put in graphics card bt only black screen wen turn on!!

[nnjc]

i have just put in a graphics card (asus EN9800gt 512mb hybrid power) and wen i turn it on all i get is a black screen! what could the problem be?
I have a 500w pc and its a very brand new pc with 64bit windows 7 and intergrated grraphics.

also note that the first time i put it in i forgot to put in the 6pin adaptor and when i turned it on it made a big beeping noise. could this have stuffed up the card? becoz wen i remove it, the pc works fine

help please???

i think ive had this problem before. the beeping sound you heard was I believe the POST telling you that something is wrong with the graphics card. This is expected since you forgot to plug in the power. For me, it turned out that my power supply was a bust. Everything else turned on fine but there was never anything on the screen. Replaced the psu and everything booted up. See if you can find a replacement? Your wattage seems to be fine.

Stupid question time, did you remember to attach the monitor cable to the new video card from the onboard video?
