I went to turn on my computer on day and the monitor gave the message of no video. I thought it was either a bad video card or a bad slot on the mother board. I first replaced the video and still had nothing. I then proceded to replace the mother board and still nothing. I thought it could be a flakey psu so I replaced it. Still nothing.I also tried the monitor on my laptop and the monitor works. The only thought I have left is the memory. Is there any way that the psu could have fried both the old and new parts before I changed out the psu? or is there another posibility?
