I have a Dell Vostro 230 that will not boot. A while ago the system was running but very sluggish. It reported 1 GB of RAM but 2 GB were installed. I powered the system down to troubleshoot and now when I press the power button the processor and case cooling fans will briefly spin and then stop and then start again. The hard drives spins up and the DVD drive will spin if any media is in the drive. Unfortunately, that is where it ends. I have reseated all cables. I pulled each 1GB memory stick and swapped slots. I pulled memory from a working system and still nothing. If I try to boot with no memory, I get two beeps. I also swapped the hard drive with a working system and get nothing. No splash screen, no messages, nothing. Are there any troubleshooting steps I am missing?
