Lenovo ThinkPad T61. T7500(2.2GHz), 2GB RAM, 160GB 5400rpm HD, 14.1in 1400x1050 LCD, 128MB nVIDIA Quadro NVS 140M, CDRW/DVDRW, Intel 802.11agn wireless, Bluetooth, Modem, 1Gb Ethernet, UltraNav, Secure chip, Fingerprint reader, 6c Li-Ion, WinXP Pro This machine has been very good until now. Here is a list of error reports this week. These errors occur after the machine is idle for a few minutes, up to the time (30 minutes) I have the screensaver to start. From what I can tell, instead of going to the screensaver, it shuts down. But in some cases it could be after the screensaver starts. Windows Error Reporting Stop (blue screen) error caused by a device or driver You received this message because a hardware device, its driver, or related software has caused a stop error, also called a blue screen error. This type of error means the computer has shut down abruptly to protect itself from potential data corruption or loss. In this case, we were unable to detect the specific device or driver that caused the problem.

How do I post them, and find them. Or do I need to? I'll try doing the diagnostic scans mentioned also in those earlier threads. Took me a while to get the name of the HDD (Hitachi). Had to first figure out how to open the case. As the Hotfix report mentions sql, I do have a MS SQL Server 2005 that I cannot install the latest MS update for. There's a workaround for this but it's pages long. A weekend project. Any advice for these problems would be welcome.
