Help Diagnose, Windows keeps deleting itself, Ubuntu works fine

I bought a used Lenovo x230 and upgraded with a brand new Samsung EVO 840 SSD 250GB and Crucial 8GB of ram on August 1st of this year (2014). The machine ran perfectly without a hitch for about 20 days straight.

I was running Windows 8.1 64bit. About 5 days ago, I was watching Netflix when all my applications started to disappeared and brought me to the log-on screen with no apps visible, no start bar, nothing but a blank log-on Screen. When I try to log back in, I got he User Profile has failed the Logon error.

I Googled on how to fix that issue. After trying to replace the user profile with a working one from my other pc, after trying to repair it, after trying to delete it, nothing seemed to work. I ended up formatting the SSD completely and reinstalling Windows about 32 times (no kidding). Each time I re-install windows, I would be able to use the PC for about 10-30 minutes before it restarts itself and gives me the User Profile has failed the logon error again and again.

I reformatted using every available method each time a fresh copy of Win8 was installed. I use a bootable USB, went thru command prompt, clean, and created a new primary partition but to no avail, the issue contiinues.

I tried to install Windows 7 and the same issue persists. I installed Ubuntu to run ClanAV antivirus but it did not find anything. Back in Windows OS again, I went into an administrator profile and was able to run internet explorer and downloaded every single antivirus program I can think of before the computer restarts again and it did not find any malware or virus.

The Anti-virus i have used are:

Trend Micro
Kaspersky
McAffee
Avast
ClamAV
and BitDefender

As of this point I thought it was a hardware issue with the SSD. I went back to bestbuy and exchanged it for ANOTHER brand new one, same model. On this new drive, instead of the User Profile error, my windows partition would just keep deleting itself. The computer would restart itself, and then it says no OS found.

In Bios, the SSD is listed, in command prompt the disk exist but there is no partition. I remake a new clean partition a few time using NTFS file system and the problem is still happening. I re-installed windows 7, then 8 a few more times but it keeps restarting itself and losing the partition about 15-30 minutes of run-time.

I ran the Lenovo diagonostic via BIOS and it pass every test (Memory, Storage, Motherboard, etc...)

For the past 5 days, i've googled and tried hundreds of things and none of them seem to fix it.

Please help

Tyvm ill give it a try ill have to go buy an external CDROM unless I can use PW with USB.

The Sata controller is set to ACHI. Boot sector seemed clean according to the AV programs, also did a fix mbr, fix boot and rebuildbcd.

Unfortunately the laptop only has one SATA port
The drive letter is gone accordingly to command prompt boot from USB, but the disk is listed in diskpart.

This is the second brand new SSD I tried on this machine.

Layback Bear, I have the AVs listed. I'll post the rest when I get to work! Thanks for the help!

Already pulled the battery and turn on w/o it in. Sorry forgot to mention.

I dropped the laptop off to get it diagnosed for $35. Im almost certain they will not find an answer though. I will get the laptop back Friday.

I did my best to update the system's detail without running that .exe, I wouldn't be able to run it anyways because the Windows doesn't really exist lol.

When i get the laptop back i'll run the Partition Wizard on it like you guys suggested.

Regarding the clean install methods I used:

1) Used Windows 7 Bootable USB to wipe partitions and install.
2) Used Windows 8 Bootable USB to wipe partitions and install.
3) Used command prompt through the bootable USB, did diskpart, selected my disk, clean, format fs=ntfs, create primary partition, select partition 1, made it active, restart and used the USB bootable disk to install.
4) Repeated steps 1-3 on the brand new drive that I exchanged at best buy.
