I'm using BIOS 1005, and I think I have an issue with my drive's spinning down and then not spinning up when they're supposed to. I was getting freezing like symptoms after I'd leave the computer for a little while (much more time than the HD spin down time I set), and then not being able to open IE windows, My Computer, etc. MSN would still work, but eventually the whole thing would freeze and even if I tried to power down, the HD light came on and flickered a bit, but it wouldn't shutdown.
Ran chkdsk /r on both drives (WD 200 and 250gb 8mb SATA's) as well.
The windows install is 2 days old, with the latest NForce drivers from Asus's website.
Also, I have a super low +12v rail it seems.
I adjusted my PS so that it puts out 11.80 and 5.06, at the BIOS post I get 11.56 and 4.85, however SiSoft Sandra tells me 11.29 and 4.85.
Measuring at a Molex connector with a Digital VOM shows taht +12v never drops below 11.77v under any amoutn of load, and +5 never goes below 5.04.
As I understand, the voltage monitor is after the MB's voltage regulator, so it's possible that the board's voltage regulators are just not putting out the power?
ASUS has been known to use the highest quality voltage regulators, so I wouldn't immediately suspect that. Hard drives randomly spinning up and down is most likely your 12v rail. I had this problem with an A7N8X-E board. After I replaced the PSU, the problem never came back.
I kinda doubt that too, well I hope it's just reading low.
Interestingly, I have an 80mm quad blue LED fan connected to a Chassis fan header, and I measured 11.70 volts across it.... when the +12v was measuring 11.80 at both a HD Molex and the +12v 4pin MB Molex connectors.
The HD's aren't throwing any SMART codes, but the chipset fan on the board and small fan on my X600 make it impossible to hear if the discs actually are spinning up and down.
