Hey everyone,

I built my computer 4 years ago and it has worked like a charm for the entire duration.

Intel Core i7 920 CPU
Gigabyte GA-EX58-UD4 Intel X58 ATX Motherboard
G.Skill F3-10666CL9T-6GBNQ 3 x 2GB DDR3 1333 RAM
GeForce GTX 295 Video
Western Digital WD6400AAKS 640GB 7200RPM SATA 3.0Gb/s Hard Drive
Corsair 1000HX Modular PSU
Thermalright Ultra-120 Extreme 1366 RT

Recently I noticed whenever I would restart the PC, the first time I turned it back on nothing would load, but the power would keep running. When I would press the power button to shut it down manually, it would turn off immediately instead of the usual 5 second wait. Then I would turn it back on again and it always loaded normally on the second try.

Now it has happened again and finally it is not loading properly at all. At first it was the same routine as described above, power stayed on with no picture and had to do instant manual shutdown. I opened up the machine and noticed the mobo lights would stay on for about 15 seconds than turn off. I hit the reset bios button and nothing changed. Then I tried swapping out the RAM sticks and using only 1 or 2 at a time, now no matter what combination of them I use the lights on the mobo turn on and stay on as if it were booting normally, but I still see no picture. Now I have to hold down the power button for the usual 5 seconds to turn the machine off. The light on my video card is green while the PC is on which makes me think it's working.

I'm not sure where to go from here or what else to try. I would just buy another motherboard if I were sure that's the problem, but for all I know it could be something else. Thanks for any help you can offer!

Hi, Try firstly replacing the CMOS battery with a new one.

Update: Unplugged the hard drive and took out the heatsync in preparation to remove more parts and now it starts up for about 7 seconds then shuts off on its own O_O

Do I order a new CMOS battery from gigabyte? And where in the mobo does it go? Sorry don't know much about these things.

Edit: I think I see it, little round metal battery right? How do I get it out hmmmm.

*Cries*

Nope that didn't work. It's still only powering on for 7-10 seconds then shutting off.

Edit: Ok that apparently only happens when the heatsink is off. Must be some kind of protection method. Now it is back to hanging with all the lights on and fans spinning, but no picture. Takes 5 seconds of holding down button to power down.

Honestly I wouldn't know how to check it or judge if it's good socket quality. I mean I put a fresh coat of thermal grease in there a few months ago when I reassembled it and it's still moist. Other than that I wouldn't know what to look for or how to tell if it's overheating. Any tips?

Try leaving only one RAM stick, graphics card, DVD drive, keyboard and mouse installed. Test with each RAM stick.

Yup I tried that Alex thanks. It was messing with the RAM that got it to change from mobo lights going off after 15 seconds to them never going off.

Are the CPU and case fans spinning when starting the board?
If yes, then I suggest buying a case speaker/buzzer and connecting it to the motherboard. Then start the board with only CPU and CPU cooler installed. If no beeps, then you would know that it's either a board or a CPU issue.

Yes they all spin. Hmmmm with all these purchases for testing would I not just be better off taking it to a local PC shop? One that I called said they would diagnose the problem for $30.

I guess it's better. 30$ is not too much. At least you would know for sure which one failed.

just look at the surface of the cpu and check if those thermal paste flew to cpu pins ~

Nope the paste stayed in place.

Result of the diagnosis, they said the motherboard is dead but they also said when they tested the PSU on another machine it didn't load about 3 out of 15 times and they were worried it may have been the cause of the dead motherboard, does that sound possible to you? It was my understanding that the corsair would just die on it's own when it eventually failed.

Anyway, can someone recommend me a new Mobo to go with my system? The old one is out of production.

Also a new PSU if you think it's necessary.

And I guess since I'm essentially making a new build here, I would like a new casing as well, I don't like my current one very much as my fan placements are awkward and in the way... can you recommend one that maybe already has the proper amount of fans built in so I won't have to ever worry about cooling other than the heatsink?

Thanks so much you guys!

I have many builds using this case and would recommend it to anybody.

Inexpensive and everything fits. Board holes line up good and not too shabby cabling. Three fans already installed and supports two more optional.
