Hey guys,

Recently I had a new graphics card (Geforce x460) installed along with a new PSU (Had a specialist shop do all the work) but I've had a problem since.

To get a picture on my monitor, I need to turn on the PC, shut it down with the power button on the PC, then turn it back on, only then will I get a picture, and I have absolutely no idea why!

My PC had integrated graphics, however I cannot see it in "Device Manager" so I can't go to disable it, possible it's been uninstalled, not sure if that would cause a problem.

In BIOS, i've changed the following settings:

"Onboard graphics controller: Disabled" (HOWEVER, everytime I reboot it turns itself back to "Enabled" , again, not sure why... main problem maybe?)

"Primary Video: PCI-E"

"Power up by PCI-E Devices: Enabled"

And this has changed absolutely nothing.

I've tried other things as well. like getting rid of the integrated chipset drivers etc, but no luck!

Checked all cables, etc.

Seriously tearing my hair out over this.

PC is a Packard Bell Ixtreme M3720.

Any help would be greatly appreciated!

EDIT: Motherboard is Packard Bell MCP73PVT-PM, if that helps.

Are you sure that your mainboard and graphic card compatible together? If yes and it turns Enabled (the O/B graphic settings) your motherboard doesn't recognize the new card to open itselves. So it enables the O/B card to run.
You can reset your bios and clear cmos to test it what happens.
You can uninstall O/B cards drivers and reset to see what happens.
You can start with Safe Mode to see what happens and install new gp's drivers etc..

I've uninstalled all old drivers, then reinstalled new ones, both in & out of safe mode, no luck with that.

Motherboard & video card are definately compatible.

Clear cmos? What would that do exactly, and how would I do that? sorry, i'm terrible with computers, like I said, had to send my PC to a shop to do a 20 minute job for me because I just don't have a clue!

As you said, you did all what have to do. Bios settings etc.
Another one is the graphic card can be broken. There was a topic like yours (same problem) and I told that I'd same problem before. It was a new card and results was same as yours. I gave it back and bought another one and it was worked correctly without configration. No bios setting, PCI-e > PCI > IGD or making disable. System removed the O/B in Bios auto.
Clearing Cmos is a way to make your bios factory settings.

Thanks for the responses Latte!

I guess if all else fails then that would be the only option, but I can't help but feel that there's a simple fix for this (hoping mostly). The fact it works after a reboot and that I can keep it on for hours with absolutely no problem until I turn it back off gives me some hope at least. But like I said, if all else fails I would just send it back to the shop that installed my hardware and let them deal with it, only problem is I can't do that for another month or so for various reasons...

Wouldn't be as simple as needing a new cable would it? I'm using the one that came with my PC for my integrated graphics chipset (15 pins each end) and put a DVI adaptor on the PC end since the new graphics card install, that wouldn't cause any problems would it?

Any more comments/suggestions would be a great help ^^

If the graphic card have same input DVI HDMI etc.. That means you can connect with it;) It can't be about cable because it works same way with O/B graphic card ;)
