Hello, im new to computer maintenance and trying to learn all I can. A friend recently gave me a computer he found on the side of the road, the case was smashed up a little but it still runs that I know of. Only problem is, I cant get the graphics card to load up. When i boot the PC up, it wont display anything on the monitor. I have installed a new card but it still wont work. The pc is a CTG acer intel triton. (this is all I could find on the PC) It has a HP diskdrive in it. It also has dual power in the back, 1 normal plug in and then 1 that looks like the power cord u plug in. In the front of the PC it has 3 buttons, 1 is a power button, 1 restart and I don't know about the other 1. From what I can see on the motherboard, it says AOpen (i guess this is the brand..) I can post pics of this PC if needed. Please help me solve this problem, if im not specific enough just tell me and ill post more.
