Hello I am having serious issues with my desktop. A while back I bought a new R9-270 graphics card and when it arrived it would not work in my computer all the fans and lights came on but no post. So I tried a new PSU that I know is good and still nothing. Eventually I just put the R9 in my fiance's computer and took her R7-260x and everything worked fine for a while. After a few weeks the video card stopped working so I put it in the other pci slot on my mobo and it worked fine again so i just figured the slot burned out or something. So about two weeks ago I ordered a new mobo to replace the aging one which is about 3 years old now. I put the R9 in with the new mobo and everything worked just fine for 2 days then the same problem with it not posting happened again. So then I put the old mobo back in with the R7 and it worked for a week now the old mobo and R7 wont post. So I have even tried putting in a small old v-card, took out the v-card, took out all but one ram stick and alternated them, took out all ram sticks. All with no luck at all. Even with no v-card or ram still no post and no beeps. I dont know what to do.
