Hi, i'm new to this place and it's unfortunate that i had to come across this place in a time of need. My computer i put together about a year and a half ago all of a sudden gave me a suprise problem today after it worked fine the night before when i shut it down (properly i might ad). To start things off, I have a P4S800D MoBo i bought off of newegg a year and a half ago (June 2004). Currently I have.. P4 2.8 HT 1.5 Gig RAM PC 2700 2 hardrives ( a 40 gig the operating system is on and a 160 secondary drive) cd-writer dvd burner Antec 430w PSU Nvidia 6800gt Windows XP Pro Now my computer has ran fine up until last night.....the only exception is that starting over the summer of 05, i noticed occasionally when i turn the system on or restart it, it'd show the "P4S800D" screen then before it'd boot up the operating system, it'd just get stuck at a black screen....this is solved just by me hitting the reset button on the tower and then it boots fine. Well, today i go to turn the tower on. I hit the on button, everything lights up, all the fans turn on, the video card turns on but the monitor displays a "no signal self test performed video cable and monitor ok check your PC". This normally would sound like a video card issue but i noticed that the system itself isn't booting into the operating system. I can tell this because strangely, the cd-rom light is staying on, and i can't open or close the drive itself. Also, normally when i first turn the system on, even when i restart it, the system usually makes a quick, short beep. This time there isn't a beep. So far to fix this problem i've... un-plugged the cd drives unplugged my secondary drive unplugged the video card and re-installed it back it to make sure it was secure un latched my cpu/heatsink and relatched it cleared the CMOS tommorow i'm going to try taking the board out and putting it on cardboard to see if it'll boot from there, but if it doesn't, what could be the issue? I'm hoping it's not the processor, because i can replace the board for 50 bucks but what physical signs should i look for to tell if it's not the processor? Also, is there still a possibility i can get a exchanged board from ASUS still even though my board is over a year and a half from when i first purchased?
