    It is an 0x50 error, PAGE_FAULT_IN_NONPAGED_AREA; Invalid system memory was referenced. This cannot be protected by try-except, it must be protected by a Probe. Typically the address is just plain bad or it is pointing at freed memory.

    Your minidump's analysis revealed that it was caused by nVidia drivers's nvlddmkm.sys (the driver's time stamp is relatively older i.e. May 12, 2007).

    First of all, uninstall your currently installed driver; download Driver Sweeper or Driver Cleaner Pro, and remove any traces left from uninstallation. Then download latest drivers supporting your graphic card, and install them.

    Lastly, download OCCT and thoroughly stress test your graphic card/and its memory.

    You can get it from If it is one of those models with shared memory for graphics, then the problem may be with your RAM.

    ok i installed the driver from the vaio support site cuz that is what said was required. i still cant start in normal. if it were the RAM. how would i fix it. on a side note the Viao logo is distorted and there are dots throughout the screen when windows is loading incase that could provide more helpful clues.

    Ack, that pretty much sums it up, probability is your viao's graphic chip is shot, unfortunately it can't be easily replaced on a notebook. Right now, better approach would be take this notebook to a good technician near you, and see if something can be done about it. But I must add, if its an onboard solution, you may need to get the whole motherboard replaced (and it will be costly).

    Well lets hope it will last bit longer, but don't count on it for any 'critical work you need to get done / and backup your data' as a precaution. Just in case, if the display dies due to these issues, at least you'd need not to worry about your data.
