I reached a dead end.
Yesterday I attempted to build a computer for my mom. Here are the specs:
CPU: Intel i3-4170 (new)
Mobo: ASUS B85M-G (old)
RAM: 1x4GB Kingston 1333MHz (new)
PSU: Sentey BRP 600W (old)
As you can see, the only thing I bought were the CPU and the RAM. The old build she had, was already working with that PSU, and I used to have that Mobo on my main build, so I can guarantee you that two months ago, it was working.
I installed everything, plugged in everything, started the computer, CPU fan went on, and nothing. Just a black screen. Won't even get to POST.
Naturally, I tried to narrow down the problem. I plugged in a case speaker, disconnected the HDD and started the computer. No beep. After that, I removed the RAM. That definitely had to beep.
No beep.
I cleared CMOS.
No beep.
I followed the checklist posted here and the extended one.
No beep.
I did recall though, that when I installed the CPU, one of the pins on the socket was a bit bent, so I took the CPU off and tried to put it back to where it belonged with a needle. It looked fine to me after that, so I started everything again, and still the same results.
The PSU was working until yesterday, so I'm definitely sure it's not that, and it's not the RAM, clearly. Either CPU or mobo.
I'm 80% sure it's the mobo, but I'd like to ask you guys first what do you think. Yes, everything's plugged in correctly. My guess is that when I took off my old motherboard and kept it on its box, something may have gone south and that's why it's not working. Also, it could be the bent pin, but at this point, I don't really know anymore. I don't know what else to try. There's a slight change that's the CPU but other than trying it on my own build, I cannot really know.
Any suggestions?
