Hello,
two days ago we had a blackout in our street for almost 2 hours. My Computer was on, but afterwards impossible to start again.
The Fans were running,but the screen keeps black. After a "lost" jumper replacement in default, i got this beep code:
2 long, 2 short, 1 long, repeated five times, although the last time without the fifth beep.
I found a lot of Beep Code explanations, but not this one, so please give me a hint!
I changed the video card, the power supply, the RAM etc. no recovery. I still hope for a corrupted BIOS or so, the motherboard would be the worst case....

@Ohle -- there are many "beep-codes" listed at: HP and Compaq Desktop PCs - BIOS Beep Codes | HP® Customer Support
Can you match your computer's "beeps" to anything on that web-page?

Thx for the suggestion,
if i recognize the first two beeps as a BIOS failure followed by the two short and a long one, it could be this:
Unable to initialize video or video card required but not installed, which would be a motherboard issue or a BIOS problem?
I tried also the Windows+B "trick" and a different video card, without any success.

@Ohle -- Unable to initialize video or video card required but not installed, which would be a motherboard issue or a BIOS problem?
As the message suggests, can you experimentally add-in a PCI-E video-card, which should "bypass" the integrated-video (and any problem with that circuitry) ?

The motherboard (Basswood) has no intergrated grpahics, but i tried a different video card, a RX580.
Meanwhile i am convinced that the motherboard is the faulty device, i can t prove it but the whole system is from 2017 and now it´s time to renew some parts of the PC.
Thank you for your suggestions!
