|I am Troubleshooting an Inspiorn 580 desktop for a client. They told me before they called me, they spoke with Dell and reported 4 beeps. Dell is telling them it is a memory failure.|
Along I come, I plug in their CPU, and there are NO beeps at all. Not even the general POST single beep, and no video. I removed all memory modules and power it back on and get two beeps (again, no video), which according to AMIBIOS is a parity error, and recommends memory replacement. I put in each module, one by one, into slot 1 to see if it will boot or even POST, but non of the three modules will boot the PC and don't even present any beeps and still no video.
I also unplugged all peripherals and, fans, etc. (just keeping the hard drive powered), to ensure the power supply wasn't being over loaded, and continued to test each module in slot 1 again, but still nothing at all. I can hear the hard drive spin up, and there is an amber light on the motherboard and a green light on the power supply. Only devices plugged in are keyboard, monitor and power cord. And I have cleared the BIOS as well.
At this point, I am leaning towards this being a motherboard issue. Anyone have any thoughts on what it might be or anything I could have overlooked?
