ok i tore my computer down to clean out some dust and re-route some cables for a cleaner look and better air flow. i also cut out some grates over the fans on the case for better air flow. i tore everything apart down to the bare chassis. kept everything organized and handled everything carefully. this isnt my first time inside a computer case. so i put everything back together fired it up and nothing. nothing on the screen, no post, nothing. system: asus p4g8x delux MB p4 2.4 GHz PATA 320 GB SATA 500GB PATA dvd r/rw 1 GB ram symptoms upon power up: all fans come on (case, cpu, psu) green light on MB is on DVD drive works (tray opens and spins a disc if its in there) HDD light is on all the time both HDDs spin up no display no beeps things ive tried unsuccessfully: different video card no video card no HDD or DVD drive hooked up no front panel connectors connected hooked up (besides power switch) 12V cpu connector removed and EZ-connector hooked up (and vice cersa) combinations of the above the system worked beautifully before. i dont see any reason why it shouldnt boot now. anyone have any ideas?
