Hey everyone, I am sad to making my first post here under these circumstances. The problem: my desktop will not power on.

It happened randomly, shut it down when I went to sleep, wouldn't turn on in the morning. (now to be fair, I did a "hard" shutdown by holding the power button down).

Here is what I have ruled out so far. The problem cannot be:

The motherboard
The power supply

As for hard drives, you dont need them to turn on a computer, and I wouldn't think one would need a graphics card either, but my graphics card is 4 days old anyways, and it was workin perfect before this happened.

The reason I say it can't be the power supply or motherboard is because when I flip the switch on the PSU, the fan lights all over the case flash once like normal, and the network activity light beside my ethernet port (on the motherboard) turns on and flashes with network activity. This means that obviously power is getting through the supply to the mainboard and through the wires to other parts of the computer.

So, do you need RAM to turn on a computer? I have 0.00% clue but I would guess no, since the BIOS is on the motherboard? And do you need a processor? I would guess yes to that one...

Any thoughts? It is a custom built thing with no warranty of course. So if I can't solve this I'm just gonna make a new one and keep my old hard drives and brand new gfx card.

thx in advance for your thoughts :thumbsup:

No of course it's in there. Do you think that it died?

Power to the motherboard, power to the fans. It has to be the processor or the memory... right?

lol. no there's no beeps. no there's no video.

Imagine taking a staples "that was easy" button and removing the batteries. now press it.

as for the power supply switch, when it is turned from O to I (off to on) my custom case lights flash once, and the motherboard network activity light turns on and blinks with corresponding network activity (all desktops I've seen have this, the light by the ethernet port).


Processor eh?

Well, if it were me, I'd use a multimeter and check all the voltages on the plug to the motherboard. I don't know if that's an option for you. I'd also remove everything from the computer and run it on the workbench to make sure it isn't grounding out on the case somehow

The PSU can "partially" die, leaving only part of it providing power - so it still may be the PSU (but the likelihood decreases because it is putting out something).

As for the mobo, there's lot's of parts and traces all over the motherboard - the failure of one of them won't necessarily prevent the other parts of the mobo from working.

Does the hard drive spin up?

Most often (IME) these problems are associate with the RAM or the video (with the power supply and the mobo following close behind - I've seen very few failures of the processor). The issue here is that some of these things may not be needed to "boot" into the BIOS but damage to them can cause the computer not to boot into the BIOS. To add to the confusion, I've seen mobos that will boot without RAM and others that won't.

I'd suggest stripping the system down as far as you can - then try to boot and listen for beeps. Add a piece at a time while testing to see if you can determine what's causing it.

How bout trying your motherboard and PSU on another system? Yeah, that would involve dismantling the whole computer, but if it happens to me, I'd do that. I have way, way too much time in my hand :D

Good luck with the build. Only thing I would say is that an E6600 would have been better. If your going to have the best graphics why not have a decent cpu?

Wow ! I envy you, my system troubleshooting tools and knowledge, albeit limited does not allow me to whip out the debit card and conjure up a new system. But then, I am just jealous......lol

Just completed and set-up my first new build, I love it.

Word of advice, take your time, read and re-read installation guides. Avoid 'jumping the gun' just to see if it works.
Above all, if you should have questions or need assistance, by all means, make yourself a "pest" in the forums, it sure helped me out!

I've been to many forums, believe me, not 1 of them comes close the helpful and knowledgeable folks here !

Well the previous desktop only cost me 800 and that was 3 years ago. That's pretty good in my eyes.
This new one cost 1100 and I'm sure will last the same, cause when the insane dx10 games come out I can just throw in another 8800 GTS.

And this new one is gonna be much more top of the line than the old was when I bought it.

Btw what do yall recommend for OS? I heard Vista is retarted (in every way) and doesn't provide jack sh*t for the average user. I'm thinkin normal xp home or media center?

When is the first game or major app going to come out that ONLY works on vista or newer? Probably not too soon... and if soon, it's something I've most likely never heard of... right?

Oh and, do i need 2 of those ESD wrist straps, one for each hand? Cause no one is building a comp with just one hand lol...

If you live in an area where static electricity is high, you may want to go with 2 straps. It's cheap insurance, I had to discipline myself to just wear one. Here in Hawaii static electricity is not too bad, but I wore my strap anyway, I did not want my components to fry !
