If the CPU is dead ... ? (help diagnose)
...will anything on the motherboard ( any fans ) spin? I've tried 2 different power supplies, 2 different video cards, 3 different sticks of ram, all known good components. ...all done while it's outside of the case sitting on the antistat bag. There's no p.o.s.t. beep and no beep codes happening. The fans don't even do that little 1 second jerk that sometimes happens. CMOS has been reset with the jumper. The last symptom that I saw was that the power light on the front of the case was blinking but nothing spins. I'm hoping not to have to test this CPU in my other ( exactly the same ) motherboard. Any thoughts? Thanks,

Just a thought, did you put the CMOS jumper back to it's normal position?

Hi Steve,
FWIW, Out of literally hundreds of DAWs that I've built over the past ~15 years, I've only seen a single CPU go bad.
I'd put my money on the motherboard being bad...

Hi Jim, Yes. From the behavior right before it totally stopped responding that's my quess also. It's under warranty and there's no hurry so I'll just send it back. Thanks for the input. Much appreciated.

I've already tried 2 known good PS. Thanks,

sorry steve, didn't read that the first time around. it's almost certainly the motherboard. if you haven't replaced the battery on it you might try that. usually though, a dead battery will still allow boot from time to time.

Oh ... no problem. Yes I did replace the battery about 3 weeks ago. It did boot fine then with the dead battery, but just wouldn't hold any settings in the bios if shut down. I do appreciate all of you thoughts. Thank you!

I no on my MSI MB if I don't have a fan plugged into a certain ps jumper the board won't start.
It's a way of preventing you from frying the CPU
Even if the CPU was fried you would still get some sort of power indication.
I'd start at the begining of the chain (power supply) and work one step at a time

...will anything on the motherboard ( any fans ) spin?
I've tried 2 different power supplies, 2 different video cards, 3 different sticks of ram,
all known good components.
...all done while it's outside of the case sitting on the antistat bag.
There's no p.o.s.t. beep and no beep codes happening.
The fans don't even do that little 1 second jerk that sometimes happens.
CMOS has been reset with the jumper.
The last symptom that I saw was that the power light on the front of the case
was blinking but nothing spins.
I'm hoping not to have to test this CPU in my other ( exactly the same ) motherboard.
Any thoughts? Thanks,
it *might* differ from board to board but I'm pretty sure the fans will spin no matter what, 'cos the CMOS will see to that. However, I think that's about all that'll happen. I once had a cpu go tits up and the board would still post, only just and only once the board had been not powered up for a while. Probably the cheapest/easiest way to test is to by a pc-chips el-cheapo motherboard to test your chip. Kind regards Dave Rich

Hi Dave,
yep. That was my suspicion also ... that there should at least be some indication of activity even if it's just the power supply
fan.
I'm sending it back to MSI in a few days.

atx boards have "soft" power switches so if you get nothing at all then it's either the psu or the mobo, since you've already swapped the psu...

We have 15 computers at work that I help maintain. Two of them were built for 2 different employees to use from their home. Both were built after the others and have MSI motherboards. The day after Christmas both MSI mobo computers were dragged into work with the same symptoms of yours and these 2 people don't live together, same house or anything. After scratching my head calculating the odds of that happening I started swapping parts.
We have new power supplies in stock but they did no good. One powers up for random amounts of time then just shuts off. Even a boot to bios before hard disk activity it just shuts down. The other is just dead.
Outside of some bios virus or something I have no choice but to suspect the motherboard. In my almost 30 years of computing I have never seen a CPU go south... I know it happens but I think it's unlikely.
Let us know what you find and what motherboard you go with.

Thanks MWD.
That's a good thought about the bios chip, which happens to be user replacable on this board. Maybe I'll give that a try first since they're free for the asking ( MSI at least ) it seems.

a bios virus is a possible explanation but they are pretty rare. fortunately replacing the chip will fix the problem. =)

Well Steve it took a new motherboard to fix our first dead computer. Got an Asus with a dual core 3.0 ghz chip at Tiger pretty cheap.

I've got my RMA # and it's packed and ready to go back. Just gotta get to the post office. That seems to be the hardest part ... taking the time to go out of the house and be away from music work.
