First, computer specs: 5 yr old Acer Laptop, AMD Turion 1.6g, 100gb HD, 1lmost 1.5gb of memory, running Windows 7 Ultimate 32bt w/sp1. Also installed Ad Aware 9.
Computer running well, and would hibernate upon closing the lid, without issue. I saw that Ad Aware had released version 10 Free, so I uninstall v9, restart, then install v10 from Lavasoft website. Install goes well, but now when I close lid, computer will not hibernate, and after short time, will produce BSOD labeled "driver
power state error", with stop: 0x0000009f. If I uninstall Ad Aware, hibernation resumes perfectly. Have not tried with other antivirus programs, but would consider another free version if one is recommended.
Attached is BSOD crash folder and perfmon report,
