About 50% of the time, my system will get part way through the boot process and then reboot. After the reboot, everything seems to work fine. I didn't do anything significant to my system prior to the start of this issue. I've done a virus scan and found nothing. After a reboot, Windows offers to send an error report to MS. Here's what it contains: BCCode: 1000008e BCP1: C0000005 BCP2: A83E733D BCP3: A5170B0C BCP4: 00000000 OSVer: 5_1_2600 SP: 3_0 Product: 768_1 I've checked the Event Log and I get 2 Event ID 7000 on every boot and reboot. One is: The adfs service failed to start because the system couldn't find to file The other: The NetBEUI Protocol failed to start because the system couldn't find to file I checked the MS tech info and was advised to do an sc query. The results for sc query adfs are: Type: 1 Kernel_Driver State: 1 Stopped (not stoppable, not pausable, ignores)shutdown) WIN32_Exit_Code: 2 (0x2) Service_Exit_Code: 0 (0x0) Checkpoint: 0x0 Wait_hint: 0x0 The results for sc query NetBEUI are: [SC] EnumQueryServiceStatus:OpenService FAILED 1060: The specified service does not exist as an installed service. I'm using Win XP SP3 fully updated. I have a 1TB HDD which is less than 50% full. I have 2GB of RAM and am using 729 MB as I type this message. I'm pretty good with the computer but I've reached the limit of my ability on this issue. Any suggestions?
