HELP new computer will not power on! - Page 2

post #11 of 31
If all else fails take everything out of the case and rebuild it on your motherboard box. Redo all the T/S steps with the hardware and swap in a spare PSU if you have access to one.

I checked all the connectors and everything is seated properly. I hope something is not defective, because everything is brand new. Then again this is my first build ever, so I dont really know much about this. I know I hooked up something right, being that it does power on for a split second and on the front of the case, the Blue LED turns on.

I will try and remove one of the ram sticks and pull out the GPU at the same time to see if that helps as someone suggested.

None of the case fans power on at all. The computer doesnt stay on long enough for that to even happen
It really sounds like a bad stick of ram or there is a short somewhere in your rig.

As stated above, unplug everything from the mobo except keyboard.

no mouse, monitor, video card, case fans. (leave your h50 pump only plugged in) Leave one stick of ram in the #1 slot. computer should post. Since the monitor is disconnected, you will only have the running pc to let you know it's ok.

Power off. Now add monitor to onboard graphics plug. Restart. If it posts to bios screen, your on your way.

Shut down and now add mouse, restart... It's annoying but it's the only to isolate your problem.

If the barebones start up listed above doesnt post, remove the one stick of ram and try another stick,

Good luck.

Another thing, you did mount the post standoffs for your mobo right? as mentioned above, be sure your mobo is mounted floating in your case.

I googled this problem just now, and found out that it could be a faulty psu, or a short in the system, but I didnt find any other possibilities.

I found this article here with another person why had EXACTLY dead on the same problem I currently do http://www.tomshardware.com/forum/30...ns-split-shuts

His problem was a faulty psu even though it was new like mine is. The second article stated it was also a faulty psu.

Here is my video, so you guys know what im talking about:
I think what im gona do, is test my psu from my current computer to see if it will work in the new build.

Using the PSU in another rig is a good idea, just be wary if it is faulty it may cause damage to your good rig. I would suggest using the known good PSU on the new build instead. That is the safest way to rule a faulty PSU, assuming it hasn't already damaged your new rig!

Not that it will solve this particular issue, but for future builds, get a case speaker. They are like 5 bucks and can save you hours of head scratching/keep your blood pressure down!

By the way, I recommended that you check your RAM because I have had 2 build where a faulty RAM stick prevented the rig from posting, was just an idea! Looks like you have it narrowed down to the PSU or a shunt/short though. Good luck man!

update! I swap the psu from my old computer and it still doesnt work. I even install my new antec psu into my old computer and everything worked fine. so the psu was fine. It turned out that the screws for the motherboard were a tad too tight? they didnt feel that tight but, i loosened them up a LOT and now it boots up. Another problem... now its cycling

It will stay on for a little while and then it will turn off by itself, and then turn itself back on after a few seconds, what does that mean? I havent hooked everything up yet

install the ram, vga, keyboard. the bare minimum to post. if that doesnt work try resetting the cmos. unplug everything first and then pull the cmos battery out and let it sit for a bit.

i know you said you followed instructions precisely, but double check your cpu. remove it from the socket (make sure you ground yourself) check the mobo cpu socket for bent pins. also make sure the triangle on the cpu lines up with the triangle on the socket(common mistake).

hmmm, u say you loosened the mobo screws and now it posts but cycles... thats scary. U may have shorted something on the back of your board. U may have to remove the mobo and inspect the underside of it for any burns.

I see u still had 2 sticks of ram in, remove 1.

Your grounding out the mobo, or hopefully not, killed your bios chip. Do you have an LCD poster on your board? Like someone else said, pull the mobo out of the case. And do a bare bones setup on a cardboard box, that would take a shorting out on the case away. Also are you using all the standoffs needed?
