Hi, I just built a brand new computer. Right now I have CPU, Vid card, ram, and power supply in. When I turn it on, it goes off one second later. The LED light on the mobo goes out, so theres no power. 30 seconds later, I can try the same thing but I get the same result.

My system:
C2D 4400
8800gt
OCZ 1x1gb Ram
Earthwatt 500w PS

I heared that my ram needs 2.1v so that could be a problem. If it was the ram, wouldn't the power still be on the mobo? So right now im stump on what it could be. Maybe weak PS? Or Vid card. Right now I dont have any spare parts to test. Anyone help?
 
Ok, its turning on now, but no video. Could it be the vid card or ram?
 
I'm pretty sure it's your ram. OCZ are far tooooo popular for not letting the ip35s even get to BIOS so that you can bump up the vdimm.
I would find someone with one stick of any ddr2 ram that you can use for half a day. Plug it in, get in BIOS, up the vdimm, and away you go. But, there will be another time you need different ram again if you plan on OCing.
chances of problem being ram 98%
earthwatts 1%
video card .5%
mobo .5%
 
I would try testing the power supply since the motherboard power light is out. If the power supply tests good then I would start looking at motherboard or ram.
 
Ok, I tried swapping the ram out, and I tried the other OCZ ram. Got the same thing, boots up but no video. I messed around with it some more, changing slots, resetting cmos, now it doesn't boot up. The mobo LED is on but It doesn't boot up :(.
 
It turns out one of my power pins was loose. Its booting up now but still no video showing. I'm thinking its either the ram or vid card.
 
I will try to get some other brand of Ram and test

Thund3rb1rd, I do plan to OC, why would I need some other ram again?

Thanks.
 
because when if you ever flash you bios to either 12 or 14, which is more than likely, you will have to reset cmos.
And that's if it goes 100% the first time, sometimes you have to reflash.
Or, there's always the chance for some other reason that you would need to reset cmos.

in any of these cases, the vdimm will drop back to 1.8v.
 
jesus go to manufacture web site and read up on possible bios updates and what they fix.do not flash just to flash have a viable reason or you may encounter a bad flash then you will be you the creek,unless your board has some sort of bios protection from a bad flash

Click to expand...

how many boards have you OCed on and didn't update the bios?
if the answer is 0 then STFU. If it's more than 0 name the board and tell us why, because more than likely it's because you're just to conservative to go as far as average to OC a chip.
