I have a client's laptop that, on startup, start churning so badly it becomes completely unresponsive. I can get past the login screen, but after that it essentially freezes. Booting into safe mode is marginally better - I can bring up a taskmgr - and see that CPU and RAM usage are both low. Hardware diagnostics pass fine, and I can boot other OS on the machine. I've scanned the entire hard disk for viruses, with no hits. This has happened to the same machine twice in the last month, and the user has said they didn't install anything (or do anything funny) since the last re-image. I'm hesitant to re-image it without diagnosing the problem first, as I fear it might just come back. Any ideas?

Have you ran a disk checking diagnostics of the hard drive. My initial gut feeling is that the drive may be bad. Try using a bootable PC repair kit and run a diagnostics on the drive. Hiren's boot CD has some great utilities all rolled into one for PC repair/diagnostics. Also, if you wish, you can use a USB drive to boot from. I recommend using pendrivelinux to set that up. I actually posted a detailed how-to on how to use pendrivelinux if you need it here Finally, here is a guide on how to check the health of the drive. | ||||

In the Task Manager, add the I/O columns to the process tab to show how much disk I/O is being used by each process. In the Processes tab, click View > Select Columns, then check the columns for I/O. Better yet, run the Resource Monitor. Go to the performance tab of the task manager, then click Resource Monitor, or run | ||||
