Question New GPU - can't get past BIOs / no signal detected

[TheConsiderateIlliterate]

Hello.

I purchased a new GPU (AMD Sapphire RX 6700 10GB) and am struggling to get it to work with my secondary PC. The fans spin, I can get into/past BIOs, but after that it's just blank until a no signal message pops up. No loading into windows. I've read similar threads, tried every solution I could remember but no luck.

Specs:
Mobo: ASRock Fatal1ty Z370 Gaming-ITX/AC
CPU: Intel i5-8600k
PSU: EVGA SuperNova 750 G3, 80 Plus Gold 750W
GPU: Sapphire Radeon RX 6700 10GB (new card)
Windows 10
2 SSDs
2 case fans
No RGB lights or anything. Running this thing pretty bare bones.

What I've tried:
- performed the correct DDU uninstall process (boot in safe mode, select option of new graphics card where it cleans all drivers/files and shuts down)
- updated motherboard BIOS to latest non-beta BIOS
- reset CMOS
- changed PCIE1 Link Speed in BIOS from auto to gen 3, rebooted, same outcome, changed back to Auto (I read this somewhere the mobo pci gen version may be an issue? anyway, no luck)
- used a display port cable / different ports
- used an HDMI cable
- confirmed the new card actually works by installing it into my main rig (the card works)
- installed my primary card (6900xt) with the same no signal outcome (somehow this gave me comfort because it getting past BIOS would leave me with more questions than answers)
- re-installed my existing card in the machine (amd rx 470 4gb) to make sure that still works - it still works.
- swapped out the PSU (even though already I'm over the minimum PSU requirement with my 750w) with another functioning 750w I have PSU, no luck. Also the PSU was recently powering a 1080ti which uses more than these cards so didn't think that was the issue.

Weirdly enough, out of the 30+ times I've tried getting the PC to boot, two of the times it actually did boot. However, upon restarting, back to no signal.

I'm stumped.

In all that I see no mention of having installed the latest AMD graphics drivers? Perhaps that is just an oversight?

If so, I would try doing a hard reset WITH the new card installed. It is NOT the same thing as just "resetting the CMOS". It often works in cases where simply using the jumper or only removing the battery then putting it back in, does not.

BIOS Hard Reset procedure

Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.

Remove the motherboard CMOS battery for about three to five minutes. In some cases it may be necessary to remove the graphics card to access the CMOS battery.

During that five minutes while the CMOS battery is out of the motherboard, press the power button on the case, continuously, for 15-30 seconds, in order to deplete any residual charge that might be present in the CMOS circuit. After the five minutes is up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.

If you had to remove the graphics card you can now reinstall it, but remember to reconnect your power cables if there were any attached to it as well as your display cable.

Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.

Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP, A-XMP or D.O.C.P profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.

In some cases it may be necessary when you go into the BIOS after a reset, to load the Optimal default or Default values and then save settings, to actually get the hardware tables to reset in the boot manager.

It is probably also worth mentioning that for anything that might require an attempt to DO a hard reset in the first place, IF the problem is related to a lack of video signal, it is a GOOD IDEA to try a different type of display as many systems will not work properly for some reason with displayport configurations. It is worth trying HDMI if you are having no display or lack of visual ability to enter the BIOS, or no signal messages.

Trying a different monitor as well, if possible, is also a good idea if there is a lack of display. It happens.

Thanks for your response. I tried with and without the drivers, as well as the guidance you provided. No luck.

But good news. It’s working now. The last thing I could think to do is reformat and start fresh with the card installed. We’re in business now. Many thanks!

Cool man. Glad you got it sorted.
