So I have been having an issue with my motherboard. It's a ASUS Sabertooth P67. Had it for roughly 4-5 years. I recently got upgrade to GTX 970 and I got a good hour of gaming out of it. Than I rebooted to install new cables. But upon rebooting, my computer acted like a 1994 astro van in a MInnesota winter. It wanted to fire up than just shut down. Than will not boot up. The only thing that fires up is the mobo LED standby light.

This issue started before dropping in a new GPU. about a month before it started to hicup. I had to unplug the power and hold the power button for 30 seconds. 96 percent of the time it fired up. All seemed to run back to normal. At first I thought it was my PSU since it is about 6 years old so I ordered a new 970 and PSU.

I've tried swapping out my PSU (old Corsair 1000 WATT with a EVGA 850) Same issue.
Used my old GPU (GTX 560). Same issue.

I did have it OCed. This is what I had it at. After it started to act up, I tuned it out a little.

It ran perfect for many months. I have great air flow and clean the inside every few weeks. I did two years in computer repair and did ALL the little tricks and even asked my colleges. All just couldn't figure it out.

I don't want to settle on the mobo being dead. I spent my last college refund on the GPU and PSU. Plus, I'm the type that has to know exactly what happened.

So anyways, there is my issue. After stay up all night and searching Google and reading my college books, I just cannot give up on this! Plus, I had this WHOLE weekend set to play games set to ultra and all that. Since I got "The Division" for free, I'm really excited to play it on March 8th!

Now for my possible solution: I stumbled upon a blog about this guy saved his motherboard by flashing his BIOS chip. I asked my college geeks and they never heard of it. I ordered: USB Programmer CH341A Series Burner Chip USB Programmer CH341A Series Burner Chip

Which it will be here tomorrow. I figured, I'd spend 10 bucks on one last attempt before I have to shell out food money for a new motherboard/CPU/Ram.

Has anyone tried this? If so, what are your experiencs? and possibly give me a few pointers?

Thank you for your time!

I'm a little confused as to what the actual current problem is as you're kind of all over the place. Why are you running without power in the video? Of course that's not going to boot in anyway possible.

Regardless, flashing the BIOS isn't probably going to do anything.

I know it's all over the place. Blame it on my A.D.D. Anyways, The issue is I swapped out my old GPU GTC 560ti for the GTX 970) than fired it up and played hardcore for about an hour or two. I than rebooted (to install updates in Windows) When I fired it back up, it spun over twice, (fans kicked on) than quit. Tried again, nothing.

I posted that video because I was monkeying with it on my desk with my old GPU installed and all of a sudden I noticed the fan twitching. Thought that was weird.

So someone mentioned it could a currupted BIOS due to the fact I had that thing OCed. And adding a new card could have tweaked something. I don't know. I'm trying everything before I drop 500 for new parts.

No, if it was OC'd and that failed, it would more than likely revert it's BIOS settings or the settings would be an issue, but a simply battery pull would fix that. Hardly ever does a BIOS get corrupted on it's own. If you're not writing to the BIOS, which only happens with flashing the BIOS, and usually won't corrupt on it's own, OC or not.

In my experience, what causes this: Their is a circuit on the motherboard that detects when the power button is pressed. This sends a signal to the chip that grounds out the green wire on the PSU to the ground and starts up the boot up sequence on the board. I've seen many, many, many boards have this circuit fail.

Sometimes to test this, you can use a paperclip and ground out the green wire and a ground pin while the PSU is connected ot the motherboard, and then press the power button and see if you get a boot.

I take no responsibility for you doing any damage by suggesting the above, but since you're ready to rip out a BIOS chip and flash it, at least my suggestion you can do right now and may help diagnose it.

I've been trying that. The PSU fan start up. but no beeps. I've been trying to start it by shorting the two pins that the power button connects too but nothings working.

This is how I've done it before. Short the green/ground and keep it shorted. Then press the power button on the case. You can't just touch the green/black, you need to keep the connection.

Also, I would assume your CPU has built on video, so take out all the GPU's.

It does not. It's a i7 2600k. So should I leave the RAM in also?
