I've been doing more reading and found out that the MOBO should make *beep* sounds when booting it with memory issues. I'll try taking out the RAM stick to check if the MOBO can detect at least that.

Alright, I'm probably just going to ask the repair shop beforehand how much a diagnosis will cost before bringing in the PC. I appreciate the advice.

Thanks for replying. I don't know anybody who has a gen 2-3 Intel mobo/CPU laying around so that's a no-go for me. As for the repair shop, well, I live in the EU so PC repair shops are a bit scarce to come by. Also, I'm not even sure if it's that worth it. Won't they charge for the "repair"?

As the title implies, I have a PC on me whose PSU failed and is completely unfunctional. It's a mate's PC and it's been lying around for a while. He gave it to me cuz I could potentially do something with the surviving components. I tried simply switching the PSU, but it didn't boot. Then I played around with the memory and I found out that 3 out of the 4 RAM sticks are not functioning. After I took the broken RAM sticks out, it powered up (all the fans started spinning) but it didn't boot properly, it just had a straight black screen. Now I'm trying to find out which components are dead or not. Any tips would be appreciated on how to proceed. Specs: ASUS Z77-V LX2 motherboard Unknown gen 2-3 CPU (haven't checked, don't have thermal paste around yet) 4 sticks of 4GB DDR3 RAM (3 of which are dead) A GTX 750 Ti I had laying around to output to the display Wireless Internet PCI-e card DVD drive I know the specs are kind of obscure, but there's not much I dare to touch for now.
