UBUNTU 14.04 restarts system about 10 seconds on desktop

If you log in as a different user is it ok (make a new user if needed)

System ran fine on Ubuntu 13.10 for over 6 months
Memory : 7.2 GB
Processor : AMD A8-5500 APU with Radeon(tm) HD Graphics × 4
Graphics : VESA: DVST
OS type : 64bit
Disk : 110.1 GB

No proprietary drivers are in use

Please answer #1. It is a troubleshooting tool, that will give Actionparsnip the direction, he will go.

No , if I log in as a guest or even a newly created user it does the same thing, the only way I can stop the continuous restarting is to ctrl alt del and select adv user options/ recovery, but after the next restart the madness continues.

Upon restarting in recovery mode, I caught a glimpse of what I believe to have been "FAILED SMB/Active directory server", what does that mean?

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Memory test passes with no errors, I disconected all drives other than O.S. solid state drive, disconnected all other accessories, keyboard, mouse, speakers, ethernet, everything one by one and restarted each time, with only ram and O.S. drive connected it still exhibits the same problem(continuous restart), it does appear to change the display resolution when restarting but no matter which resolution it sets, the results are the same, when starting in the safe graphics mode the results are the same.

No proprietary drivers are in use. I can not even do a clean install because (it does the same thing when booting from a usb pen drive), isn't it strange that it has the same bug when booting from a freshly created boot ISO. with no other hardware connected and the memory passing full mem test without any errors, it really looks like some kind of hardware incompatibility bug with either my APU or SSD, the same newly created bootable pen drive works flawlessly on other computers.
I did notice that if I play a youtube video when it boots, that will stop the system from restarting continuously..... any suggestions?

This is definitely a bug, I don't know if it's the mainboard (MSI FM2-A75IA-E53), SSD(SAMSUNG 840 EVO MZ-7TE120BW 2.5" 120GB SATA III TLC Internal Solid State Drive), or APU (AMD A8-5500 APU with Radeon(tm) HD Graphics × 4 - Gallium 0.4 on AMD ARUBA ) (64-bit O.S.) that's causing it.
Once I realized that simply playing video would circumvent this bug, I then looked for a way to implement a screen saver at startup, I came up with XWINWRAP / GWINWRAP.
I installed XWINWRAP in terminal mode, then GWINWRAP and set it with a screensaver to run on startup, of course the screen saver stops as soon as you move the mouse, so it really has no ill effects and solves my problem while implementing a screensaver.

This system ran perfectly without any issues on 13.10, the hardware has not changed and 14.04 trusty is not even compatible from a clean install because of this bug..., revert back to 13.10 and all is well, upgrade or attempt 14.04 trusty clean install and nothing works....
