Approximately once every couple of weeks my tx2500 seems to freeze before the login screen in Vista 32bit. Here is exactly what happens: 1) I turn on the computer and the initial HP logo shows up 2) The windows vista start up bar thing (the 4 green vertical lines) starts to cycle through but extremely fast (much faster than a normal start up). 3) The screen goes to a black screen then goes blank. 4) (This sometimes happens) Sometimes when I push keys on the keyboard or touch the screen, the computer goes to the login screen. I am able to log in but then the Vista Progress Circle starts to cycle extremely fast and then goes to a black screen again. I have to restart my computer by holding the power latch until the computer shuts down. On two occasions this has happened again after I restarted, but the rest of the time my system starts up as normal. Though this is a reoccurring problem I would probably not be able to send in my laptop to hp anytime soon since I use my tablet as my sole notebook and study materials (notes, onenote) for classes. I am also worried that when hp does receive the tablet, the problem will not happen and they will simply ship the laptop back to me and state that there is nothing wrong. I am wondering if anyone knows what the problem could be? Software or hardware? Is anyone else having this problem? Please help. Thanks.
