hey there, I have an older Pentium 4 that I use as a secondary machine. I built it going on 10yrs ago and it has been a most reliable computer until recently. Few months ago I was getting the blue screen errors, which I pinpointed (or so I thought) to be my CPU, I replaced with a spare I had and the machine was back to normal, however I noticed that my 4GB dual channel ram was no reading as single channel. Because its a secondary machine I wasnt to concerned with this as the machine was atleast running. Last week I finally decided to pull all my sticks of ram out of the board in hopes it would reset everything and read dual channel, sadly this did not happen. My computer ended up not boting up at all, just a black screen.
I ended up going through each stick installing them one by one in each slot, and everytime the machine did not boot. I reset cmos using the jumper and pulling the battery and still had no success booting....While doing all this troubleshooting I had forgot that I had purposely unplugged the cases speaker. So I plugged the speaker back in and when the computer started I was getting very fast beeps.
I tested all hardware and it seems the beeping was related to the power supply. The beeping stopped whenever the 4-pin 12v connection was left unplugged. So I tested the connection with a multimeter and its reading 12.4v so the power supply doesnt seem to be the issue.
Soooo Is it my motherboard thats gone?? Im starting to think so......
Sorry to make my storry so long, but I wanted to cover every detail just so you can see what troubleshooting I have done. And its frustrating as I want to know / learn whats wrong.
