Hi, i've recently had trouble with my PC not booting from when the HDMI is plugged straight into the graphics card. However, if the HDMI is plugged into a USB port the machine will boot. This is the second Graphics card i've received off Dell. It is a GTX 660 & the machine is a X51 R2 (Early 2013) Windows 7.

I've been on the phone to Tech Support today and we re-installed the operating system along with all drivers, the graphics card even passed the stress test & did not seem to be over heating etc once the benchmarks were running. I will be phoning Dell on Monday when the lines re-open but does anyone have any solutions for this or what it could possibly be?

Thanks in advance
