Socket AM2 64 x2 4600+ system WILL NOT POST

[Pungolo_Fiero]

Alright here is the backstory - a few weeks ago I built the following
system from scratch with parts ordered from Newegg:

AMD Athlon 64 X2 4600+ Windsor 2.4GHz Socket AM2 Dual Core Processor
Model ADA4600CUBOX
ASUS EN7600GT SILENT/2DHT/256M Geforce 7600GT 256MB
GDDR3 PCI Express x16 Video Card
ABIT KN9S Socket AM2 NVIDIA nForce 550 MCP ATX AMD Motherboard
[b:1fb3adad01]pqi TURBO 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2
6400) Unbuffered Dual Channel Kit[/b:1fb3adad01]
Western Digital Caviar SE16 WD2500KS 250GB 7200 RPM SATA 3.0Gb/s Hard
Drive
[b:1fb3adad01]XCLIO GOODPOWER 500W ATX 500W Power
Supply[/b:1fb3adad01]
ASUS Silver ATAPI/E-IDE DVD-ROM Drive Model DVD-E616A2 SV
[b:1fb3adad01]NEC 16X DVD±R DVD Burner Silver IDE/ATAPI Model ND-3550A
- OEM[/b:1fb3adad01]
Viewsonic VA902b LCD 19'' Analog Monitor

The first time I tried to boot the system I got power to the fans and
LEDs but no signs of actual system life (aka no POST beeps, no BIOS,
ect...). A week later I RMA'd the CPU thinking that was my problem.
I have since received a brand new CPU and still have the same issues.
My fans run, the LEDs on the MoBo and case light up, and the drives
can open and everything. All I can think of is that my motherboard
is possibly faulty. Any help would be greatly appreciated. I've
been without a PC for weeks!!!

Very unlikely.

I have since received a brand new CPU and still have the same issues.
My fans run, the LEDs on the MoBo and case light up, and the drives
can open and everything. All I can think of is that my motherboard
is possibly faulty. Any help would be greatly appreciated. I've

Ensure that you have the small square 4 pin 12V power connector connected
from the power supply to the motherboard. Thats likely your problem.

If it isnt that, see what happens with no ram, it should whine about the lack of it.

If that doesnt help, try resetting the cmos.

If it does whine about the lack of ram, try different ram.

Could be motherboard bad. First try to clear the CMOS battery jumper. Is the
CPU fan plugged into the right connector?. Remove everything, including
video card, and run with just RAM, CPU+HS/fan, and power supply. If you have
an old PCI video card use that. Do you get beeps from motherboard? Be sure
CPU is plugged in correct direction and heat sink is firmly seated. If still
nothing then try different motherboard.

I just built a new system, most of the parts ordered from Newegg also.
I have an Athlon socket 939 setup, my EVGA motherboard has a numerical
display. The error code pointed to a bad bios chip. I got power,
fans, led's, but no post as well.

It turned out to be a bad mobo, I RMA'd to Newegg, they didn't carry it
anymore, got the same one from another online vendor and now I'm up and
running.

Could be PSU!! A 500W PSU for $50 is rubbish! You will have nothing but
trouble with it. You need to pay double that for 500W. Don't forget the 2x2
power connector to the motherboard.
