NO Signal to Monitor?! New PC, not booting up?! Ahh!!!!!!!!!

[Coldkilla]

The specs of the system:
Proc: Q6600
Mobo: LGA775 Intel P35
VC: 8800GTX e-Geforce 8800 eVGA
PSU: 600 Watt Seagate 12V Rails. Modular (My first Modular)



I turn my new computer on. The fans turn on, then less than a second later.. the PC shuts OFF. I hit the button again, then everything turns on. Sometimes the fan's don't all kick in at once though.. the computer can be on for nearly 5-8 seconds before the fans on certain compartments turn on.

No beeps are heard, nothing except a small hum that sounds in intervals comes from ether the motherboard or CPU.

I've tried:
1. The monitor displays a solid orange instead of green. I tried a CRT monitor, and it blinked green on and off.
2. Switched the new Modular 600Watt PSU with another 500Watt PSU (NOT modular)
3. Switched the new PCI Express 8800GTX with another PCi Express 7900GTX
4. Switched the new empty HDD with my old XP drive still loaded with data and OS
5. Unplugged the DVD Drive(s).

I don't know what it is!! Any help appreciated! Thanks.

Nevertheless, from the LED state I would guess it is not getting a signal. The fact that the fans are running means power is getting to them, but it doesn't mean the machine is booting, and it sounds like yours isn't.

Are you getting any beep codes at power-on or right after?

I changed my main post with more information to perhaps help in the upcoming replys. I answered your question in the main post now Markbnj.

There is no 'beep codes' at startup. Just a quiet: hum *break* hum *break* coming from the motherboard or CPU, not sure which. Its quiet to the point where once the fans speed up, its not able to be heard. Perhaps this is just how the system works as I've not built a PC in manys months/year.

Also to note: The PC never starts the first time I hit the power button. It has to be hit again. Also, sometimes when it does stay on for 5 seconds after I hit the power button, it shuts off. Nothing physically is moving inside the case... and when it stays on for about 5-10 seconds, it stays on forever.

Up!!!!!!!!!!!!!!!!!!!!!!!!!!

You did try switching around different sticks of ram right? Have you doublechecked everything is hooked up right between the case/chassis and the mobo? If all are true, then it sounds like a DOA motherboard. RMA time.

You should start unplugging unnecessary peripheral cards and then move onto the somewhat necessary items (memory, video card, etc) until you can get it to POST. If it doesn't post, it's much more likely to be a motherboard issue as CPU issues are a bit less common.

I had a similar situation awhile ago with my old Athlon 64 X2 build. The BIOS needed to be updated to really support the X2, but until the BIOS was updated, I also couldn't use any peripheral (excluding video card) cards in the system or it refused to POST. Once I updated the BIOS, I plugged the cards in and all was fine. Quite weird of a situation.

I rewrote main post again. Hopefully I can make sure that this is the motherboards fault... I now have to postpone my FS thread on my current PC.

Could it be the case too? The "Power Switch" cord?

Also: Do I really need to REPAY shipping back to newegg for replacements? Thats nuts, for a case + motherboard!! It'll be 60 bucks to ship UPS or some crazy number... thats more than the cases worth!

Bump..... man I thought AT were the masters at this stuff

Anyways, I added my previous replies to the main post and tried to answer any question you guys have already had. There is no peripherals inside of the system at this time.

Looking for any help guys! I really need it. I'll be back in the morning! Looking forward to seething many responses!

To be honest, it's hard to diagnose a computer from possibly thousands of miles away, which is why the one thing I hate is people calling me up, "HALP! Computron broken!" I can't personally check things and have no way of redoing the work myself (some computer builds end up poor and I just pull everything out and redo it myself).

You probably have a DoA part or you didn't hook up all of the power cables to the motherboard (such as the 12V 4/8-pin connector).

The fact that you have to press the button twice is interesting. Did you try starting it by briefly shorting the two pins that the power button connects to? That will show whether it is the cord to the switch or not.

Looks like you've ruled out the PSU and peripherals. I didn't see where you changed out the RAM. That would be worth a shot. If you have multiple sticks get down to just one. If it still doesn't work I would be thinking a short, or a bad motherboard. Get everything out of the case and lay it out on a piece of cardboard, connect up just the basics and try it. If that still doesn't work RMA the mobo.

You should just remove the RAM and see if the machine POSTs. It won't really do anything other than beep, but it's part of the "Remove and check" procedure that I believe I talked about earlier. Essentially, you remove one piece (except CPU or HS/F obviously) and see if it POSTs. If not, try another (without putting the prior pieces back in) and see what happens. From what it sounds like, you only tried it with the peripheral cards and the drives.
