Computer is shutting down randomly

I would probably go for a better gpu. Dont know

Did you sa a DR in the Caribbean? What's your electricity like? Any power outages or brownouts? You might need to run from a good UPS like UPC or Tripp.
Any power spikes? You might need a line conditioner, also from UPC or Tripp.

Even mini brownouts and mini spikes can damage electronics, so I've heard. Wondering if this is your issue. Investigate before you buy something since these are not cheap, and batteries need to be replaced every two years.

No need to re-install programs, you can just use your existing windows boot drive on the new machine. Just follow the instructions in this post I made a while back, plus follow the steps in "Scenario 1" that is a part of the referenced wintips link. You do this right before your very last shutdown on the old machine, just prior to moving the boot drive over to a new machine.

Remember my machine will not boot up, so no drivers can be downloaded from the old machine, ...

do you know any other way ... Have you done it with Acronis Universal?

Thanks

if your machine will not boot, that means you will need to employ Scenario 2 instead of Scenario 1 in order to prepare your boot drive

and since you cannot download the drivers ahead of time, you can just load them using the DVD that comes with the motherboard if you have a spare DVD drive somewhere, or if you have no DVD drive, you can download them using a different computer onto a USB drive, then put that USB drive into one of the black USB ports on the new motherboard and load the drivers that way. The black USB ports are USB 2.0 so they will not need special drivers, but your USB 3.1 ports will not work until they have drivers installed. Also note - Once you prep your hard drive using the Scenario 2 steps, then boot to the desktop, its possible that your ethernet port will work automatically. If so, you can skip the USB and just download your drivers from the motherboard site.
