Apps Crash Computer will not boot up

When I boot up my Dell Studio Windows 7 Home Premium I get this message
Windows Explorer has stopped working.
If I try to close the program it doesn't do anything...it's like it's in a loop.

. If I try to click on anything just get a blue circle likes it running. It does this in safe mode or normal. I'm the only user, so I can't see if it's just my profile.
Only thing I can do it ctrl alt del and go to task manager. I can end task for explorer but still can't get to anything.
Thanks

I make the dmp file and zipped.
When I try to upload it to you. I get this message

I'm not sure why it's giving you that error, but the problem is that the dump is way too big.

.zip attachment limit here: 8 MB

Your file: somewhere in the 50-100 MB range, most likely.

Upload the .zip file to Rapidshare.

Gause,
Create a minidump file;

WIN PAUSE/BREAK key combo | in the left-hand pane, click on Advanced System Settings | in the Advanced tab, in the Startup and Recovery section, click on the Settings button | in the System Failure section, under Write Debugging Information, select Small Memory Dump | OK your way out

WIN is the key with the wavy flag.

Notice that the dump will be in the c:\windows\minidump folder.

Now let's see if I can find that link for the preferred way of bundling up all the info the dump readers like.
