Ok, long story: About a month ago I had the idea of replacing the mobo inside of my Compaq Presario 6027US desktop, and I ordered it. I remove the current Intel mobo and Pentium 4 proc and replace it with a PC Chips mobo and AMD Athlon proc. It worked just fine. About a week ago, I discovered that the computer wouldn't boot correctly for some reason after I had properly shut it down the night before. Windows wouldn't reinstall, it would always get stuck at Installing Network. After a few days of trying some things I finally read on a forum to try disabling certain hardware in BIOS, so I disabled the network card. Windows installed (supposedly hooray, right?) and I thought that I finally had my computer back. Nope, somehow the integrated network card on the mobo had broken, so I decided to put everything back into the computer that was there when it was bought. Original Intel mobo and proc back in, everything plugged in. The power LED is red. Not a pretty sight, so I tried reseating all wires and proc, the LED is now green upon turning on the power. I'm so close I can feel it until...nothing shows up on the monitor. Nothing at all, not even BIOS. The monitor power light is orange meaning it has no signal I believe. So, hopefully after reading this epic tale you can help. I don't know what to fix or what to try, except that I tried putting in an AGP card thinking that maybe the integrated video card didn't work. No, that didn't work, either. Please, somebody help!
