So I just updated the BIOS on my P8Z77-V Pro to version 1015, rebooted and configured my settings, saved and reset just fine and booted into windows. I then shut my computer down after about an hour to move some fans around and when I go to boot up now after a few seconds the computer will just shut off or reset. Sometimes it stays on for a while but I get no video out at all. The instructions for USB BIOS Flashback in the motherboard manual suck and I'm not sure how I can fix this.

Totally reset your CMOS

Step 1: Turn computer off and unplug the power cord from the PSU

Step 2: wait 5 min

Step 3: Clear CMOS jumper keep it on clear for 10seconds, then put CMOS jumper back to its default position.

Step 4. Take out the battery on the board for 5min.

Step 5: Return battery to its socket, Plug back in the PSU power cord and turn it back on.

Hope this helps

Still doesn't seem to work, system powers on but still no video from my 7970 or integrated graphics. :/

I'm guessing I need to reflash the BIOS somehow.

This thing happened to me too. But mine stays ON, there is just no video. No beeps nothing ... fan stays on ... tried to click mem ok ..still nothing. Not like the OP, mine didnt even boot to windows right after flash. I was in pure stock when thia happened.

I tried removing battery, cmos reset and that jazz .. still no go.

This board looks bricked in my opinion.

Is there a fail safe method to go back ... if yes .. how can i even do that since it does not give me any video.

Please help

Edit: my sig is old i havnet updated it yet. I recently bought 3770k plus the p8zz7-v pro

I fixed mine, turned out to be two of my RAM sticks. I had some old OCZ 10666 RAM, maybe ASUS removed support for the RAM I have. MemOK couldn't fix it either.

thanks .. im not home yet but ill try that. However, i all have ripjaws

so good luck to me

 

[keplenk]

oh well, after I flashed I saw the CPU_LED turned on (RED).

Could it be the CPU or mobo? I don't have any other cpu to test it with

I tried reseatting .. still no go

I'm having a similar issue with my P8Z77-V Pro

Flashed the BIOS to 1015 today, in an attempt to squeeze in some overclocking stability.

With SSD as priority boot device, I get stuck in a black-screen reset loop, however I am able to interrupt it and successfully get into BIOS.

The BIOS appears to be in good working order, information shows that the update was successful, I can tweak settings, SSD is recognized, etc.

Forcing a boot from the SSD in BIOS gives me the same black-screen loop.

I can boot from an external DVD player using a Windows 7 install disc, but after initial loading is done and the GUI appears, I lose mouse/keyboard input. Very strange.

As of now, I've only tried re-flashing BIOS version 1015, unsurprisingly with the same issues.

Is clearing the CMOS via battery removal / jumper switch still a logical troubleshooting step in my scenario?

Also, I'm using a 4x4GB Corsair XMS3 kit which had no problems booting prior to the update, haven't reseated or adjusted the RAM modules in any way, would this be worth trying in my scenario (my hesitation is because of a massive air cooler which must be removed to access the RAM)?

Before I try going back to an older version, was wondering if anyone has any other troubleshooting suggestions for my scenario.

Thank you.

**UPDATE** :
I flashed back to BIOS 906, problem persisted.
Reset CMOS (jumper + battery) with no progress.
Reseated memory, progress!!!! SSD still won't boot up, but external DVD player w/ Windows disc loads properly with mouse/keyboard input. For the heck of it, I'm reloading Windows onto the SSD to see if that does anything. Otherwise, only option I can see before warranty support is to continue incrementally stepping back the BIOS version.

**UPDATE 2**

After reinstalling Windows 7, SSD will now boot correctly to OS.
During the BIOS flash I left the SSD plugged in, which is pretty much against best-practice policy. Doing so must have corrupted my OS data.
Went back up to 1015, reinstalling everything and back to benching, hopefully with some better results!

I know you've fixed it, but I've found that only the vga socket works on booting on the mobo, hence i'd end up doing 'silent' boots where I can see no progress. Going to wait for a few more versions I think.
