Craziest problem ever.. -W764 install

Hi,
I am new to the forum and greatly appreciate any help. In my life I have set up dozens of all kind of Windows version but the following has never happened to me before. Ever heard of this thing?
I have a HP 5320m notebook, that came with a normal HDD and W764 Pro. I wanted a SSD and bought the same OCZ Vertex 2, 120G that I use for my desktop. I made a new install with the DVD of the OS that came with the notebook. Everything worked fine until a couple of days ago. When I shut down the computer, the next startup would show the "not shut down properly" screen and the option with safe mode and everything, but booting afterwards is easy. But the crazy thing is that all files or settings are lost, when you have an improper shut-down, directories that I had created on the desktop, had just vanished. The problem does not exist when you do a direct "restart" from the Shut-Down menu.
Well I tried a system restore to an earlier point and I got some strange error about the antivirus program. Anyway the restore worked in Safe-mode and everything was good again. Well, after a few days it appeared again so I suspected it must be an update that I had installed.
I became tired and started a new clean install from DVD. Started Installation from USB-DVD, deleted all drives, combined and formatted it (quick, as supposed for SSD) and installed the W7 again. Worked fine. Then I shut the PC down, and started it up again. Guess what... yes the "not shut down properly" screen came again. I was pissed, but only for 4 seconds. Because after those, I was puzzled. The computer started up to my OLD system. Everything was there, all files, all settings, even the Desktop background, the password for the WLAN. It was like I had never performed a clean install...
Isn't this crazy? Any ideas? In a way I suspect the SSD to be the problem, but still have no explanation to what happened.
Thanks if you have read till the end and you deserve a good laugh... If you have any idea, i appreciate it very much.
cheers,
Chris

Did you use a Win7 installation DVD to clean reinstall without all the HP factory bloatware and useless utilities that have better versions built into Win7? Or was it an HP Recovery DVD that loaded all the lard back in?

If so, you'd do better to find a clean copy Win7 installation DVD for your version, or find any other retail version and unlock all versions to reinstall yours with Product Key from COA sticker on machine. Here I lay out how to do this for a purrfect clean reinstall without factory bloatware: re-install windows 7

Until then I'd try reinstalling recovery DVD but use MS Security Essentials with Win7 firewall. Here are also ways to clean up factory bloatware until you can clean reinstall: HP laptop has used up all four primary partitions
