I recently disabled my integrated graphics card by mistake in the device manager on Windows 10 PC and now I have no signal to my monitor. I found some old threads on here which said to reset the CMOS but I can't seem to get it working again despite following all of the steps to remove the battery and take the pins out for a few minutes.

I also can't boot up in safe mode to re-enable the setting and I currently have no access to another PC to create a Windows repair disc. I'm tearing my hair out here lol.

If I remove all power sources and reboot the PC, it does ask me to press F1 to load BIOS settings but when I enter the integrated components sub-menu, the on board graphics card is greyed out and set to ‘Enabled’

Anyone have any ideas what to do next please?

It gives me the option to restore defaults on the BIOS but it doesn't appear to make any difference after multiple failed attempts. The option to enable or disable the onboard graphics is still greyed out.

As for the CMOS, I've tried moving the pins as per the guide, but I don't get any power to the system unless they stay in their current positions. The battery has been removed several times and there are no leads connecting to the battery that I can disconnect

You can try getting into advanced startup options their is a command like f11 on startup that boots you into it. You'll have to look up the correct function key and it has troubleshooting options as well as a feature to restore from the last restore point. Hopefully this helps. Sorry about that dude. You would use that function key where you said it says press f1 to load bios. Maybe some further research will be required but this might fix it.

Make sure to download nvidia geforce experience to get the proper drivers when you get there. Also try checking to see if it is displaying in the device manager. But one step at a time you'll fix it.

Ahh I see. Do you have a graphics card or have you been using the on board graphics? The answer above me mentions installing NVidia Geforce but I don't see you mentioning you have graphics card. Please clarify.

If it's permanently enabled (greyed out), then it means it's not detecting your graphics card (if you have one).
1. Remove the graphics card and attach the display cable to the mobo
2. If the card is already plugged in, make sure the cable is plugged into the graphics card and not the mobo.
3. If it still doesn't work, check the graphics card is powered on. Swap the connectors from the PSU.
4. Make sure PCI is enabled in BIOS if you have a graphics card. Also look for an option "primary display card" or something similar.

You might just have to re-install windows if this still doesn't work. BTW, windows doesn't load at all right? That's when the screen goes black?

I only have the onboard graphics card installed. Sorry I should have made that a bit clearer in the first place. That's what's even more frustrating...the fact I actually disabled it knowing deep down it would cause a problem lol. I was only trying to change setting for a new monitor that was stuck on 800*600 resolution!

As for Windows loading up, it only shows the BIOS menu once I've removed the battery or power supply. Other than that, my monitor just says no signal and stays black.

I guess my only option now is to find or download a repair disc? Was hoping to avoid that but if it's my only option....Thanks for the replies though

Wait what?

If you messed around with the resolution then it could be that you set up a resolution your monitor can't handle. When the computer is on and the monitor is plugged in, remove the display cable and put it back in. Other than that yeah you might have to recover or reinstall windows. If you have a graphics card lying around, that'll help.

No I definitely disabled the onboard graphics. Stupid, I know. I was getting frustrated not being able to change the resolution in Windows so for some reason I thought disabling, and then re-enabling the graphics might work. Doh.

I still haven't found a solution and can't risk a new install as there's files I need on my HDD.

Now trying to figure out what type pf graphics card i would need to buy... but without my PC i cant find the specs. Im running a fairly low-end home PC from a few years ago but it's one of those compacted systems and I know certain cards won't fit.

Do you know a way I could find this out please?

Ok so after a couple of days I finally managed to download and burn the Windows 10 ISO to DVD in hope that I could boot from the disc and re-install, or at least repair, the system. However, when I choose to boot from CD/DVD drive, a command dialogue appears and flashes a little underscore for a few seconds, then loses signal again and I'm back to square one with no screen.

Can anyone please suggest any further ideas that don't include buying a new graphics card as that isn't an option right now...thanks...
