I was using my computer a couple of days ago, and out of nowhere, it instantly turned off. The computer was emitting a burning smell and would not power back on.
After some researching I found that this was a problem with the PSU (as far as I know), and that other components could be damaged in the process.
I bought a new PSU and the machine now powers on. However, now it displays a message that says, "The current BIOS settings does not fully support the boot device". and then goes on the tell me to go into the BIOS and change the CSM to enable the boot device. I've done this, as well as changing the Secure Boot setting to 'Other OS' as I had heard from another thread to do so.
Disabling the CSM and rebooting gives me a message which shows all of my computers components, but does not list my GPU, and tells me that 'The VGA card is not supported by UEFI driver.' I am not sure if any of this information is relevant, I am but a mere programmer is all.
In the SATA settings my hard drive is not being recognised, as it is not listed. I tried plugging in my 10+ year old hard drive, but when booting from this my computer gets BSOD'd shortly after.
Any help regards on how to fix my computer and/or if I need to replace any parts would be sincerely appreciated. I apologise for the long question.
