No POST trouble help

My PC will not boot. The monitor gets a display signal, however stays in sleep mode. I get no beeps during startup.

I have tried everything outlined in the tutorial I found here (except checking standoffs):

https://www.techspot.com/vb/topic53866.html

1. I swapped out memory for known good sticks.
2. Checked the hard drive in another machine.
3. Swapped a known good vid card.
4. Re-installed CPU.
5. Cleared CMOS.

FWIW, the mobo is an Asus P4P8400 SE.

Thanks,
Matt

Did it use to boot? If so, then it may be a faulty hardware component (likely Power Supply, even though it does turn on)

Otherwise you could BenchTest your PC

I do have another PSU I can try. Thanks for the bench test thread, I'll give that a try.

The machine is 4 years old, and yes, it booted fine up until now. BTW, I upgraded my memory a few months back, that is why I swapped known good memory as well.

ok therefore the parts are compatable

I'd say Power Supply Unit (PSU) as No. 1

I sure hope so! That would be the easiest and cheapest problem as of now. When I upgraded memory, I also added another hard drive. Maybe my PSU could not handle it?

No, the power for HDD is probably the same
But if you have installed extra Ram, that's extra power

Got it...thanks for the explanation.

It was not the PSU. I'll bench test it tonight as a last resort.

Bench test results.....mobo shot.

So looks like I'll be buying a new mobo, CPU, mem, vid card, and PSU.

Thanks for the update
I can't add anything, because I think you're right, it's Motherboard

Thanks for your help. I'll post a thread on which new components I'm considering.
