Hello people,

I've hit a bit of a pickle really and when I came across this site I figured it was time to ask for help.
I am currently trying to upgrade my graphics card from a nvidia GT9800 to a Gigabyte (nvidia) GTX560
However when I start up my system I get a 1 long burst and 2 short from the motherboard. Now this suggests an issue with the graphics card.
Ive done the typical unplug - replug, and made sure all connector leads are installed. However no matter what I still get the same. Any help or
suggestions would be greatly appreciated.

My system is:

Windows 7 64bit
10 Gb DDR3 1333 Corsair Ram
500Mb Western digital HDD x 2
Motherboard: gigabyte ga-p55-us3l

The motherboard and all sockets are working fine and have been tested with a few spare graphics cards. Same for RAM slots.

I believe that your current PSU is at fault here because you try other graphic cards and they work

You need two PCI-E connectors for that card also a min wattage of 450w to run the card

99 CMaximum GPU Temperature (in C)
150 WMaximum Graphics Card Power (W)
450 WMinimum System Power Requirement (W)
Two 6-pin

Most people will get 650w to 800w for a power supply

The wattage maybe the problem or the card itseft

I cannot tell you which one though until we get more information about the power supply
