Finally my first build for myself (I've built for a friend and gave a parts list to another). Anyways my new build was having so many problems. First it wasn't doing anything at all when I tried to turn it on. Then I found out the motherboard kept getting grounded out. So I rescrewed in the motherboard, and was getting some life. It would then turn on for like half a second then turn off. Then I found out it was still being ground out so I took out about half the screws and loosenedthe rest in there. Now it was staying on for a couple minutes, but was overheating.

I applied new thermal paste (small amount, evenly spread) and put my thermaltake heatsink on. I hooked it all up and the bios was saying my processor temperature was going up like 2 degrees celsius every second and it went pass 100 celsius and I just turned it off. I cleaned the processor/heatsink, put new thermal paste on and put the heatsink back on. It seemed to be working fine now. So I decide to hook the screen up and its no longer giving me video! This is making me go nuts! So I try some different things and nothing. I try putting my motherboard back in again, and it kept grounding out unless I only have like 5 screws in very loose.

So my problem now is I get no display. I think this case (apevia X-cruiser) keeps grounding out my motherboard (XFX nvidia 650i)

I know the processor and power supply work. I think its still grounding out. It's doing the thing where it flickers on then right off in less then a second. I really appreciate any help, I'm getting very frustrated and have spent over 10 hours just trying to get this to work.

With the mobo out, look where the board mounts. Sometimes there's a protrusion in the metal that might contact the mobo. They sell insulated washers or you can make some out of thin rubber, for the stand-offs or even place electrical tape over the stand-offs and poke a hole through it for the screws. Tighten up the mounting screws. You want it firmly mounted. The mobo needs to be grounded but in the right places. Make sure the video card is mounted firmly and don't forget the extra power connector

This is really weird. Things just got worse.... All it does now is the light will turn on the motherboard when I press the on button. Another green light will flash on and thats it. The orange light stays on, but pressing the button again does nothing. I have to flip the power switch on the psu to get it to let me press the on button again to get it just to flash the light on the motherboard... Man I'm the unluckiest person ever :thumbsup:

I'll try what you told me Garmanma. I'm getting tired now. I've been working on this thing since 3:00 P.M. today and a lot of yesterday. I've made less progress.

Well I've come to the conclusion that this board is just dead. I had my thoughts about it from the reviews, and also a lot of the capicitors were bent a little.

Also, last night the battery sparked on me just by pressing the power button the case, and I could smell burning. I tried the board outside of the case in a box and its giving me the same problem where it turns on foir like half a second and automatically shuts off...

lol, this board might be staying in this box and taking a long trip to california.

you have doublechecked all your standoffs? those are the posts screwed into the backplate that the motherboard mounts to?

the motherboard is grounded by those screws and posts, see the little ring of silver around each hole

double check all your case wiring for continuity or shorts, cheap cases come with shorts on the usb whatever?

xfx or thermaltake is a good brand, apeiva is not

I often check a motherboard in a bench test on a bubbled plastic layer before putting in the case if I suspect issues

you just need cpu/cooler ram and video and powersupply and keyboard

a small screw driver shorting the power on leads for a second will turn the setup on

if I am using a refurb or rma openbox mobo I always clear cmos and do this benchtest

No. Try not. Do... or do not. There is no try.
