Hello - Help!, My Windows Vista Ultimate keeps committing Harri Karri!!. Generally, the screen will state it's Refresh Rate is incorrect then simply freeze, not allowing me to do anything but press the restart/reset button on the PC to reboot. Other times, it simply reboots it's self with no obvious visual warning or reasoning in doing so. I have no hardware/driver warnings, I have seen errors in the Event Viewer suggesting an Hard Drive error, so have run CHKDSK which has highlighted bad sectors and then used the third party application "SpinRite" but it would seem to no avail. I have attached the last few minidumps in the hope someone may be kind enough to diagnose and help. I'm at my wits end with this!, I'm loosing awful amounts of work/time due to this occurring between saves. Any help would be gratefully appreciated - Thank you!
