Resume from Sleep or Hybrid fails but resume from Hibernate succeeds - W7Ultimate32
If I choose Sleep (with or without hybrid), resume gets stuck, everytime, PC fans & lights work but no video. If I choose Hibernate, resume works fine. I checked my memory (2G DDR2 667) with memtest for several hours no errors. I also installed KB977178 (hotfix for resume with big disks) hoping it would help but it didn't. I also looked at the event viewer logs but there are no events for the failed Resumes, and the before Sleep events had no errors/warnings. My video card is ATI HD3850, CPU is AMD 4600X2. Chipset is nForce 550. Latest drivers/bios. Latest Windows updates. Note: I previously had nVidia 8600GT video card - resume from sleep was failing at ~50%. Now after changing to ATI HD3850 it fails 100% of the times. Resume from Hibernate succeeds 100%, for both video cards. Any ideas how to trace/find/fix the problem? Thanks, raananh

Hi, I would like to suggest you update the BIOS and the hardware drivers first. If it does not work, I also would like to suggest you test the issue in Clean Boot. What is the result in Clean Boot?
