I have an Acer Aspire 6930Z running on Vista Home Premium SP2.
I know it's old, but has been running reasonably well up until a few days ago.
The slowness has not been a gradual thing ................ it just started happening a few days ago.
It'll quite often just freeze for several minutes before continuing.
It now takes far, far longer to boot up and today I had a black screen with a moveable cursor for over an hour before it finally decided to boot up, although it boots into 'Safe Mode' quite quickly.
I'm sure it's not an infection and I'm fully Windows updated.
Finally, sometimes it won't shut down properly.
When shutting down the programs will close and the screen will go black, but the power button remains illuminated.
It's like this for a few mins before going to a BSOD for about 30 seconds, after which it reboots.
The Blue Screen basically says that a problem had been detected and windows has been shut down to prevent damage to my computer.
It also says DRIVER_POWER_STATE_FAILURE.
Further down it has the following,
STOP: 0x0000009F (0x00000003, 0x85524B70, 0x890A2020, 0x88CF0008)
Collecting data for crash dump.......
Initializing disk for crash dump........
Beginning dump of physical memory.......
Dumping physical memory to disk : 35
Obviously the 35 is a percentage and when 100 was reached my machine rebooted to my desktop.
Then it can be shut down without any issues!
Sorry for the information overload, I'm just assuming the more info you have the better are the chances of finding the source of the problem.
Thanks in advance,
