Has your motherboard failed?
Has your motherboard failed?
Hi y'all, I recently had my PSU die and got sent a refurbished unit from EVGA. PC was working fine with the refurbed PSU. I decided to buy a new monitor and now I can't seem to get a picture on any of my monitors. Tried using on-board GPU no picture at all ports along with on the GPU. All monitors work and have been tested with my laptop for confirmation. Upon starting the PC I get LEDs on my GPU and the CPU fan and case fans spin. Here is my current build I replaced my Acer monitor with Samsung's 49" Odyssey OLED G9 Gaming Monitor G93SC. I don't have another Intel processor to test the board. So I am curious if there is anything I can do to confirm that the motherboard is dead or not. Or maybe the CPU got fried? I should also note that while waiting for my replacement PSU I used an old PSU and got picture on to confirm that the PSU was dead. After that I went to plug in my fan controller and a hard drive and the hard drive began to smoke and I lost picture. However, things were back to working with the new PSU. If anyone can guide me to a fix that would be great. Otherwise I will start interacting the the manufacture of my motherboard. Thanks and best wishes, Lazycat619
I need more details about your situation. Could you explain what happened exactly? Did you notice smoke coming from the hard drive, and if so, how did it look? Also, were you using the original cables or replacing them with different ones from another power supply?
I connected the hard drive and it started smoking right away, so I quickly unplugged it. I used the EVGA cables with the other power supply, which likely caused the issue, even though I wasn’t sure the cables were that different.
Wires from another power source might vary. Some makers in the same range could use identical wires, but changing the power supply isn't advised since connections can differ.
That's definitely not a good idea. Combining various cables can lead to mismatched pin connections between the power supply and the cable and the component, using different pins for voltage/ground, etc., which might send signals to the wrong pins. As @Allyxxx noted, this could damage the drive, particularly if you can't check it in the BIOS.
I realized my mistake. The hard drive wasn’t the boot drive. After replacing the other power supply and HDD, my system kept running. I hadn’t altered anything else during the build. Just by unplugging the old monitor and connecting the new one, all displays stopped working—even the BIOS.
