Hi Ahmed,

Since you mentioned your system shuts down after parts replacement, I would suggest you to ensure that the processor fan is connected properly as it is the most common reason for this issue.

Also, check if the issue persists in safe mode. Restart the system and tap F8 key for advance boot options. Highlight Safe Mode with networking and hit enter.

If the system does not shut down in safe mode, you may perform clean boot to troubleshoot the issue. Refer to Microsoft KB Article 331796 using the link mentioned below:

Please keep me posted with the results.

Thanks & Regards

This was before I replace all parts
I practically built a new system so I wouldn't have to deal with fixing the problem now I feel it's haunting me

Are all the fans running and did you apply the CPU thermal paste in the manner recommended for that processor when fitting it onto the new motherboard?

Always pop back and let us know the outcome - thanks

Hi Ahmed,

If you are not using any component from the old system and system still turn off randomly, please check the power socket as it may be the cause of the issue.

Did you reinstall Windows? This is required if you change the motherboard. If an OEM install of Windows, you will need a new copy with a new install key.
Did you test the hard drive with the mfg's test utility? The problem could have been a bad hard drive from the beginning. Run the longest test in the suite.
Is it the same power supply? A bad power supply could also cause the issue if the voltages are not within 5% of their nominal values or the amperage on one of the rails is not sufficient for your system (cheap, incorrectly rated, undersized, or just going bad).

You have to be a little bit crazy to keep you from going insane.

When I replaced the old motherboard, cpu, psu and memory I reinstall windows and everythings seemed fine for a day and until it happened again. I changed the hard drive and installed windows and the same thing happened. The only parts I didnt replace was the case and DVD drive. I find it strange that sometimes it automatically logs off windows and then shuts down even if I'm using the computer whereas other times it just goes off.

Sounds like you may have hardware compatibility issues.

Are you overclocking the CPU?

Do the RAM specs fall within the accepted range the motherboard supports?

If using multiple RAM chips, are they matched pairs?

Some, if not most, motherboards require multiple power connectors connected at different points to power on correctly/fully. Are those connections correct and secure?

Are you using a PCIe graphics card, or the motherboard's on-board video? If using PCIe, does its specs match what the motherboard supports.

List makes and model numbers of all components, especially power supply.
Did you test the hard drive as I asked above?
Boot into BIOS and leave it run that way for quite a while. If it freezes or restarts in BIOS, it is not in the hard drive, but some component (or proper application of thermal compound between CPU and heat sink). If it does not restart in BIOS, but just in Windows, it is driver or other software issue.
If it is stable in BIOS, restart in Safe Mode and let it run there for quite a while. If it restarts, it is a hard drive or windows/installation issue. If it does not restart in Safe Mode, then it probably is a driver issue.
If it stay stable in BIOS, then run the hard drive utility from your hard drive mfg or Seatools from Seagate from a bootable CD (DOS version, download ISO image and burn CD, then boot to it.
It would also be a good idea to try Memtest from a bootable CD as well, in fact, I prefer to usually run it before the hard drive test since bad memory can lead you to many random false hard drive errors during the test, even if the drive is perfect.

You have to be a little bit crazy to keep you from going insane.

Im not overclocking the CPU,I'm using 1 stick 4BG ram is accepted by motherboard, I have onboard graphics. Please keep in mind I had this same problem with my Packard Bell iMedia PT.U05-PV.U05 first before I upgraded.

"I had this same problem with my Packard Bell iMedia"

It might just be coincidence - sometimes this happens.

Always pop back and let us know the outcome - thanks
