New graphics card - PC not booting

[Danathor]

I own a 6 year old Advent DT1411 with specs:
Afternoon all,

My build is:

Processor Intel i5-2320
Motherboard Foxconn, H61MXL/H61MXL-K
8GB RAM
AMD Radeon 6670 2GB graphics
405watt power supply

I recently purchased the R9 380 replacing the 6670. Minimum power reqs are 500w so purchased EVGA 600w 80 plus. However, GPU still not booting (while switching on - fans and lights)

Is the system compatible? If not - what are issues? Not sure if motherboard issues, PSU or drivers.

Thanks!

Is the card new ?
Have you connected the power cables to the card ?
do you have video signal on any of the video outputs on your computer (both card and those on motherboard) ?

Hi there and thanks for the quick response!

Yes the card is brand new, and yes I have connected it to power (2X 6 pin)

Haven't tested motherboard integrated graphics but the old graphics card still works a treat when I swap it back in for the new one

try some other output on GPU. Try the onboard and check if windows recognized the card in device manager.
try the card in other computer.
If nothing helps, return it as dead

I have just tested : onboard motherboard graphics works only when old graphics card disconnected ; will try with new graphics card plugged in now

Your mobo may need a bios update. See if one is offered.

I might well have to! Although I am suspecting power issues as my computer (with the new card plugged in) will randomly switch itself off sometimes.

Just completed test and the monitor plugged into onboard motherboard graphics does not start up when I boot PC with new graphics card!

than test the card in other computer.
Seems like it faulty
