Hello,
my product Nr. is B5G74EA3#BCM, with new power supply (Seasonic Energy Knight SS-500ET).
My PC had no HDMI output, so I've installed video card ASUS ATI Radeon HD 5670 (about 4 years-old).
After its installation, when I switch PC on, this POST front power LED and audible code probably occures (according to manual): "Red Power LED flashes six times, Beeps stop after fifth iteration", indicating pre-video graphics problem (?).
Then PC go on working normally, with no visible problems or unexpectedbehavior.
Any idea what should I do to solve this problem?
I tried to remove the card and to install it again, but with the same result as above.
Or should I try to use another video card?
Thanks
