Hi,
This is my first post on here, but you're my last hope
In short: My PC wouldn't boot with just RAM, CPU and motherboard. I tried different RAM sets in different slots without avail. I bought a new motherboard and it wouldn't boot either. Bought a cheap 5 bucks CPU and it won't boot in either motherboard. Using the PSU of a working PC didn't help either. I think my PSU went bad and might have fried them.
I have a PC with a i7-3770K on a IPMMB-FM (Formosa) motherboard which I haven't used in over a year. A while ago I plugged it back in again and when I tried turning it on it gave me 6 long beeps. I got the motherboard+CPU combo from a friend and it has no manual. I found that on similar HP motherboards, this code means "something is wrong with peripherals". I unplugged everything except the RAM but it made no difference. After some more testing I concluded something was broken and decided to find a second hand LGA 1555 motherboard.
I now also have a Gigabyte GA-Z68X-UD3H-B3 flashed with UEFI version U1L so it supports my i7. This motherboard, however also won't POST and gives me continuous quick beeps, meaning "power error". I then attempted to power the board with the PSU of a different PC, but this gave the same error. I did try some thinks like putting different RAM sticks in different slots, but the result was the same.
To make sure it wasn't my CPU that was broken, I bought a Intel Celeron G1610 for €5 that should at least be supported by the Gigabyte board. This, however also gave me the continuous quick beeps.
I now think my Cooler Master Silent Pro M600 has broken down and has in turn broken both motherboards. However, is there anything else I could try? I don't think plugging the PSU into a working system is a good idea to test this hypothesis

Sort of off-topic: In case they're truly broken, would it be better to just upgrade my entire PC? Could I in good consciousnesses sell my i7 without being able to test if it's actually working?
