I hath replaced the motherboard within mine computing device, forsooth, as the former did suffer from a lamentable malady of broken CPU pins. Initially, the apparatus didst function with fleeting splendor, only to be ensnared by the ominous Blue Screen of Death after but a brief interlude. Thereafter, it refused to rekindle its luminance; the screen lay shrouded in darkness, while lights numbered one and two did pulsate in a most disconcerting manner.

In my earnest endeavor to rectify this technological travesty, I sought to reset the BIOS. Alas, the slot housing the battery suffered a dire misfortune, rendering my attempts futile. Regrettably, the quandary persists, and I express my sincere apologies for the fractured eloquence, for I have relied upon the aid of a translator, as English stands not as my native tongue.

Sorry but you have post on a tech forum asking for help but have provided zero information about your computer or it`s hardware, this makes it impossible for anyone to even hazard a guess as to what is going on.

Is the computer a custom build or brand name such as Dell or HP, if a brand name provide the model name or series number (not serial) if a custom build post the brand and model name or number for the following:

OS
CPU
Motherboard
RAM (including the amount and Number of Sticks)
Add on Video Card if one is used
Power Supply Unit

Providing these details will enable folk to better help you.


So other can assist let get a speccy report.

Do not forget to post the make and model of the PSU if this is a desktop.

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.

To publish a Speccy profile to the Web:

In Speccy, click File, and then click Publish Snapshot.

In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.

Speccy publishes the profile and displays a second Publish Snapshot. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.


Let's see if there are any error message that can be pulled by the MinitoolBox.

Download MiniToolBox and save the file to the Desktop. Right click on the file and select Run as Admin

Close the browser and run the tool, check the following options.

Select all

Click on Go.

copy and paste the contents of the file called MTB.txt or attach the file to your next post.

The PSU is the WAY under for the GPU that you have.

GeForce GTX 660 | Specifications | GeForce

Check out the latest NVIDIA GeForce technology specifications, system requirements, and more.
www.nvidia.com

Requires a minimal of 400 Wats the PSU that you have can maybe on a good day produce 204 Watts. Before that you burn out the GPU or something else get the PSU replaced with a proper one.

support.lumion.com

Which power supply do you need?

1. Power supply requirements for desktop PCs Note that the following only applies to desktop PCs. Power supplies for laptop PCs are always designed with the correct Wattage. The power supply is a v...
support.lumion.com support.lumion.com

Since the CPU has the onboard graphics suggest that you use those till then and remove the GPU.

Granted it states 250 watts the rails can only produce 213 watts.

12 * 17.8=213

It operated smoothly for an extended period, and it performed flawlessly without encountering any issues whatsoever

No point in this thread remaining open when the guidance offered is dismissed by the OP :(

You can always go and pay a local tech who will only tell you the same thing.

Fwiw, the OPs video card wasn't even around when the computer was released which means that it has been added afterwards, further proof that the junk PSU is no good for the GPU.
