Hi all, Last week i built my new case with all the same hardware plus a new WD Raptor harddrive which now functions as system disk. I installed the software as I always did cuz i never had BSOD problems in the past. My OS is Windows XP Pro SP2 with all updates and I used all the same drivers that i always used. Except for the ATI driver cuz there was a newer version available, which i downloaded and installed. Then i got the reboot problems, related to a faulty device driver, but the error message wouldn't tell me which device driver. So i thought i must've messed up somewhere and i did a fresh install again. But the problem persisted. After installing the latest Java Runtime i got my system in a boot loop and with System Recovery i determined that the Silicon Image Raid controller was causing the boot loop. Since i don't use that i disabled it in BIOS, removed the driver and the boot loop was gone. But unfortunatley the device driver reboots kept coming every now and then. I removed the new ATI graphics driver (Catalyst 5.11) with the one i was using before (Catalyst 5.7). No luck, still reboots now and then. Additional info: My former system disk, a Maxtor 120gb SATA has a few bad blocks and when formatted it gave a lot of error entries in my system log. But it never gave me reboot issues when i was using it as system disk. It was just noisy now and then but it works. It's now one of my data disks. And since the information from the Microsoft error report tells me it's a device driver problem i doubt that it's the cause of the reboots. So could someone please analyze my minidumps for me to determine which device driver is causing the trouble please? I have already made debuglog.txt files, as described in another thread to make it easier for u experts and in the filenames i added the system log event id's and error code for that minidump. There's 1 minidump for the Silicon Image Raid Controller driver error (fixed that, but just for additional info), 1 file with my system specs and 3 minidumps from the device driver errors that i'm still having. You can find the files HERE . Please help, i would really appreciate it .
