bob16314Run Display Driver Uninstaller (DDU) in Windows Safe Mode and use the "Clean and shutdown (For installing a new graphics card)" option for removing the AMD driver..Then install your new graphics card and the Standard NVIDIA Graphics Driver.

kevinc313From what I gather you've installed a 2070S FTW3 Ultra+. The 100% power limit is 260w and the 130% power limit is 338w. This is the same as a typical A-chip 2080 Ti, which is a very serious amount of 12VDC power. You should have a 650W power supply minimum with two entirely separate 8-pin power cables from the PSU to the card. If you're running off the stock XPS 8300 psu (430w?) with a single daisy chained cable you might be ok-ish at stock 100% power if your CPU and the rest of system doesn't draw much of power, but it's not optimal.
kevinc313That PSU came with a pile of GPU power cables.
Cool GTX https://www.evga.com/prod...aspx?pn=120-GP-1000-X1 should have 6 - "GPU" --> PCIe power cables --> the (4) 650 are single ended PCIe Cable 4x 650mm (m), 2x650mm, 750mm(m)
