Looks like the mtrbd. is shot, though with no video it could be a video problem. Are there any beeps, during boot-up? You don't need any HD/CD drives attached, try to boot, results? Swap ram around or try known good ones. Any burnt smells, cabling OK, beeps? Did you return bios jumper to proper setting as to not "clear setting". Have you tried a another video card. What was the system before this problem cropped-up? Any recent install or action before this happened. Any power surges, lightening strikes, hot room, etc.?
You can remove the system mtrbd..etc. to a cardboard on table, attach a minimum system and try boot-up and/or retry above actions.
This computer has no video,keyboard,sound or mouse functions. SATA Hatachi Travelstar 500 gb hdd spins up,ethernet lite is lit,psu & power button are lit as well. dvd/rw drive opens & closes at my command. CPU HSF spins up fast for a second then slows down a bit but continues to spin at a slow rate like it a normal function. Tried resetting bios by removing the cmos batt & moving jumper. Thinking of purchasing a pci 4 digit readout diognotic post card & installing it in the pci slot. Took the hdd out * installed it in my running pc & it recoginizes it. Has Windows Vista Home Premium 64 bit installed. What other testing do i need to perform? Also was planning on purchasing a programmed bios chip & installing it to see if it might be a bios failure issue. Any ideas would be greatful. Thanks! David
