Question "Beep" error codes for Lenovo IdeaCentre 5-14IOB6 Desktop - Type 90RJ

[Night FM]

When I boot-up my PC, I get 2 beeps prior to it loading the OS. I'm assuming this is an error code, but I've been unable to locate a list of error codes for my Lenovo

IdeaCentre 5-14IOB6 Desktop - Type 90RJ.​

Can anyone point me in the right direction?

Thanks. Strangely it doesn't display a POST message, just the two beeps. I also tried to enter the BIOS by restarting the PC and pressing F1 multiple times, but I was unable to enter it. I also tried another method listed for the IdeaCentre, which is holding down the SHIFT key while restarting Windows, and it still wouldn't enter the BIOS.

It may not be F1 in your case:

It may not be F1 in your case:

Unfortunately, I tried every method listed (Pressing F2 and F12, using "Advanced Restart", and holding down the "SHIFT" key when restarting) and it won't access the BIOS.

When I do these methods, the computer seems to restart during bootup (since I hear the "two beeps" a second time"), but otherwise merely displays a black screen (with no Lenovo logo) and boots directly into Windows.

What types of video outputs (e.g., HDMI, VGA, etc.) does your computer support? Does it rely solely on integrated graphics? Which output is your monitor connected to?

If possible, I recommend testing a different output to see if it results in any changes.

It supports VGA and HDMI. Currently I'm using VGA.

I have a Radeon RX 580 graphics card as well as Intel integrated graphics.

I discovered that the "beep codes" were due to a disconnected fan. Oddly, I was unable to get into the BIOS or see the error message on bootup with my Radeon graphics card installed, but removing it allowed me to do so.
