Yes, hardware problem and an older (but valuable) system.  Possibly the bios got corrupted.  It is also possible some other device or software is contributing to the problem.

I assume this is not your system as it was imposed on you.  Two of my kids are Mac believers like you but they are allowed to be imposed on for windows gaming.  When they ask me for advice on their Macs I tell them to get a Window system.

I have had several Z400, all windows 10 and at one time I had a pair of GTX-1070 but there was a cooling problem so only one GTX now.  You will not have that problem as your graphic boards take up on a single slot.  I take it you are limited as to upgrading as it is not your system.

Was this system working OK at any time you had it?  If so, was there a power outage or some event that might have happened?

Please look in the windows Event Viewer.  Look in both SYSTEM and APP for anything suspicious.  To make it easier to find the problem, delete all the logs and then reboot.  When the system comes up the logs will show only the most recent events.  Also, can you check the device manager for any yellow or red flags?  If so post the picture of detail what driver has a problem, if any.

Can you download CPU-z and post the image of the MAINBOARD dialog box like below from my Z400?

I am curious  what your bios revision is and can look up bios problems that might give a clue.

@testhis --  

just lose the BIOS config every time it is shutdown.

I have read this non sense other board where people are ask to change the DC or the board.

This won't happen

I know it come from the Bios doing something that can surely be fix either by some sort of reset.

I would not be able to use the computer with 4 monitors etc if there was any physical hardware problem.

I am a MAC  person trying a PC for the first time really, and I have never ever wasted my time like I do now.

Never did I had to spend a minute to fix an Apple machine ever.

I am using a PC because I am impose so.

But this board will be my only request.

If I cannot fix this I gone from PC forever.

I won't spend my day fixing ridiculous problem when they should be fix in a minutes.

So before coming with non sense change you board stuf think twice

I have been trying for 5 days now and I am not spending anothe day trying to figure out this.

For any Apple or PC computer, there is a battery on the motherboard, about the size of a US $0.25 coin, with a silver-coloured top, with some engraving on the top.  

What has happened to you is that battery is not providing any power to the motherboard, causing the motherboard to lose all the settings, including date/time, after your power-off your computer.

If you are comfortable with working "inside" your PC's case, do the following instructions.

If you are not comfortable, take your computer to any computer technician, with a copy of this reply.

INSTRUCTIONS:

Open the computer's case, and gently remove that battery, and look at the engraving.

Maybe, it is "CR2032" or something similar.

Take the battery to any computer-store, and show the battery to them.

For less than $5, purchase a replacement battery.

Push it into the socket, with the engraving visible on the top of the battery.

Power-on your computer, and set the date/time, for the FINAL time.

Done.

As @itsmyname suggested, it is possible the battery is in upside down and that is easy to do.

The engraving should always be on top.  Look also for damage to the socket that prevents the connection from being made.

Hi,

At least now I am able to prevent the time and date problem. I went into the bios yesterday but did not try to boot until this moring. The boot order was USB first yesterday. Change it ti drive. Booting this moring did require to unplug everything but did not require to save new hardware detected by pressing F1 to save it restart get F10 into bios to change time and date.  So this seems to be fix now. So, all I had to do today is unplug everything replug cables,  press power and it did boot. So now, what is left to figure out is why do I have to unplug everything. It might be one of the hardware link to a specific cable like a display port of on of the graphic card or it maybe the usb moshi 2.0 hub plug into a rear usb. I'll try to figure out which one may be the cause. I bet it is the second graphic quadro card... Will keep update when more info

There no event really specific other than  kernel event tracing ID 3 which was link to a security

and a ID 46 VolMGr crash dump initialization failed which maybe the reason the intial boot crash 5 red beep. Maybe because of this error but I am not a windows guy yet so...Weither it is link to the initial boot or not I cannot tell but If I can fix this error I guess it would fix the problem

The error ID 46 VolMgr is related to the paging file not being set up properly according to Microsoft support who say to ignor eit.

The only thing I can think of is possibly you do not have enough disk space OR MAYBE the hard drive has an error and the paging file cannot be loaded on restart. 

You should maintain not more than %85 used space on your hard drive.   Please download and run speedfan and run the disk drive SMART test to check for errors that windows 7 does not always check for.

If there is a problem with the paging file it is difficult to fix as it requires booting in safe mode and getting permission to rename or delete it.  If there is a problem with the disk please post back here for assistance.

[edit] Clarified the % space used
