I got a bluescreen hours ago on my Toshiba Satellite U400 Laptop using Windows Vista. I can't exactly pinpoint the cause but this is what the bluescreen says ------------- A problem has been detected and Windows has been shut down to prevent damage to your computer. A process or thread crucial to system operation has unexpectably exited or been terminated. If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps: Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need. If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory operations such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode. Technical information: *** STOP: 0x000000F4 (0x00000003, 0x88253B18, 0x88253C64, 0x82C82430) Collecting data for crash dump ... Initializing disk for crash dump ... Beginning dump of physical memory. Dumping physical memory to disk: 100 ----------------------- I cant pinpoint the exact cause but here are some infos and problems with my laptop: 1. For the last 6 months I have problems with the Hibernate and Sleep options with Vista because most often laptop will not switch the light of the power button off and also some other lights dont turn off but screen is resting. I see it working correctly (lights are off) about 1% of the time I use hibernate/sleep mode. 2.I saw some ants crwaling out of my keyboard and i stupidly pat the back of my laptop upside down for about 4 minutes and i did that for 2 days (that would be 3 times all in all). I did so lightly cause I don't want to spray insect killer on my laptop. But after doing it everytime I oepn my computer it would operate correctly until a half day after my last patting. I was able to use the Linux OS (my laptop's on dual boot) and then when I logged on to Windows Vista, after having the hibernate problem again, when I rebooted the PC, the desktop showed for 2 minutes and then there went the bluescreen. right now I am using Linux OS on my laptop. could the problem be on Vista? I read that most dump crash is 99% hardware caused but I am able to log on to Linux OS. Please help me. I'm new here in troubleshooting stuff and I will appreciate any help. Thanks.

I ran the safe mode and after viewing some files, one folder hang and then PC restarted. the safe mode since then hang for every application/folder I open i did checkdisk twice, startup repair once and safe mode and open folders twice. hope someone helps. thanks

... have you tried setting the bios to default? ... do you have two harddrives in your laptop? found this: 0x000000F4 (0x00000003, Parameter2, Parameter3, Parameter4) ... This problem occurs on a computer in which Windows XP or a later operating system is installed on a hard disk that is configured as a subordinate and no other device is connected to the same IDE controller channel (primary or secondary). ... source: http://support.microsoft.com/kb/330100 *************************************************************** ... you're not the only ant host . . ...

After some trying the normal boot again, I got another type of bluescreen that says on the follow these steps part: Check to be sure you have adequate disc scpace. If a driver is identified in the stop message, disable the driver or check with manufacturer for driver updates. Try changing video adapters. Check with your hardware vendor for any BIOS updates. Disable BIOS memory options such as caching or shadowing. If you need to use Safe mode to remove or disable components, restart your computer, press F8 ...

Using Startup Repair doesn't solve the problem, I can see the desktop for a while in normal mode but then it doesn't update the desktop anymore (ie the time, you cannot open applications and folders) Diagnosis and repair details shows: Startup Repair diagnosis and repair log: ------------------------------------ Last succesful boot time: 9/25/2009 1:00:58 AM (GMT) Number of repair attempts: 1 Session details -------------------------------- System Disk = \Device\Harddisk0 Windows Directory = C:\Windows AutoChk Run = 0 Number of root causes = 1 doing system restore (for three different retore points - 9/23/2009, 9/27, 10/2) also doesn't help: System Restore did not complete successfully... Details: System Restore failed due to an unexpected error. Cannot create a file when that file already exists. (0x8007087) ... Last Windows update shows it was on 10/2 I hope these set of information help. Thank you sir.

i'll try setting BIOS to default, but from what I read in your link, it happens only for XP and 2003, and not vista/longhorn. but anyways, thanks for the help. and the ant host thing. haha

update, i tried safe mode again and got in, with a window notifying that a system restore is made. but when i opened my computer the desktop restarted. i made a system restore again and after it finished and booted the normal mode, it hang again but with farther booting compared to yesterday's. please still help. thanks.
