Hello everyone!
First of all the specs:
AMD Phenom II x4 955 Black Edition
MSI 770-G45
XFX Radeon HD5770
4Gb of RAM (2x2Gb sticks)
PSU Antec EA-430D (430 Watt)
Case Antec NSK4482B
Several days ago my computer suddenly shut down by itself and was showing no signs of life. It has already happened to me once, but back then the PC was under guarantee, so the store where I bought it fixed the problem by replacing the motherboard and the PSU (turned out they were dead). I no longer have the guarantee so I decided to repair it by myself.
Firstly, I thoroughly tested the PSU with a tester (I have this one). According to the tests the power supply was working properly. (Except that the tester showed that it delivered 4,9V instead of 5V and 11,9V instead of 12V, but as there were no error signals whatsoever I assumed that it doesn't matter).
Then, I replaced my MSI motherboard with an Asus M5A78L-M LX V2. The only problem that I encountered while connecting all the stuff is that the Power LED connector is 3-pin and the new motherboard supports only 2-pin. I left it disconnected, this doesn't really matter anyway? I tried booting up with just the CPU, only 1 RAM stick, no video card (as there is a graphics chipset anyway) and the HDD (S-ATA). Nothing. I even tried to turn it on with a motherboard outside the case as some forums suggested but still without success...
Should I try to replace the PSU anyway? or maybe there is another cause of this problem? Any help will be appreciated!
Have a good day
