Troubleshootin a dead system
Posted on 2007-11-23
I upgraded two of my computers lately.
Nearly everything is the same:
Both: Intel Core 2 Duo E4400 Allendale 2.0GHz
Both: Seagate Barracuda 7200 320GB SATA
Both: 2GB memory
System #1: External video adapter, GEForce 7300
System #1: Intel BOXDP965LTCK LGA 775 Intel P96 system board
System #2: MSI 945GM3-F system board
I had both working fine. I recently installed some software and on the reboot, system #1 would not boot up.
So, I swapped the memory with the working system, #2. It works fine.
I placed the processor in system #2, and it works fine.
I placed the external video in system #2 and it works fine.
So, I determined it must be the system board. I sent off for a replacement rma, and have just installed it, and still experience the same symptoms!
I even tried the hard drive in the working computer and let it boot up to the XP splash screen before powering down.
I turn it on, and all fans run. It also sounds like the hard drive is spinning up, lights look normal, but I never get a video signal, nor do I get any POST beeps from the internal speaker.
What could I be missing? The only thing I have not tried, is the power supply from the working system, but it is getting power, obviously, so should I even bother?
