No signal/Processor not working?

[llamapoo]

A friend is having a problem with a new computer he bought and is now putting together. The parts are:

G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
Antec EarthWatts EA650 650W Continuous Power ATX12V Ver.2.2 / EPS12V version 2.91 SLI Certified CrossFire Ready
MSI 790GX-G65 AM3 AMD 790GX HDMI ATX AMD Motherboard - Retail
AMD Phenom II X4 965 Black Edition Deneb 3.4GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM3 140W Quad-Core Processor
SAPPHIRE Vapor-X Radeon HD 4870 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card

He's gotten everything connected right, I've had him check, but when he turns it on the monitor gets a signal but says it's not showing anything. It goes from no signal to I guess standby would be the term.

He says he's left it on for a couple minutes and the processor was still cold, could it mean the processor is DOA or is there a smaller problem with something?

I've read another forum where a couple people are having the same problem and they believe it to be the motherboard he bought, any ideas on that?

the best thing you can do is test the cpu on a different motherboard (if available!).
cpu is cold = means it isnt getting power! make sure you connected the cpu power adapter (4pin or 8pin).

oh and do you have the little speaker(beeper) on the motherboard? sometimes its on the motherboard, sometimes its portable so you can plug it off if you want. if its not on the motherboard then plug it in and see if it makes any beeps!

After reading some more it seems it's a hit or miss motherboard with more misses than hits, so he went ahead and got a new mobo, we shall see monday!

Sounds like a classic #2 on the checklist.
