I put a thread in recently about how to test a new Motherboard before installation and followed the advice received. The board was DOA and I returned the board by Express Post (overnight) as a warranty claim. Under that obligation, I pay the freight (it cost us $12) to the on-line store and they ship me a new board for free.
Firstly though, they of course test the board to see if it is really dead.
Guess what?
After following the advice kindly given in my 'How to test a new motherboard before installation' thread and finding the board DOA, I shipped the board back to the on-line store and they tell me their 'Tech. Department'' (ho, ho, we are talking about VERY small stores here in OZ and some of them probably operating out of their garage), say there is nothing wrong with the board …and that it will cost me $45 for the testing plus $18 postage to send the board back to me (this is a $100 Gigabyte GA-45T-UD3LRT 775 socket, DDR3 board).
"OK, so were did I go wrong in the testing?" I ask.
Well there might have been something faulty somewhere with you testing equipment" they say.
'Well, I used a Corsair 520w ATX PSU (checked with a multi-meter), a brand new E7300 core duo plus it's heatsink, 1 stick of Corsair ram from a 2x kit that I KNOW is good (tried both sticks), an added fan hand-held and 2 different boot-up buttons tried that I know work, a small speaker and my own PC display, so please tell me how the motherboard is possibly a good one. Not even the fans spun up!"

"Well, you will have to ship us all your testing equipment so we can find out what is wrong with it and that will be another $45 labor to do that and the return (huge) freight cost." Oh sure, I'm going to pay for the cost of all that freight both ways and do without my display until it all comes back at my expense, For a $100 board?

And then ..and THEN .. they gave themselves away (I think) ! They told me they ":upgraded the 'board's firmware …that's Bios to you".
Hello, hello? Upgraded the 'motherboard' bios (?) on a motherboard test bench, without a HD and OS?

That is a

isn't it?
Actually, I think it can be done using DOS and a floppy and the right downloads from the motherboard manufacturer etc
with access to the Internet from another PC to make up a specific diskette, but why in the hell would a shop bother?
Updating the bios, for what purpose? To 'fix' the motherboard?
I said to them that they have just replaced the motherboard, charged me $63 total to get a working board. They then will of course, make a warranty claim for the dud board with Gigabyte! "Oh no they say, you can check the serial number of the returned board which is on your original invoice"!
Now that stumped me. Is the serial number on these boards stamped or on a sticker? If its on a sticker, then they don't print a sticker for every board they make, It must just be a batch or model serial number (?). If the boards are individually stamped, did they fix the board somehow ( a well known minor fault easily fixed or something, or were they right, my testing set-up was wrong or faulty)?
Could a faulty new CPU be the culprit? Wouldn't the fans at least spin, and don't you get a beep from the speaker if the CPU is Faulty?
I'm building this PC for someone, with their money not mine, so the situation really bothers me.
