOS allows you to disable C-States but there is a registry key that allegedly disables the low power C2 and C3 states that you can try if you feel up to it. I've not tried or tested this, so it comes with no warranty from me. Disabling these processor C-States will however keep the processors at full power and this should(!) mask the problem.

1. At a command prompt, run the following command:
2. reg add HKLM\System\CurrentControlSet\Control\Processor /v Capabilities /t REG_DWORD /d 0x0007e066
3. Restart the computer.

To revert back (ie. to turn C-States back on again)...

1. At a command prompt, run the following command:
2. reg delete HKLM\System\CurrentControlSet\Control\Processor /v Capabilities /f
3. Restart the computer.

I will try doing this however before attempting this I noticed the source linked below states its for an INTEL CPU and mine is an AMD, just wanted to make sure that wasn't an issue before attempting this.

Good catch, it may not be applicable for an AMD processor.

You mentioned earlier that Prime95 caused a BSOD running the large FFT tests? That test also stresses your RAM, so a RAM test would be a good idea now.

Download Memtest86, use the extracted tool to make a bootable USB drive, and then boot that USB drive. Memtest will start running as soon as it boots. If it finds no errors after running the four iterations of the 13 different tests then restart Memtest and do another 4 iterations (for a total of 8).

I ran Memtest86 for 4 passes twice. Both times it passed with no errors found. I forgot to generate it the 2nd time but the 1st time I generated a report log which is attached below.

Ok, though bear in mind that this doesn't prove that your RAM is good, it just makes it very likely that it's good.

I think it's worth running the Prime95 large FFTs test again, since that caused a BSOD last time. Please keep it running until you either get a BSOD, and Prime95 error, or the CPU gets too hot. If it does BSOD please upload the kernel dump - it's the file C:\Windows\Memory.dmp. It will be too big to upload here so upload it to the cloud with a link to it here. Then run the V2 log collector again and upload the zip file as well.
