I Just bought a Gigabyte GTX 650 Overclock version for my computer, but after installing it my computer doesn't display anything on the monitor. With out the Graphics Card the computer turns on fine with no problems, when it turns on it has a short beep then startsup. But with the Graphics card the computer turns on, the fans are on etc. but there is no beep and the monitor doesn't get any signal. There was no previous graphics card it was just the standard VGA graphics Adapter (in device manager).
I'm using Windows 7 32 bit
4 GB of ram
Intel Pentium D CPU 3.20 GHz
Thermaltake 500watt PSU
I'm sorry if i haven't provided enough information, I'm not very tech savy
