Thank you to all the volunteers, whether you're able to offer help or not!

FULL disclosure: I was running AVG PC tuneup (http://www.avg.com/us-en/avg-pctuneup) last night when I went to bed.

When I awoke this morning my PC was dead. When I turn on the power I get no beeps. No signal is sent to the monitor. The monitor is working. Everything is plugged in properly. I unplugged all external devices, same RESULT. I removed all RAM. Still no beeps. I put the RAM back in, nothing.

All fans are running, optical drive still opens and the lights on the RAM still blink - so I assume the power supply is good. Is that a fair assumption?

The computer is about five years old. It's an Acer Aspire X1470. The MB inside is a DAA75L - aParker 48.3FU01.011.

I can find the same MB on Amazon, but would have to wait for arrival. Ideally I'd LIKE to purchase locally from http://www.ncix.com/category/motherboards-64-107.htm , but I am unfamiliar with what specs to look at to be sure I get the same size, etc. MB. I rarely use the PC these days so a cheap MB is all I need. I only use the PC for word processing and internet - no gaming/video/etc.

If I'm missing a potential solution/fix, please share! Otherwise a MB recommendation would be awesome.

Thank you again!I'd start with a power supply swap. The symptoms are very common with a power supply that has failed and is giving out low voltages so the SYSTEM cant truly start 100%.Thank you! I will try that first!
