Can't boot

[winx62]

I am building a new computer with the following specs:

Asus A7v600-x
Athlon XP2600
ATX Case
512MB Kingston RAM
20GB Seagate HDD

I start the computer and it wants me to flash the BIOS, so I do so, I am sure it is the right file. Then I can get into the BIOS, so I load setup defaults and then it restarts but the main "ASUS" screens comes up then the screen flickers and it just goes blank and the monitor shuts off, I'm not sure what to do now. I checked all the jumper settings and they are all good, set to the defaults.

Anyone have any ideas?

Thanks in advance.

Make sure you reset the CMOS memory by setting the jumper of the mainboard.

Yes, I did reset the CMOS previously, any other ideas?

Have you barebones booted the system??

Here's my canned spiel for initial building:

For new systems it would be wise to barebones boot the system initially. This is best done on a non-conductive surface such as a piece of cardboard on a table.

Connections from the case/power to the motherboard are accomplished outside of the case on the table.

Barebones is only the RAM, Video Card, Monitor, P/S 2 Keyboard...and of course the CPU>Heatsink>Fan...

See if you can make it through POST with this barebones approach...

Reboot, setting the BIOS to boot from floppy first...usually, the (0) choice, save and exit...shutdown.

If this worked add the floppy drive.

If the system booted again successfully, shutdown and reboot using a RAM tester such as: http://www.memtest86.com (http://www.memtest86.com/)...these are self booting.

If all is well, shut down and add the harddrive. If the reboot is successful recognizing the harddrive, I then shutdown and reboot using a floppy with the Harddrive's diagnostics (downloaded from the manufacturer's site)...these are also self booting...

If all systems are go, proceed to add an optical drive capable of loading your operating system...

The concept is to load one hardware device at a time which provides for troubleshooting as well as assembly of the computer. If, at any time you encounter a no boot situation, the last hardware item you added is more than likely the problem.
