i got an issue with VISTA. when my computer boot up after the welcome screen, every thing load up real fast then the hard drive just stop running. 20 sec later it starts to run again. during that 20 sec delay i cant open some programs. EX: diskeeper. it says the service is not started. but after that 20 sec the screen blinks and the hard drive start running again. and i can open any program now. help me with this, i hate this problem. the same with the control panel, network etc.the same thing happens with the wifi network. during the 20sec delay the HP wireless Assistant does not appear and the network system icon has the red x. but i cannot access the network center (nor the control panel).then the screen blinks and the HP WA appears, connects to my works network and everything goes to normal.in the event viewer (performance log) i noticed this message: Windows has started up: Boot Duration : 61354msIsDegradation : falseIncident Time (UTC) : 02/03/2007 20:13:26P.S. my laptop is: tc4400 (tablet pc), core duo 1.83, 1.5GB ram, NTFS 80GB HDD. it came with windows xp tablet pc 2005 preinstalled and i bought vista ultimate x86 (32bit) and did an upgrade. i installed all the hp compatible version from the hp support site.P.S.2) i made a complete pc backup and tried the "clean installation" method. the same thing. aftes installing all the drivers it has the same delay. (during the early reboots it didnt have the exact 20sec delay but it had a 10-12sec delay in the logon screen after typing the pass - welcome). i the upgrade installation i noticed only a 3-4sec delay in the logon screen and the full 20sec delay when the processes start.P.S. 3) with windows xp the statup was a 10sec "job" with no delays and errors...thank you in advance.
