Windows 7 64bit Boot loops waking from sleep mode

[Tank997]

When I try to wake my machine from S3 sleep mode I see the hard drive lights power up but nothing happens, I get a black screen for about 5-6 seconds then my machine proceeds to boot loop itself until i manual shut it down with the power button.

Sometimes it will start up regularly with no problems, and about 60-70% of the other times it will do the problem i have explained above.

Id really appreciate any help on this it is driving me crazy.

Most sleep problems are Display Driver related. Update yours now. If newest, try another recent one.

Enter Power Options, on Balanced plan, set Sleep to 1 minute, Hybrid Sleep on, Hibernate to 2 minutes. Observe what happens. Will it shut down after hibernating, then resume normally?
