I had problems with bios battery which I replaced kept losing settings all time. I don't think there is much wrong with your setup check the bios settings again. I have never updated bios on motherboard perhaps there is something in any updates released?
I did have problems in windows when it took on the creators update. I am now on blockchain drivers 1 upgrade before creator. Had issues like you described on start menu etc.
Topic: suddenly no video from IGFX (Read 115 times)
well thing is i had normal access to bios when my cards were modded, all this happened after i unplugged the mobo from the power cable to move it to the rig frame.
I have the same on on my TB250pro doesn't really bother me to much if the 6 x 570's I have when running normal bios I can access bios, but if modded I only see display when I get to windows. I now have 6 1080ti's so making a 12 card rig which of course have no bios mods. I can see bios now all the way through.
hi everyone im new to the forums, i searched a bit and couldnt find any info on my situation which is kinda weird, this gonna be a long post so here we go, ill start with my setup
TB250BTC (B25CFB29 BIOS)
4GB Ram
4 Aorus rx580 8gb ( 23 august blockchain drivers, bios flashed )
1 sapphire nitro + rx580 8gb ( 23 august blockchain drivers, bios flashed )
2 EVGA B2 750w
1 Add2psu adapter
5 random risers (all working properly)
1 120gb ssd
1 Celeron G3930
windows 10
Everything was working fine on my test bench, and i was getting video from de IGFX, when i turned everything off and moved the set up to the mining rig frame, i couldnt get any video signal from the iGFX so i plugged the dvi cable into one of the cards and got a video signal, used atikmdag patcher and restarted to check BIOS settings (maybe the igfx got disabled somehow).
After restarting i couldnt get into BIOS, screen stays black until windows is loaded. Unplugged every card and used a spare gtx1060 on the 16pcie slot of the mobo, plugged dvi on the 1060 and got a video signal like it was the igfx i could see the pc booting and bios screen etc.
Checked BIOS settings everything was how its supposed to be, IGFX was primary etc..
Unplugged dvi from 1060 because i needed to move the monitor, plugged dvi back in and got no video, restarted pc and still no video. i had to reset CMOS with the card plugged in to get a video signal. Which was being recognized as the IGFX.
Took off 1060, plugged all risers again and restarted, no video signal from either mobo or gpus. Reseted CMOS with all cards plugged in, i plugged the DVI into the riser that was on the 16x slot and got a video signal. But only when windows loaded i couldnt access the BIOS, when windows loaded i noticed on the device manager i had some PCI controllers not being recognized, like the drivers some how got corrupted or uninstalled, downloaded them and installed them without issues , restarted pc (dvi on 16x riser gpu) got video signal only when windows loaded, windows was buggy and slow and couldnt use start menu so i did this to fix it:
Regedit
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WpnUserService
Double click on the value (DWORD): "Start"
Change the "Data" to 4 then OK.
Reboot
After all this the computer seems stable, no windows bugs or slow windows proccess, BUT i cant manage to get a video signal from the IGFX and i cant access BIOS, the only reason i can figure out is i somehow fried the igfx chip on the G3930 maybe by static or idk.. thing is if i unplug the dvi cable for some reason, i have to do a CMOS reset again to get a video signal from the GPUS.
