OK, I just received my MSI K9N SLI Platinum motherboard and AMD Athlon 64 3500+ processor. I installed them in my Antec Sonata II case along with hard drive, cd-rom, video card, and floppy drive. The RAM hadn't come yet. Then for some unknown reason, I decided to turned it on to see if it would go into the bios so I could check the processor for DOA. Zipzoomfly.com only has a 15 day return policy on processors and my ram was on backorder.

I turned it on and I get lights and it seemed to be running, but nothing was displayed on the screen. So I look at the motherboard and the 4-pin CPU power connector wasn't connected. I plug it in....ZAP! Turns out the power was still on...I know I'm a dumb ass.

I turned it back off and plugged in the 4-pin connector and turned it back on. The power stays on for less than a second, the fans jump and the light goes on and then goes off, I hear capacitors start to charge and then stop. I disconnected the 4-pin connector, and all is well, fans spin, hard drive wrrrrrrrs, capacitors charging.

I removed the processor. It doesn't look scorched or fried or anything. I kept the 4-pin connector plugged in and same thing, starts then immediately stops. Disconnect 4-pin connector, all is well.

Before I go crazy and start spending a crap load more money, what should I replace? If anything. Because there isn't any RAM, would this problem have happened even if the connector had been properly plugged in, system starts then immediately turn off? Should I attempt to install the RAM when it gets here or will it be fried?

Could it possibly be the power supply was fried? or just the motherboard? or the CPU? or all 3?

Any help is appreciated. I've done countless searches on the internet for help, but I decided to post instead. Hopefully when I RMA they won't find out I was a dumb ass and will send me a new product.

Thank you,
Kyle.

Your board isn't going to work without RAM.

It doesn't sound like it's damaged but I would memtest it for 8-12 hours and run prime95 to make sure.

Unzip memtest86 and record the ISO to a CDR with ISORecorder ( you must have XP SP2 ).

Also you could try running Knoppix and see if you have any stability issues.
