It takes some 4 - 5 minutes to boot, with long periods of zero apparent HD activity, a minute's "Welcome" screen and a couple of minutes' blank blue screen. Then the Systray takes a minute or more to populate with the usual ZoneAlarm security suite, speaker volume etc.
In addition, the following (not even comprehensive!) happen intermittently. (A "*" signifies more often than not)
All open windows lose the input focus - can't close or minimise anything.
Everything freezes and I have to switch off the power and reboot.
*The hourglass runs permanently on a "done" pane.
*The bootup stops with a "STOP" message on a blue screen, followed by - typically - STOP : 0X0000008E (0XC0000005, 0X804EEEAD, 0XF7F88B90, 0X00000000). (The numbers vary from boot to boot).
* I switch to "Standby" using the keyboard HP standby key - but half an hour later it switches itself back on.
CTRL>ALT>DEL does absolutely nothing, or if it does bring up the usual pane it won't stop a non-responsive program.
*It can take a minute or more to close a window after clicking on the cross.
As I said these are just a few of the odd things happening these last few months
There doesn't appear to be any unusual or constant HD activity, I run antivirus and antispyware programs daily and keep them updated daily and I'm going potty!
I have run a RAM check program for hours at a time with no errors.
