Well got this motherboard a P5Q SE PLUS great motherboard stable as a rock but had one little annoying problem my computer refused to go into sleep mode was very annoying. After fiddleing with this for 2 hours i figured out the fix for it so if you have this motherboard you might want to try this.
Main thing is it locks up in sleep mode and the culprit is usually your USB keyboard and mouse so easy fix go to device manager and go to your mouse and keyboard properties and in the power management tab uncheck allow the device to wake the computer do this for mouse and keyboard.
2 other things i did was in bios in power setting suspend mode put on S3 and enable ACPI 2.0
I'm sure im not the only one with the sleep locking up problem on this board
