Probably A, since if the desktop doesn't turn on at all, that's almost always a PSU failure. RAM, GPU, or CPU issues usually show some signs like fans or lights. I'd go with A unless someone disagrees.
Option A had something like this in a mock, PSU is the culprit when nothing turns on.
I think D here. CPU faults can totally stop a PC from powering up-at least that's what some practice tests push. Not 100% sure though, maybe it's a trick question with PSU as a trap.
B , seen similar confusion on practice tests. Check the official guide for hardware troubleshooting topics.
Pretty clear it’s A. If the PSU fails, nothing at all powers on-no fans, no lights. GPU, RAM, or CPU issues usually still let the system show some activity. I’m about 99% sure on this but open if someone has a different angle.
Yeah, if the PC doesn't power up at all, that's usually a bad PSU (A). RAM or CPU problems give you beeps or maybe no POST, but still some signs of life. Pretty sure this is right-correct me if you think otherwise.
Usually this points to A. PSU, seen that in both official guides and practice tests. If nothing powers up at all, PSU is by far the most common culprit. If you want to dive deeper, check troubleshooting sections in the CompTIA A+ book. Let me know if you think otherwise!
A
Hard to say, A but I could see D tripping people up depending on symptoms.
I’d say A, PSU is almost always the main reason a desktop doesn't power up at all. GPU and RAM issues usually show some fans or lights. CPU could be confusing here, but I think that's the trap.
Be respectful. No spam.
