Today I put my old PS into this computer. The stock one on this machine was a 250w the one I put in it is a 300w & I know it works. And when I booted it the monitor immediately went to sleep saying there is no video signal. As I was writing this I realized that I didn't check the cable connection at the monitor, I just did & it appears to be ok. On the other end I tried it with the monitor cable connected to both the new video card & the onboard card with the same results. I don't want to plant evil thoughts, but I'm wondering about motherboard or virus or maybe hd??? On second thought if it was hd there still should be a video signal...could it be the new video card went bad so quickly? Sounds too coincidental to me...
Right now I'm having amnesia and deja vu at the same time. I think I've forgotten this before.
