Alright so awhile back a friend let me try out his graphics card in my computer to see if i liked it and it worked great and ran games really well. (Radeon 5450) Well make a long story short me and him traded some things and i ended up with the 5450 and i tried putting it in today and i did everything the same way i did before but all i get is a blank screen and my monitor says "There is no signal from computer." I have tried everything to fix it and get it to work but it just wont. It ran just fine the last time i used it and i had no trouble with it but now i have been sitting at my computer all day trying to get it to work but it wont. PLEASE HELP!
