I heard you guys can help?

After building my first PC (feeling rather proud and anxious), I come across a problem. It turns off after 2 short seconds. Great.

I tried unplugging all fans in case my power supply couldn't supply enough power to the mobo, no luck.

I tried putting back on the CPU fan in case the water cooling was causing problems, no luck.

I tried replacing the power supply (with what I had: a 300w), and the same problem occurred. Everything would still turn off after 2 seconds.

My only thought to this is perhaps my wires are on backwards? For the power, reset buttons etc. The manuals did tell me where they went, just not which colors hit which pin, and how I can tell if I have it on right or not.

Anyone have suggestions? I really have no idea what the problem could be.

Unfortunately I did not do a post test. I didn't know about it until I finished building my PC.

Some potentially concerned parts:
ASUS P8P67 LE Motherboard
Intel® Core™ i5-2500K Processor
CORSAIR 800w Power supply

Thanks,
Marc

Are all power connectors in all the way? Is the RAM pushed in all the way? Are you sure you installed all of the motherboard standoffs?

All the connectors seem to be properly connected. Although my power supply doesn't have the 8-pin connector for the CPU power supply...(?)

RAM is properly inserted and I haven't even installed anything yet. This is my first boot, and doesn't get further than 2 seconds of starting. I haven't even bothered plugging my mouse/keyboard or monitor.

Thanks for the quick replies smile.gif

Mind taking a pic so we can see what's connected to what.
Are you sure that everything is plugged in correctly?

This was it, I never found that wire until now. I had it shoved in the backing of my case. And knowing now there's only one of those, it was easy for my eye to miss it.

I feel stupid, just relieved that's over with.

Now, I just have to deal with this long, then 2 short beeps looping -_-
Fixed after google'ing Asus beeping codes.

My current issue right now is that my monitor goes power saving mode even though it's plugged in my motherboard(?).

Help? frown.gif

Help?

Do you have a graphics card? If yes, check if it has PCI-E power plugs. you need to plug it(them) in and connect the monitor cable

I tried it with my motherboard. I assumed I had everything plugged and powered(?).

I also tried it with my own video card and still nothing. It is a radeon HD 6450 sapphire. I do not see any PCI-E power plugs and I had this card used on a previous computer recently - no problems encountered.

Your motherboard chipset does not support onboard video. Check that the monitor is plugged into the graphics card and NOT the motherboard, that the card is seated properly, and that all power connectors on it are plugged in and secure (if it needs any, they may be on the side or back, or it may not have any). If none of this works try another video card. Good luck!

i made the same mistake.

Make sure the 8 pin power cable to the Top Left hand corner of your mobo is TIGHTLY in place, or it will not boot tongue.gif, none the less power up.

i mean, the first time i plugged it in there, i thought it was in, then i tried doing Mem-ok which allowed the PC to have power, but do nothing else. Then when i plugged that in tighter, it worked! thumb.gif

also make sure on the back of the power supply is set to 120v not 240.
