Display artifacting (I think) rendering pc unusable, how to repair?

HP Recommended
Pavilion p7-1047c
Microsoft Windows 10 (64-bit)

This is a HP Pavilion p7-1047c desktop. The only upgrade has been slightly higher RAM. The machine was bought in 2011. Aside from RAM going bad (!?) In 2014, it has been reliable until now.

The other night, the display went haywire, large checkerboard pattern with horizontal lines and it's bright, painful to look at. To troubleshoot, I powered down and hooked up a different monitor with a new dvi cable.

Upon stsrtup, the display looks great on the password login screen and then reverts back to checkerboard nastiness. Can't use the machine at all, I can see mouse pointer but it will not respond.

Looks like my graphics card is broken. I thought I'd simply swap it out, but it is integrated. There is an expansion slot which I think can be used for a video card. Does anyone know if I can put a new video card in the slot and bypass the seemingly broken integrated graphics card? Or do ok need a new ipisb cu motherboard? Thanks.

If I need a graphics card, I understand I'll need a specific type for a 2011 era machine. Any constructive advice is appreciated.

I have gone through your Post and I understand your concerns


Since the Computer is unusable the moment you Sign in, I suggest you perform a Reset first before you go ahead with adding a new Graphics Card


You can refer to this Link: for help with the Reset. This will ensure it's not a Graphics Driver issue


Your Computer does support PCI Express x16 Graphics cards. The computer will support any latest PCI Express x16 Graphics cards. The rest only comes down to the cost and the purpose of upgrading the Graphics Card example if it's for Gaming etc.


Hope this helps


Thank you and have a great weekend 😊
