Powers Up; Won't Boot

Asus P5n32-sli deluxe motherboard
August 31, 2009 at 18:20:35
Specs: Windows XP, 2 Gig
Wierdest thing I've ever seen. This new build ran flawlessly for about a month before developing this hitch. When powered on it starts all fans, cycles through the CD and other drives and then presents a blank screen. It doesn't even get to the initialization messages.
Blank screen, all fans humming.
BUT then, just as reliably, it will re-boot perfectly if I use the RESET button. Every single time this is how I must turn on my computer. And after the RESET - Voila! - it works perfectly, even better than most.

Until the next day.....when I go to power it on.

Did you download or install something before that happened?

I would also look at the PSU as the problem.

Jam -
Good point. The PSU is the Enermax Infiniti, a 720watt modular unit that runs full power at 40 degrees C. The input current rating is 4-11amps.

I thought this was more than enough juice. I'm not running an SLI set up (even though the board can accommodate it).
Your thoughts?

Thanks in advance,
Connell

This condition didn't abruptly develop but rather grew over time. At first it only exhibited this reset-only boot characteristic occassionally. Now it seems permantent.
I've run register cleaners and all manner of system diagnosis. In particular, I've thrown everything CC (crapcleaner) has at the problem. Once my rig is running it works flawlessly and fast. It's just this funny booting thing.
And I have never had any games on the machine. It's purly used for video and graphic editing.
So I'm not thinking it's a software conflict.....even though I like them better than hardware problems.
Whatchathink?

Check the settings for your RAM. Voltage settings and timings. May need to set manually. Your RAM may require more voltage than the standards.

Also exhibits symptoms of a poor connection somewhere. Re-seat everything but the CPU/HS. Snap the RAM in and out 4 or 5 times to burnish the contacts.

Power supply sounds more than adequate. That said, check the voltages in PC Health to verify they are running close to specs.
