In Desperate Need of Assistance In regards To Dying Motherboards.

[seanbrenner]

So let me start off by saying that I built this PC about 3 years ago and all was fine up to around 3-4 months ago. 3-4 months ago my first motherboard died. I got my PC diagnosed to find out if any other components were dead/damaged. I was told my components were fine and that my motherboard had died due to CMOS failure. The replacement motherboard lasted for about 3 months and died due to the same cause. The most recent motherboard has lasted 2 weeks (also appears to be CMOS failure) Each motherboard has died shortly after my PC attempts to boot the PC begins the boot-up process and shuts off immediately. The most recent death is unique in the way that after shutting down it tried to boot again but failed. I have no Idea what is causing this issue and why the issue has become more frequent. If anyone can help it would be very much appreciated this issue is incredibly frustrating and is becoming somewhat costly.

TLDR: 3 broken motherboards with no idea of the cause.

PC specs

Windows 7

8GB 1333 MHz DDR3 RAM

Nvidia GTX 770 2GB

Intel core I5 3550

1TB 7200 RPM HDD

110GB SSD

Corsair CX600M PSU

Have you been updating the BIOS?

How old is the boot drive?

you're missing to much info for us to help you.  What were the make and models of the 3 motherboards that you went through?  Were they all purchased new or 2nd hand?  What exactly happens when the motherboard is dead?  power light but no post?

I have not updated the BIOS and the boot drive is a 3 year old SSD which has had no issues so far.

So the First motherboard was an MSI B75MA-P45 the 2nd motherboard was an Asrock H61M-DGS R2.0 and the 3rd was an Asrock H61M-DGS. The MSI board never made a post beep when successfully booting and the other 2 Asrock boards didn't have speakers if I remember correctly. When the boards died the PC shut off immediately and when I tried to Re-boot all the lights and fans would be on but there would be no signal sent to the monitor. This has been the same with all the boards except the 3rd one which tried to Re-boot right after it shut down.

UPDATE: Issue seems to be a loose connection with 24pin and motherboard due to poor clip manufacturing.

Thanks to anyone who took the time to leave a comment or read my post.

I would try to:

 

1.  reseat the memory.

2. remove video card and use onboard graphics
