So recently I've picked up some parts on eBay, for a budget build. I got a e8500 dual core processor and a gtx 750 SC, to put in a Dell optiplex 380. Now first off I had to take off the guard that is around the vga, hdmi and the other port for the card to fit. Once I changed out the e8500 to the e8500 I booted it up to see if it worked(without gpu in the pc). Worked just fine. Then I turned it off and put the gpu in, I connected the vga cable to the gpu and when I turned the pc on, no signal, so I then plugged it into on board, no signal, I also noticed something the fans rims stayed at one pace (normally they very at startup). I don't think the pc was going through post. I then did some research online and saw that the psu was 230w, so I grabbed an old inspiron psu that I used to have a gtx 750 ti and an it running off of,.and I put it into the optiplex, same problem. Then I reset cmos, same problem. Then I went into bios and changed it from auto to PED. Same problem. I have no idea what to do next. (tested gpu in my regular pc and it works fine).
