Hey guys.

I have always had my suspicions, but I am now pretty certain that my motherboard is slowly going up the crapper...

If you look through my past threads, you will see the problems I have had with my computer in detail, but I will make a brief summary of them here...

On day one when I was building the computer, I plugged the USB front panel into the firewire header, and burned out a chip at the bottom of my motherboard, thus invalidating my warranty, and rendering fire-wire useless.

After then the next problem I encountered was overclocking. How the system reacted to overclocking made absolutely no sense. It would not boot with a 46x multiplier or a 48x multiplier, but it would boot with a 47x multiplier while everything else remained the same.

The RAM does not overclock at all, not even a little bit, it just fails and re-boots and hangs until I clear CMOS.

Sometimes from early on up until recently, the system would turn on, pause on an F2 error (recovery process started), fully reset itself, and then hang on a 70 error (south bridge DXE initialisation is started). The system would boot fine after a hard reset.

USB 3.0 has never worked properly, and I avoid the USB 3.0 ports on the back of the machine for anything other than devices which require power and nothing else (monitor backlighting for example) I tried changing BIOS settings and/or re-installing drivers, which temporarily fixed the issue, but soon enough the ports had stopped working again even with the changes.

The system started to hang on a 98 error completely out of the blue on startup, I fixed this by turning 'USB Legacy support' off. No new USB deviced had been connected, it just started completely out of the blue.

Random 0x124 BSOD's started to occur while stress testing, gaming or watching HD video, I have played around with DRAM voltage and VTT voltage, tried different RAM, increased the VCORE, decreased the VCORE, and even decreased the multiplier and tried various combinations and other things as well but the BSOD's persisted, the only thing that changed relative to the settings was how long it took for the BSOD to appear.

Once (only once) I got a different BSOD relating to the HDD and when I restarted the system the HDD was not detected. I then had to reset again thereafter and everything was fine, the HDD is also completely healthy.

Today after cleaning out my radiator and applying new TIM to the CPU, a problem similar to that which happened with the failed overclocks (mentioned previously). When I turn on the system with the same BIOS settings that have been 'fine' for the 18 months or so I have had the machine, the PC pauses at a 60 error (DXE Core is started), acts as though it has been restarted (fan speed dips and then peaks again) and it hangs on a 70 error. This persists until I clear CMOS, go into the BIOS, re-apply the saved profile, and then save and exit, whereafter the system acts the same but it passes the 70 error and boots into windows.

Sometimes it hangs on a 71 error for a change and then hard resets.

I am now running with stock BIOS settings as I type this, apart from fan speed, and HDD mode...

I have been in denial about the motherboard being busted for a while, because I could always make the little problems go away, and I was/am aware of the fact that the warranty has been voided, and that a replacement would cost a-lot of money and I don't have much money...

So yeah... The motherboard is not quite properly toasted toast isnt it? :(

The RAM has been changed for different RAM, I have had four different GPU's in the system in the time I have had it and the problems are the same, I highly doubt that the PSU, HDD's, SSD, ODD, or sound card could cause these problems, and the OS wouldnt be to blame because most of the issues occur before it has even loaded.

*edit* the machine now appears to start up fine with no modified BIOS settings, but there is still an 05 error which flashes just before power off. (SCSI something or other) not sure if I mentioned it above.

*edit again* on another restart it hung on the 98 USB error with no modified BIOS settings. It seems that the most recent issues only occur when there is a CPU overclock in place.

you should be using the latest bios if you arnt already,tried with one memory stick?

the vengeance ram isnt good for overclocking so id run it at rated speed,i had some it was just basic stuff,i have samsung green now
 
I'm a little bit worried that attempting a bios update would end with me bricking the board because something goes wrong. What with how it is acting etc.

did you do a full cmos clear first? i wouldnt worry as the bios chips pull out on asrock boards and you can buy one pre flashed with the latest bios of fleabay if need be

aslong as you flash it from within the bios and a memory stick your ok,dont flash it from within windows
 
Hmm... Oddly... I don't actually have a memory stick xD
So I'll have to borrow one. My external hdd is NTFS rather than FAT32 as well, otherwise I would use that.

*edit* actually I found one, never mind.
 
Well I have now flashed the BIOS to 2.30 (it was on 1.00 before :p )

I think some of the issues may have been resolved, however the system won't boot into windows with my OC settings now it would seem.
 
you might need to start over as voltages will be slightly different with each bios version

Sorry, it was my mistake, I didn't change a couple of settings to what they needed to be.

The extremely persistant/annoying overclocking issue seems to have gone now (woohoo) and the BIOS looks nicer (woohoo?) but I still get a momentary hang on A5 (IDE detect I believe) for about two seconds which I didnt have before, and the machine still displays that 05 error just before it cuts out after I shut down.
 
whats 05 error in the manual? any usb devices plugged in? cant think why its doing that

apart from that is the board/oc stable now?

05 is 'OEM initialization before microcode loading'.

Looking over the internet other people with this problem have the system hang on shutdown, but mine just passes in in an instant, but it is displayed there momentarily.

USB devices are:

Keyboard - Logitech G510 (top/black USB 2.0 port)
Mouse - CM Storm Sentinel Advance 1 (top/black USB 2.0 port)
Webcam - Microsoft LifeCam Cinema (middle/red USB 2.0 port)
Wireless - TP Link TL-WN822N (middle/red USB 2.0 port)
Other - Antec monitor backlighting (power only - bottom/blue USB 3.0 port)

Nothing connected to USB front panel.

Legacy USB support is disabled in the BIOS because of hanging on 98 on startup (console input devices detected).

I think the board is stable, I need to stress it and test a few things before I can be 100% sure.
 
it could be just the way that bios version is aswell

can try swapping things plugged into usb3 ports to the usb2 ports,sometimes usb3 can cause problems with shutting down apart from that idk what it could be
 
Ok, now it is stable (yay) however when I turn on the PC I still get that brief hang on an A5 error, and the on board speaker no longer beeps. And that 05 error flashing up on shutdown is still there.
 
Been maxed out on the CPU & GPU (either by stress testing or folding) for over 90 hours straight now. So it is safe to say that things seem fine. Nothing in the PC goes above 60°C :D

Is it possible that the A5 hang could just be a trait of this BIOS revision? The sequence of checks that flash through on the debug screen on startup are different now as well. With different codes and such.
