Posting only sometimes?

My computer has been awesome and I have never had any problems until now.  Here is what happened, I was playing video games and when I was done I turned off my computer(no updates) I ate dinner came back and went to turn it back on and it wouldn't post I just get no signal.  

 

Computer components inside:

Motherboard: MSI Z77A-G45 

CPU: i5 3570k 4.4 GHZ @ 1.19 V on a custom water cooled loop (been overclocked since day one to this settings)

RAM: Kingston T1 4 GB X 4 total of 16 GB

SSD: OCZ revodrive x2 240 GB, Kingston 240 GB V300

HDD: 2 TB Seagate 5900 RPM, 4 TB WD 4 TB 5900 RPM

Sound Card: sound blaster z

Video Card: Evga 660 SC (Had 2 until I sold one a few weeks ago)

PSC: OCZ 700W  80Plus modular PSU

 

Things I've already tried:

Reset the bios

Checked the battery voltage(even tried to boot without the battery)

Unplugged everything except one stick of RAM(tried different sticks)

Tried with both the GPU connected and removed

Tried different plugs on the PSU

Different HDMI ports and plugs

 

Results

Randomly posts(once every ~30 tries and only when it sits for 5ish minutes)

I added a picture of some terrible artifacts(only did this once)

 

 

I treat my computer pretty bad heat wise.  I usually turn off all my fans(Except one intake fan) including the radiator fans(I keep an eye on temps to make sure nothing gets too hot (75C on CPU and 85 on the GPU).  My computer was full of dust bunnys and sits on the carpet so the PSU intake gets little to no air flow.  All of this and with running the oculus rift it pushes my PC to the max to get 90 FPS in low settings and generates a lot of heat in Elite dangerous so I started using all my fans to keep temps down.  Other than the Oculus rift my PC hasn't been pushed this hard for long periods of time.  So I might have pushed this old gal too hard.

I have a feeling the PSU had a weird spike(computer is connected to a really nice surge protector) and killed either the CPU or motherboard or even the GPU if not all.  I noticed the HDMI port I use on my screen no longer works when I tested with my laptop.  But I would like to avoid building a new computer for another year so if you have any ideas they would be great.

*Gasp* contracted the red ring of death!  

 

Red screen is one I haven't seen in a long while but in all seriousness, try reverting everything to stock and see if things properly post, if it's still causing problem try resetting the CMOS.

Sorry I accidentally posted before I finished my post(stupid laptop touchpads) I already tried this.  I don't mind building a new computer if needed but I am just curious if you think from the limited information given that the motherboard died?

hmm, didn't even know there was such a thing as the RSOD. Although for OP, yeah first thing he should do is turn off all overclocks and clear the CMOS.

I believe red usually has to do with graphics but not always, I've never gotten one of those before but have had many blue and blank black screen before.

 

Since you already tried removing the GPU and everything go the a bare bones for a post, just a motherboard CPU one stick of RAM and see if it gets past that. Only other thing I can really think of is the BIOS being corrupted.

Darn  well I guess I will be building a new PC (was hoping to see what AMD was going to put out). I will test my GPU in a co workers computer later this week and if it comes back good(I hope its bad since I'm waiting to get a gtx 1080 anyways) I'll assume its either the motherboard or CPU and at that point it's not worth buying any replacement parts.

I fixed it! The bios some how got corrupt even though no hardware change, bios settings, or updates were made.  So when it did manage to post I updated it and now it works perfect again.  Now I have two computers since I already built a new PC  I guess its time to sell this or use underclock it and use it as a server.
