I thought you could get into the BIOS. What changed??
If it was after the PSU change, try putting the original PSU back in.
"Well if it helps...I just tried to turn it on and I've got nothing now but a fan that is spinning really fast. The little blue power light isn't even coming on now... SO, is that a helpful indicator of what the problem could be? "
I don't know what has changed in the past two weeks or so, but now this happens. everything in the system is original and from the manufacturer. I took the PSU back since that did not help the situation. No need to buy what I don't need. I'm planning on building a new computer sometime this year, so if it is my HD that's fine, I can reuse it later.
