No Boot

[summerpewp]

Receently purchased a pc and built it. The following purchased items are :

AMD Athlon 3800+ am2
MSI K9N Neo am2
Fortron 450 Watt
Corsair 1 gig ram DDR2
Coolermaster Centurion 5
Nvidia 7600GT

It wont boot. We get no signal to the monitor.

Our attempts at discovering what was wrong.

Rebooting the cmos by removing the battery and jumper for a few minutes. No change
Removing and reinserting the video card, no luck
Checking all connections, no luck
Removing hard drive to see if it may be that, no luck

We get all fans spinning, and hard drive sounds like its alive.

Any help or suggestions would be great.

Only thing is, we dont have items to do a swap for. So let me know if you can figure this out without doing such a task.

Ensure that all of the power cables are connected. Looking at a photo of this motherboard, I see a 24-pin main plug, an 8-pin ATX12V receptacle, and a 4-in-a-row receptacle just above the video card slot, so that's three connectors. Got them all hooked up as shown in your MSI owner's manual?

Also check the MSI manual to confirm that you got the RAM into the correct slots for a 2-stick configuration (I assume you have 2 x 512MB there). And check the Clear-CMOS routine... you need to unplug the system from the wall, and sometimes both remove the CMOS battery and cycle the jumper to clear the CMOS.

If that doesn't get you anywhere, try removing the motherboard from the case, lay it on cardboard, threaten it a bit (they fear water), and then try firing it up outside the case on cardboard, with only the minimum items that are necessary for it to POST. No keyboard, no mouse, no drives, no extra cards except the video card, no extra case wiring. Good luck! 🙂
