When I was a kid/teenager, I:
- Burned a motherboard and all the RAM by placing a DIMM the wrong way (don't ask me how, it just happened).
- Broke (chiped) an Athlon XP trying to fit a cooler that was supposedly compatible with that socket. So many popular coolers were so poorly made, and the lack of a metal shim in the CPU made them even worse.
- Burned a Duron and its motherboard when I tried the pencil hack to unlock it.
- Burned a soundcard and some PCI slots from the motherboard ceased to function when the custom watercooling system got a leak.
- Pretty sure I got lots of problems with certain graphics cards not working with certain motherboards and CPUs. Drivers simply wouldn't cope with each other.
- I fried a motherboard's PS/2 port by plugging in an IBM PS/2's keyboard while the PC was running. Can't happen nowadays.. but maybe still can if you really come across a keyboard from the 1980s and want to use it. It's less critical as a USB keyboard will be supported out of the box even to get in the BIOS or UEFI setup.
- I also fried a motherboard just by getting a hard drive on the bottom of the HDD cage while wearing static eletricity inducing clothing.
- Earlier, I melted two of a Pentium 166's pin because the pins had bent and I forced the thing into the CPU socket.. CPU survived and went onto an identical motherboard thanksfully.
- Burned too many Sound Blaster Live to count when running then not fastened to the case and looking at them the wrong way
- Extreme forced must be applied on a Duron's heatsink to make it come off, so I hit a motherboard hard with a screwdriver rendering it useless
So nowadays it's easier. Still, I've recently come across the "joys" of UEFI on a brand new motherboard, everything new except the case and PSU from 2005. Booting USB is harder as you have a choice between "USB : [drive name]" and "UEFI : [drive name]", one of which doesn't work. But then, after creating a nifty scheme (eight primary partitions! woohoo) and installing linux, trying to install Windows 7 just failed and then made the system unbootable. I reinstalled linux and it was still unbootable. Then by chance I saw that booting the HDD entry worked fine whereas the "linuxmint" entry offered by UEFI was corrupt/wrong, and I couldn't remove it (for now).
Then I had to google how to install Windows 7 (which complains the blank partition I left for it was not ntfs formatted.. and after formatting it, that the partition table is gpt!) on a UEFI + GPT computer, it says I have to boot the CD/DVD in UEFI mode, which is not an option I was offered. So I'll have to make a Windows 7 USB stick from a Windows machine (two attempts made from linux with two methods gave me an unbootable one)
So, UEFI has just made stuff harder and cryptic. (it has scary stuff like network access from the setup program or whatever the graphical pseudo-BIOS screen is called)
it's easy for me, when I started youtube didn't exist, I didn't know any Internet forums, reddit or whatever, it was a little difficult, but right now the hardware is much easier to handle and you have a ton of information very accessible
.. leading to a situation where you have to google for stuff to work around UEFI deficiencies ; motherboard manual included is sadly a multilingual "quick installation guide" which gives everything about how to plug the hardware, but no word on UEFI/firmware. It's not clear what can be done from the "UEFI command line" either and given the ease of failing to boot it would be useful to have it detailed in a printed manual
