Okay, so I recently purchased parts to build a new computer. After putting it all together, I plug it in and turn it on. It seems to be working well for the 5-7 seconds that it's on, before it shuts down. I've already taken it apart and putting it back together at least five times.
The specifications are as follows:
Asus Sabertooth 990FX R2.0 AM3+ Motherboard
AMD FX-9370 Eight-Core 4.7Ghz
Kingwin Maximum Power Supply 750 Watts
WD BLACK 1 TB SATA 6 GB/S 3.5"
MSI AMD RADEON R9 280X GAMING 6GB GDDR5
CORSAIR HYDRO SERIESTM H75 LIQUID CPU COOLER
16gb Corsair Vengeance 1866hz ram

Please help me... you're my only hope.


Okay, so I got the computer to send a signal to my monitor. It turned on for about 15-20 seconds that time, but in the end, shut down again. I haven't had a chance to install windows on it yet due to this persisting problem.

"Kingwin Maximum Power Supply 750 Watts"...shudders

I can't stress enough the importance of a high quality PSU. If you have the option of returning that PSU and getting a quality unit you will thank be later.

Anyway, we have a troubleshooting sticky with a checklist for this type of problem. Perform all the steps in the checklist and let us know how it goes. There's also a link to the checklist in my signature.

The new Kingwin Lazer units are good (built by Superflower), but if that's an old, non-80+ unit, it is probably near junk.
Monitor your temps in the BIOS. If your CPU or mobo temps are rapidly climbing, your HSF may not be securely in place. Reset the BIOS to defaults to make sure there isn't an overclock applied.

I've already looked though the troubleshooting sticky before trying this and tried all of the steps. So you think the psu may be the issue?

Make sure you have a BIOS revision that supports your CPU.

I don't think it's a BIOS problem. I'm new to pc building (this is the first time I've built one). I ordered some of the parts as a bundle on Tigerdirect, so there shouldn't be a compatibility issue, should there? (the cpu and motherboard were included in the combo).

1) Is the PSU 80+ certified, or does it have a little voltage switch on it?
2) Being in a bundle is no guarantee of compatibility. In fact, Newegg's bundles specifically state there is no such guarantee. I would expect TigerDirect to be similar.

Thanks for trying to help everyone. The problem has been fixed. It turns out that the pump to my liquid cooler was plugged into the wrong port. All is running well. In fact, I'm posting this on my new pc. Thanks again!!!
