Dump files are stored in C:\Windows\Minidump, or as the file MEMORY.DMP in the C:\Windows directory (which is overwritten with each memory dump). If nothing is located there, search the entire hard drive for files ending in .dmp There are many reasons for a dump file not being created - so that will be a part of the analysis.

You've done most of what is needed (and thanks for that!). Depending on what you removed with the SpyBot, there may/may not be a malware component to this issue.

Frequently hibernate and sleep issues are due to a corruption in the video drivers. So I'd suggest:
- Downloading the latest video driver for your system from here: http://support.dell.com/support/down...&catid=&impid=
- Uninstall your current video drivers through Control Panel...Programs...Uninstall a program.
- Reboot the system (dismissing any "Found New Hardware" dialogs that may occur).
- double click on the downloaded file to install the new drivers.

If this doesn't solve the problem, then please provide us with the information in this post: http://www.techsupportforum.com/1871981-post2.html

Just FYI, here's my blog post on analyzing these files: http://usasma.vox.com/library/post/d...d-02oct08.html
You'll notice in paragraph G that there are some additional commands, try them to see what you get.
Also, there's a link at the bottom to a general description of how to analyze the debugger's output.
