[HELP!] CPU / Motherboard problem

post #1 of 6
Thread Starter 

Background: I've had this for about a year now, and had it on the same overclock settings. Then just about a day ago, it died and wouldn't turn back on.

Equipment:
CPU: Core i5 750 OC'ed to 3.4Ghz
Mobo: MSI P55M-G45
RAM: 2x4 8GB G.Skill Ripjaws 1600Mhz
VGA: XFX HD 5770 1GB
HDD: 1 TB HDD 7200 RPM 32MB Cache
PSU: Antech Earthwatts 650W
Heatsink: Cooler Master Hyper 212+

What I've already done:
-Tested the PSU in another computer (and the shorting test)
-Tested various different sticks of RAM
-Tested the video card in another system
-Reseated the CPU and Heatsink
-Reset CMOS battery

What I haven't done:
-Tested the CPU or Motherboard in another system (I don't have another 1156 Mobo or CPU)

YouTube Video:


So, I'm pretty sure it's something to do with the Mobo or CPU.

As you can see in the YouTube video, I've taken out the entire system and tested it outside the case on a cardboard box. The system powers on for a second, turns on all the fans, LED 1 turns on, and then everything immediately powers off. You can hear the visible click of the PSU.


I was wondering if anyone else could help me. Since I've had it going for about a year now, I'm really weirded out that this happened sponteanously. I did do a Prime95 test and noticed the heat getting up to 70 C, but that was after a few hours and I thought that was going to be the max temp. I left for a little bit, and found that the computer had shut off. Having OC'ed some before, I thought this was normal, so I tried to turn it back on, being greeted with the same results as described in the above (and in the video). I've stress tested it before, with these same settings and it was at about 65 C. I just figured the fans had gotten a little dusty since then, and it was going to hit 70 C. Even still, I've had this CPU up to 75ish before when I was first tuning my OC, so I figured it could handle it. Or that it would just power off if it got too hot.

Anyways, does anyone have any insights since I can't test it in another Mobo / CPU? Is it the CPU? Mobo?

Yes, I've tried the PSU in another system and another PSU in this system :-/

After reading the MSI User Guide, it shows that the 1 LED means it's in 1 Phase Power Mode. This was always in full (4 LED) power mode when I used it before.

I'm not sure if this means that the CPU is fried and it's turning off before it even gets past 1 Phase, or if it's jthe mobo that's busted.
