HP Pavillion dv6-6033cl Entertainment Notebook PC
After waking from sleep, the screen is first box-like, then after a moment or two, bounces back to fill the laptop screen. This started a couple of weeks ago. There has been no new software installed, no new downloads; Windows updates automatically as well as McAfee. McAfee reported a Trojan just prior to this happening but removed it.
This does not happen when I start up the computer.
What I have already tried:
System Restore to the time before this happened
Safe Mode and re-boot (can't test in Safe Mode because computer doesn't sleep in Safe Mode)
Selective Start Up
Windows Defender Offline scan
Checked that the monitor is detected
uninstalled and re-installed (it is the latest driver)
HP Utility Tools and diagnostic tests
BIOS and chipset driver updated
Disabled the graphics driver but in lower resolution the computer doesn't go to Sleep
Uninstalled McAfee (problem persisted and I re-installed it)
This is not a major problem but I would appreciate any help you can offer.
