" rel="nofollow - I filled out the asrock support email form 3 months ago and have yet to hear back. I filled it out again and sent another support email before making this post. I am very disappointed they have yet to reach out.
In the meantime, perhaps someone here has experienced a similar issue and can help.
The board is an ASRock x79 extreme7. CPU is an i7 3930k. All other parts have been swapped in and out during troubleshooting (see below for details).
The Problem: The computer works without issue once it reaches the post screen. Typically it gets stuck on code d7 and never shows a picture.
Sometimes it does work though I cannot pin down what is causing it to post or what is preventing it.
Here are some of the steps I've tried: - 6 different USB and PS2 keyboard and mouse in all usb inputs. All work on other systems without issue.
- different pcie slots.
- different graphics cards.
- different monitors.
- different ram.
- removing cmos battery.
- removing and reseating ram/gfx
- reseating mb cpu and main power connectors.
- various hdd combinations on various usb ports.
Sometimes I get different codes after clearing cmos but then after a restart it will revert back to d7.
Usually I am able to get it to finally go to bios after 5-20 tries clearing cmos.
I am just at a loss and pretty much willing to try anything. After the most recent reboot I have spent roughly 1 hour with the system and had no luck. That has happened before though and when I returned a day later 5-10 tries clearing cmos eventually would get it to post.... so I think the system works.
Some other considerations: - Capacitor caps don't look blown anywhere and mb solder points/trace that I can see all look intact.
- I don't think any of the hardware is bad because the system is 100% stable even during stress tests once it boots up.
- Never ran the system overclocked.
- All fans are working.
- Temps are good.
- bios is most recent and the issue didn't start until years after last bios update.
I will try to compile a list of others codes that the board shows and what steps were taken prior to posting those codes.
From a troubleshooting standpoint I am stumped and that is pretty rare for me. Has anyone else ever experienced anything similar or have any ideas?
...And please email me back asrock support. In the past you have been great which is why I've stuck with asrock boards after switching from gigabyte and asus 10 years ago.
