BSOD on start, Startup Repair: Unknown Bugcheck: Bugcheck 3d
We've been getting a BSOD on one of our computers on startup recently. The exact message the BSOD gives varies but often mentions atapi.sys. Having done extensive research we've come to the conclusion that it could be a rootkit or it could be the fact that we have Daemon Tools installed on the computer. The problem is, when the BSODs first started (entirely at random - we'd done no updates and changed nothing, except perhaps to install a game or two, not sure), repeatedly trying to start the computer would eventually make it start (after 4 or 5 attempts) and it would be fine after that, but they've gotten worse and no matter how many times we tried, we've been unable to make it start, safe-mode or otherwise. If only we could get the thing to start up, we could run heaps of rootkit scans.
We'd really rather not do a format and full reinstall, so we're looking for solutions that can be done by hand.
So far, we've tried renaming atapi.sys and copying a fresh (hopefully clean) version from a different computer via Recovery Environment's cmd prompt, but the BSODs still occur. We've tried Startup Repair, but it gives this message:
We have no USB keys plugged in when doing the Startup Repair.Code:Root cause found: Unknown Bugcheck: Bugcheck 3d. Parameters = 0xfffff88002ffb020, 0x0, 0x0, 0xfffff88000e012b8. Repair action: System files integrity check and repair Result: Failed. Error code = 0x490
Specs:
Windows 7 Home Premium x64
Intel Core 2 Quad (can't remember the exact model)
4gb Ram
GTX470
MSI MS-7528 Motherboard
We're dual-booting two harddrives. One has Windows XP on it, the other Windows 7. The XP harddrive boots fine, but the 7 drive BSODs every time.
We cannot boot into Windows, safe-mode or otherwise.
Any help would be much appreciated :)
