I'm not sure if there are any tech gurus here who know how to test for hardware failure, but my PC has been down for 3 weeks now and I can't get it to boot. I know that my HD is fine though since I was able to connect it to my laptop using an enclosure to retrieve data.
The power supply I was using was confirmed to have burned out so I replaced it with another corsair black, this time 750W. So I know this isn't the issue. I suspect either the motherboard, CPU, or both need to be replaced now. I've ordered a replacement motherboard which will be here next week since I am leaning more towards the possibility of that being at fault now rather than the CPU.
This is what I have observed so far, if anyone has more testing suggestions please let me know.
- When the ATX12V1 cable is connected to Mobo, it will not power on at all. When I press the power button, the fans just barely move, but stop right away, and no further power is transmitted. I have to unplug and replug it to achieve the same effect.
- The new PSU will only power on the computer when the ATX12V1 cable (6 pin CPU power) is disconnected from the motherboard. This is supposed to be plugged in at all times. When not plugged in, the PC powers up.
- When the cable is disconnected and its powered on, there are no lights on the keyboard, nothing shows on the monitor, and the power button does NOT turn the PC back off even when holding it down for a long time. The fans spin but there is no response and it must be manually shut off from the PSU power switch or unplugged.
- Disconnecting the GPU, RAM, and HD have no effect, and there is no beeping noise from the motherboard
- The CMOS button lights up red on the motherboard, but the internal temperature number panel does not. Also, resetting the CMOS/BIOS has no effect. I don't think the GPU is bad and the RAM is easily replaceable if needed.
So any help, advice, or tips would be appreciated. I can't afford to take it to another repair shop right now, the one I just took it to failed to fix anything and I'm better off just swapping out potentially damaged parts for new ones until its working again.
