Hi - I have a P7P55D motherboard on a desktop, maybe 6 years old, Running Windows 7 professional. The PC seems to be going into sleep mode but not waking up. After a power off/on cycle it comes back - until the next sleep timeout. Have just changed the sleep setting to Never, see if that works. However is there a diagnostic that can be run or other tool? Or any advice from you? Thanks - PJ
 
Solution
You can always do a BIOS reset with the Motherboard's CMOS jumper if worse comes to worse. That will set the BIOS back to its default settings. So if you made any changes you want to keep, make note of them.
