recently i had to change motherboards because my old one no longer works (thanks to my cat) computer has been working fine for ~2 days, went to boot today and the mobo (Gigabyte Aorus Pro z690 DDR4 wifi) is displaying error code 96, and when i checked the instructions it said 96 = "assign PCI Device Resources". my keyboard/mouse wont light up and i wont get a display. I tested by removing my GPU (MSI 3080 10gb) and then reseated the SSD (970 Evo plus) and booted with no GPU installed off the MOBO graphics, PC booted everything worked. Plugged the GPU back in and same error occured. I then plugged the GPU into another PC and that PC worked fine, with the GPU appearing in BIOS. i have uninstalled nvidia drivers and checked for the standard windows drivers, none of these worked and the mobo will still display code 96. i can still use the computer without the gpu plugged in, any help would be greatly appreciated. Update: tried reinstalling Windows... still showing 96

Ok so i got an old pc that i found laying around at home, its got an i7 2600, 8gb ddr3 ram, ati radeon ( not sure which one) and a 1.5 rb hard drive, im thinking of upgrading all of this (maybe not the gpu) how ever i dont have a monitor yet, i think i might get one off my friend. Anyways is this a good PC to run r6s on any settings idc? Edit Oh and is got a 250w psu i think i saw

Ok, so my friend is sellung me his 1050 with low miledge for 130aud, all i have is an old hp pavilion hpe with core i7, 8gb ddr3 and an ati radeon hd 5570?? But with no monitor. BIG SAD ??? I this a good deal?
