Answer» When I start up my laptop, the BIOS screen and Windows LOADING screen are jumbled, and this leads to a blue screen page fault. However, I can start up in safe mode just fine, and after uninstalling all my video card drivers, I can start up in normal mode as well, but Vista automatically reinstalls them and the problem happens again. There's no WAY for me to cancel the reinstall. First of all, you should probably stop using the acronym BIOS. A sincerely doubt you mean bios. EXACTLY what do you see when you boot and how far does the boot get? Second, if the driver is a 3rd party driver then Windows CANNOT automatically reinstall it if you actually uninstall it. I'm sure that I do mean BIOS, but okay. My BIOS splash screen is jumbled, and it's also jumbled when I enter the menu, but not so jumbled as to be unreadable. The Windows load screen is also jumbled, with only the loading bar visible. I get a blue screen after Vista finishes loading, and the computer shuts down. With my nVidia card disabled, it boots normally, but the jumbling is still there most of the time. 1. From Device Manager. I uninstall the nVidia drivers completely and attempt to install a different (updated) driver set after I reboot, but Vista automatically reinstalls and re-enables the device. 2. The current one was shipped with my computer. I can't update it, as I said, newer drivers from the nVidia site and Sony site simply refuse to install, saying they're incompatible, despite the fact that they were made for my exact model of PC and video card. 3. Absolutely nothing. I just got a blue screen out of nowhere today, and since then, I've had this problem. System restore to a month ago didn't help.

My BIOS splash screen is jumbled, I'm sorry, but you are obviously not qualified to help me with this problem. Just so you know, uninstalling the nVidia drivers from add/remove programs launches the exact same uninstaller as doing it from the device manager, and Vista reinstalls them automatically on restart anyway. However, I did manage to manually delete the folder with these drivers so this isn't happening anymore. I still cannot install any different drivers from the ones that come with my restore disc. The blue screen is a generic "Page Fault in Nonpaged Area", which could mean anything. You know. A page fault, like I said. The easy answer is to replace the laptop, but I've heard of people fixing these problems by reinstalling their drivers, so I am basically hoping somebody has an idea of how I can do this or why it's telling me they are incompatible. Sony will charge me $40 just to ASK. For the record, it's a Vaio with an nVidia GeForce8400M GT card.

The REASON you are getting blue screens with the NVidia driver and the "normal" (generic, safemode, what it uses when you disable the Nvidia driver) driver works/sorta works is because the generic driver isn't trying anything specific; it's telling the video card to perform actions that almost all video cards will support. This also means no support for anything 3-d or fancy or anything. What is probably happening is the NVidia driver, as with any driver, tries to communicate with the card, and because of various hardware based faults it's getting unexpected responses to the IO commands to the point where it has a problem (tries to allocate too much memory, tries to access a null pointer, whatever) and blue screens. Normally, the "jumbled text" issue with text-based applications (such as the BIOS) are caused by problems with Graphics memory; these could be the cause of all your problems, in fact. Since, however, many laptops use a shared memory architecture, it could also be your system RAM. If your system is using shared Graphics memory, I'd go ahead and run memtest86 on it- first reduce any "shared graphics memory" option in the BIOS to as low as it will go (thus allowing more RAM to be tested by memtest86). Also, if you do have an option to use "dedicated Video RAM" (or SOMETHING to that affect) try disabling it (thus using system RAM) and see if that clears up your problem.
