Black screen during boot up - Compaq Elite 8300 CMT - EPROM issue

[Jaguaar]

My Compaq Elite 8300 CMT either boots fine (2-4 times out of 10) or boots to a black screen with nothing ever visible. The CPU fans speeds up like that of a jet plane - the classic signs of the good old issue this model has. I saw a video in which it was concluded that it is due to faulty eprom chip that needs to be re-printed.

Anyways, my machine is being used for a lab and not for surfing etc. So if I put it to sleep, it wakes up fine, The problem comes up only when I restart or boot it. 

My question is - if i leave the problem as it is, will it remain stable or will the problem become worse and must be fixed. I am setting up expensive lab on it that has cost me a pretty penny so don't want to  see my effort gone in a black hole (pun intended).

Any suggestions folks?

You seem to have a problem with a "mission-critical" computer. So, "doing nothing" will bite you in the mass, sooner or later.

I think that you should free software, such as Macrium Reflect, to make a "clone" of the disk-drive.

Then, find/purchase a new computer that is quite similar (same number and types of I/O ports, same type of processor -- AMD? Intel?), and so on. Start-up the computer, to install its copy of Windows, and be sure that Windows "activates" over the Internet.

Shutdown the computer,  remove the original disk-drive, and mount the "clone" into the computer.

Boot the computer. Windows 10 should adapt itself to the changed hardware, but should eventually boot-up.  Try the software that you installed on the older computer, to see if it still works. 

You probably will encounter a "Windows is not activated" message, when the cloned disk-drive is now being used in a different computer. Buying another Windows license is not expensive, compared to the "loss-of-use" pain when your old computer suddenly "dies".

Another possibility:

* buy a new computer

* install Windows

* Install the Oracle Virtual Machine software

* Use some free "hard-drive-to-VM" conversion software, to take your current computer's disk-drive, and make a Virtual Machine image

* launch the Oracle VM program

* launch the VM image of your current disk-drive

Now, you have the software from your original computer running as a "guest" operating system under the control of Oracle VM on brand-new hardware.
