I'm trying to fix a Sony Vaio Desktop (VGC-RB60G) for a friend. This is the first Sony PC I've ever dealt with and I'm realizing that they make it very difficult to do a complete windows reinstallation. So far I've learned that they do NOT offer a plain reinstallation cd but rather a set of Recovery discs which will only restore the system to "factory" condition (with all the junk on it). Anyways, the original problem with the PC was that it often had the BSOD error, 'Page_Fault_in_Nonpaged_Area'. So without any recovery discs available I used the F10 option at bootup to get to the Sony Recovery Partition to restore the C: Drive to factory condition. However, after completing this process, steps 1-4, the BSOD error stopped but instead Windows would repeatedly crash and give the "Windows has recovered from a serious error" message when it restarted with 2 files being the culprit which were located in C:\Documents and Settings\Username\Local settings\Temp\WER9507\Mini082710.dmp and also the sysdata.xml file which is located in the same directory. Instead of deleting those folders I tried using the Recovery Partition to once again restore the C:\ drive thinking the original restore did not work properly but I couldn't even get through the second restore process because of the constant crashing which has gotten even worse. Now, I can't even get into Windows because the Restore process did not complete and I'm actually in a worse position than when I started. Is this a hard drive failure? If I obtain a set of recovery disks from Sony can I expect to be able to reinstall Windows without the crashing? Should I delete the mini-dump and sysdata folders and if so can I do it without booting up to Windows? Any help will obviously be greatly appreciated! Thanks!
