Problems getting video signal at boot - new PC

[stratocastx]

I finished building a new computer on Saturday night, worked fine through about 10 restarts. Downloaded the latest Geforce drivers. This morning I go to boot up, and I get no signal to the monitor. Checked all the connections, nothing lose. I press reboot on the machine and it all goes back to normal and works fine.

Now, half the time I boot up, I won't get a signal, and the computer speaker will NOT beep at startup. The rest of the time I boot up, it will start up fine, and the computer speaker DOES beep.

My specs:

Asus A8N-SLI
512x2 Corsair Dual Channel DDR
Maxtor 200 GB SATA HD
BFG 6800GT OC
Pioneer 16x DVDRW
AMD Athlon 3500+
BFG 550 watt PSU that came with the 6800GT
Asus Star Ice HS/F
Arctic Silver Ceramique compound

My monitor is about 3 years old - a 17" Samsung CRT. I'm hoping it's an issue with the monitor and not the video card. The video card works perfectly outside of this issue. I plan on getting a new monitor within a week.

I would be grateful for any advice. thanks

I think it should beep no matter what. Should be something else besides the monitor.

If it doesn't beep that means its a problem with your system, not your video card or monitor. Your computer is not POSTing half of the time. I'm not sure what the problem is from there though.

Hate to say it, but it sounds like it could be the PSU to me. One of the symptoms of an underpowered PSU is a failure to boot, or it won't POST after power-on, but hitting RESET once or twice will do so, after everything else has already been powered-up.

Otherwise, check to make certain that everything, especially the video card, is fully seated into the slot, and nothing is shorting out anywhere.
