I've had my P5K-E Wifi for four days. Everything is good, except it did not wake up from Vista's "sleep" mode this morning. The fans, lights, and hard drives turned on, but nothing happened. I hit reset and it started right up...
This is a known issue. I bought the board anyway. Normally it starts up just fine.
Edit: It booted up fine today (the next day). In total, the failed boot accounts for only 1 out of about 10 boots.
