Is the graphics card faulty?

[ghandiripper]

Put together a new build yesterday and keep getting faults:

Asus Rog strix B450-F gaming
Ryzen 5 3600
Arctic Freezer 34 esports duo cooling
Corsair Vengeance LPX 2 x 8gb 3200Mhz
Zotac GeForce GTX 1660 SUPER Twin Fan 6144MB GDDR6 PCI-Express Graphics Card
Seasonic GX550 80 plus gold PSU
Crucial ssd
Toshiba 3tb hdd
Win 10 Pro

Monitor is connected to the graphics card HDMI port (it also has 3 displayport). Initially appeared to work fine, with no errors. Tried to get into BIOS using F2/DEL keys but couldn't get in. The monitor display was blank (showed no signal) until windows desktop was displayed.

Then started getting POST beeps 1 long 3 short (memory). Reseated the memory sticks in A1 B1 then one at a time then both back in A2 B2. Had 1 long 2 short POST beeps on one occassion. Motherboard error light sometimes stayed orange indicating a memory error. All this time still couldn't access BIOS or see the boot screen; as before.

Also had the USB keyboard and mouse not coming on properly when booting. Used a PS/2 wired keyboard and that didn't work correctly either; when trying to access BIOS with F2/DEL keys.

Took out the graphics card and tried a 1050 Ti card in the same PCIE slot and was able to see the boot screen and access BIOS. The USB keyboard and mouse work correctly as well!

Is it likely that the 1660 super is faulty and causing other random problems?

Is the motherboard's BIOS fully updated? Is DOCP / XMP on or off? Have you tried the Zotac in the x8 slot? Have you tried the DIMMs separately?

Thanks for responding.

BIOS is updated to latest (3003); it came with 2901 installed. DOCP is currently off; it was on but I cleared the CMOS before I thought to swap the GPU. DIMMS were tried separately in slots A1 A2. There are only problems (currently) when the Zotac card is plugged in and its only been plugged in the PCIE_X16_1 slot (so far) with Link speed in BIOS set to AUTO (not GEN1/2/3).

The PC 'appears' to be up and running fine at the moment; my stroppy 19 year old is currently playing Counter Strike Global Offensive on it and there 'appears to be no problems'.

The PSU is a hybrid but is set for fan on all the time. Voltages are shown as correct in Asus suite but latest (stable) HWINFO64 shows 12v as about 10V; under ASUS WMI. I thought it might be the PSU so swapped it with a BeQuiet system power 9 500W (less than a month old) and that has the same voltage readings in Asussuite and HWINFO64. I therefore assumed the ASUS WMI info in HWINFO64 is wrong.

Have you tried putting the Zotac back in? Just in case there was dirt on one of the connectors. The only other thing you can do is try the card in another system.
