MSI NEO2 PLATINUM PROBLEM

[RomanMtz]

Hello...

I was wondering if someone could help me with a problem I have with this new system I built. So I completed buying my parts for my new system and I put them all together. These parts included an OCZ Powerstrean 520W PSU, MSI NEO2 Plat mobo, 512 OCZ Plat. Rev 2 RAM and a new 3000+ socket 939 CPU.

My problem is that once I power the system on, it stays on for like 5 seconds (without showing a video signal) and then automatically shuts off. I tried different PSU's and RAM and the same thing happened. I'm thinking it's either the CPU or the mobo. Has this happened to anyone before? Please help me out here!

Thanks in advance!

Sounds like you have a couple of things going on with this new build. First and foremost, what do the diagnostic leds indicate? Second, have you tried a hard clearing of the cmos prior to firing the board up for the first time? Do you have the AUX 12v (square 4-pin cpu power conector) plugged into the board correctly? Made sure the ram and video card are seated properly?

Hey FastEddie, thanks for the reply...

I haven't had a chance to check the diagnostic leds thoroughly... I didn't pay much attention to this because the comp completely shuts off on its own after being on for about 4-5 seconds so I really can't distinguish where the leds were when it shuts off...

I cleared the CMOS before firing the system up for the first time and then again when it didn't turn on the first time and it did nothing to the problem. I do have both power supply plugs plugged in correctly to the mobo and the vid card and RAM seated right...

I was wondering if anyone had a similar problem and what they did to solve it... anyone?

That's a little more info. Try taking the board out of the case and try getting it fired up. Sounds like you have a short from the board to the case. Any standoffs you may have missed when installing the board in the case? Also take a look at the I/O shield on the back and make sure none of the grounding tabs are jammed into either the onboard usb or ps2 connectors. And if you have any front panel usb or sound connected, disconnect from the motherboard.

Another item to take a close look at is the floppy power connector--should just remove that connector and cabling from the drive until you get the board fired up.

I'm gonna try taking it out of the case... I dont think anything is shorted though.
