    Default Z75 Pro 3 Mobo BIOS Update fail - blank screen

    Hi all, this is my first post and would really appreciate any help.
    This is my first build since the days of 486's, probably about 20 years ago, so I am certain I made dumb (and careless) mistakes.

    Just got all the parts today. Took a few tries to get OS installed, as I kept getting BSOD. After a few reboots got the OS installed, but computer would occasionally restart and I couldn't see why. As far as I could tell power was consistently on. Thought I would be smart and update the BIOS. Got the version 1.5 windows update from the ASRock site, and update was going OK until screen blanked out. It's still blank. And now the power button doesn't even work.
    So, two questions:
    1) Is there any way to salvage this Mobo? Or is my best bet to send back to Newegg?
    2) Is there something else that might have been causing those spontaneous restarts?

    Specs:
    Mobo- ASRock Z75 Pro3
    BIOS- 1.40 (tried to update to 1.50)
    CPU- Pentium G630
    RAM- GSkill Ripjaws DDR3 1600 2 x 4Gb
    VGA- Radeon HD 6670 Gigabyte GV-R667D3-1GI
    HD- OCZ Agility 3 60 Gb AGT3-25SAT3-60G

    Any help is very much appreciated! Thx!

    Any chance the bios flash switched your primary video back over to onboard? try moving your monitor over to that.

    If that doesnt help. simplify.
    remove power first, remove the radeon and maybe the hard drive. clear the cmos. just keep enough connected to POST.
    That motherboard is supposed to have "crashless" bios, that will resume a failed update. plug in a USB key with firmware and boot the system.

    To bad you didn't use the BIOS flashing feature run from the BIOS itself, I've found that to be very dependable.

    Your SSD may be contributing to your BSODs, as it is not known for its great stability. Did you install all the drivers after you installed Windows?

    As synack wrote, check the manual for the procedure for the crash free BIOS recovery. You must use one of the USB 2.0 ports, and only a USB 2.0 port, on the rear I/O panel for the USB flash drive with the BIOS file. You must remove all power from the board when trying to reset it, power supply off and unplugged from AC power. Clear the BIOS with the boards jumper, and even removing the boards battery.

    If the BIOS was completely ruined, you can get a new BIOS chip through ASRock by contacting their customer service.

    Thanks Syn and Parsec for your quick responses. Still haven't fixed the problem but have not yet tried to use the USB stick method you both mentioned.
    Parsec - Disappointing about the SSD if it is the issue, but thanks for advising. Definitely tried to update drivers for SSD, but remember reading something about not being able to update for a system drive. Thanks also for advising regarding the CMOS chip through customer service.
    Syn - I tried switching the monitor to the analog on-board D-Sub VGA port. The monitor recognizes that it is plugged into a port, but I just get a blank screen, as with the Radeon DVI port. I plugged my TV into the on-board HDMI port, and didn't even get the TV to see a signal, although that could very well just be the TV.
    At this point I have unplugged everything from Mobo, including RAM and SSD, except: CPU and Chassis Fans, Mobo Power, CPU Power, and System Panel Header. The CPU fan, both chassis fans, and PSU fan are going, and the power led is on, but no other signs of life. I have tried clearing CMOS by moving the jumper on the cmos clear header (haven't moved battery yet, will try USB first). No luck.
    Looking up how to do the USB Bios update now. I don't see instructions regarding same in the guide that came with the board. Incidentally, the rear panel USB ports don't seem to be providing power to the mouse and keyboard I have plugged into them; I hope that won't affect the USB firmware update.
    Thanks again, and I appreciate any other thoughts while I work on this issue.

    Lol, I hope you meant you reseated the RAM. Nothing will work without it. All you need to power up is well, power... video (preferably just the onboard for now), CPU w/fan, memory and a keyboard.

    Do you get ANY life when you power up? Do you get fans? Does that mobo have an internal speaker? I see a header for one in the far bottom corner. Happen to have an internal speaker laying around? Maybe you might get some beeps or blips or something.

    Oh another question, Do you have any other RAM laying around that'll fit this board? I don't usually express brand preference, but I have special dislike for gskill memory. Been burnt 2 out of 2 times with crappy ripjaws. Both exhibiting random crashes and "funkyness" that was resolved by replacing them with other brand RAM. I ended up tossing them in the garbage lol...
    I hope this doesn't anger the forum owners seeing as G.skill's tech support is on here.

    Yeah, gotta have RAM in there, use slots 2 and 4 with two DIMMs.

    Good idea about the speaker beep codes synack, there is a header for a speaker, and my ASRock board (really the BIOS) will produce beeps.

    No power to the keyboard or mice is strange, again use the USB 2.0 ports, if the ports on the I/O panel are blue, they are USB 3.0 and won't be active during POST.

    Since this is your first build in a while, just to check, what power supply are you using? Does it have the extra four or eight pin cable for CPU power, than connects to the mother board, as well as the 24 pin main cable? Gotta have at least a four pin cable for that extra power. Be SURE that the cable is NOT a video card power cable, it will likely fit but is NOT the same.

    synack, curious about your G.SKILL memory, that's all that I've used for years until I started using the new Samsung. Never a problem, but doo-doo occurs.

    Thanks again for your responses.
    Shows how much I know... Thought maybe I could POST without ram. Had tried reseating earlier. As it did nothing, I took the RAM out completely. Put one DIMM back in and now the rear panel USB powers my mouse (as long as it is plugged in when I turn system on). No indication it is reading the USB stick or keyboard.
    Only other sign of life is all fans on (psu, cpu, 2x chassis). This old machine I'm using right now probably has a PC speaker somewhere, but half the board is covered by the CPU heatsink and I don't want to mess with it being that its my only working machine. I tried plugging external speakers into the rear-panel audio ports and front panel port (after plugging front panel back into HD audio header) but haven't heard anything.
    I don't have any other memory that would fit this board, but the Ripjaws seems a more likely culprit for the weird resets and BSODs I was getting that spurred me to update the BIOS...

    Hey, I don't want to incite hate against gskill lol... I was only relaying my experience with them. But trying dif memory is a good idea anyway, regardless of manufacturer if you are having these sorts of problems.
    I don't think you can run a single dimm on that board, I could be wrong, but I believe you require 2. But it's interesting that you get *some* life with only 1 dimm in. if you had a speaker, you would probably get a "memory error" lol. see if you can't borrow a set of ram from someone for testing. i'd hate for you to need to go out and buy RAM to find out that wasn't it.
