Crashed!

My own computer has crashed. Writing this on DH Dan's. No blue screen or anything, just bam! gone, everything. If my house burned down & I lost everything I own I couldn't be more bereft. Looks like I'm going to be incommunicado for awhile. The SOB started once & I tried "system restore," but it froze during the restore and has not started since. Excuse me, but I have to get back to my sulk.
