|Thanks folks. Much appreciated. Let me hit the high points.|
Firstly, ya'll are getting too strung up over the static bag. I'm aware what it is and what it will and won't do but thanks anyway. Long before I placed it on a static bag, I tried it in the case, then another case. Then pulled it and set it on my wooden desk. The problems existed before the static bag so let's put that to rest. I have not looked at this since my post but let me layout all other stuff I tried in detail as well as what I know to be fact. Maybe there was something obvious I don't see.
Original board is a Gigabyte with onboard and external video. Ran over ext vid and Celeron CPU fine but my son got older and then got into minecraft. Of course the Celeron is crap for such a thing so I bought a Core 2 Duo, DDR3 Memory (8GB)-- Lets not degrade the discussion into how a quad-core is better for gaming, etc... I require my boy to "earn" such things.-- and removed the Celeron and installed the Core2 Duo which he and I did together. His first PC upgrade at 9yrs old so I was expecting the chance that something gets broken. Put in the Core2 (working pull from a trustworthy seller) and immediately, the problem starts. No Post, No Beep (yes the speaker is hooked to the board), no video output. I assume he broke something during the pile-driver slips with the screwdriver a few times but let it run to see. After a few, you could hear it reboot and power up (no beeps) and repeat more and more frequently. Easy.. over-heating. Pull heatsink, put a MUCH bigger one on spec'd for quad-core, clean and add grease. Rebooting stops. Just runs and no video. Convinced we've killed the board, I remember my training and drop into hardware diagnosis mode.
I remove every component until all that is left is a mobo on my desk with a CPU, Heatsink, power wire from the case, ATX Power connector (left ATX 4 Pin unplugged). No external components, no extras of any kind. No memory either. Now before you start yelling that you can't boot a mobo without memory, let me assure you I know this. What you CAN do though is test the most basic functionality before hearing the beep that complains of no memory. This covers the PSU self-test. If it is good, the timer sends a reset to the CPU, the CPU executes the BIOS of the ROM and then starts executing the ROM BIOS which THEN starts looking for attached crap like video cards, on-board mem, etc. At least that's how I remember it but I may be a bit rusty. So at this point there is no reason I shouldn't get a beep unless my speaker is bad or it's not getting the reset to the CPU, right? Exactly what I thought. Let's eliminate the easy stuff first. I then pulled a speaker from another case and wired it to the board. Still no love. So this tells me, Power supply maybe. The timer chip is not getting a "good power' signal and never progresses beyond that. I plug in the 4pin. Still no love. I go get another power supply from the basement (I have way too many spare computers & parts), and plug it in. It's a Dell PSU of 300w. Smaller than my 450w but should be enough and has the 4pin connector. I get the same problem. No post, no beep, no video. Musta killed the mobo but one more test. Pull the Core2 and replace with the Celeron I just pulled. EXACT same problem. HAS TO BE the mobo. Order new mobo, repeat ALL above steps and EXACT same results like deja friggin' vu. Okay.. one more thing. I pull a Pentium4 from a running machine I test by powering on and booting up XP before pulling it. I put it in the brand new mobo and EXACT same problem. I've now tried, 3 CPUs, 2 MOBOs, 2 Speakers, 2 PSUs and a friggin' Partridge in a Pear Tree. What am I missing peeps? A little third-set-of-eyes is needed. Thanks for reading my novel.
