fans work. Screen does not work.

[william28126]

I have a all in one "HP ENVY 23 TouchSmart PC".

Fans work. Everything is normal, no beeping but the screen wont work / PC is on but nothing is displayed. 

How this problem occured:    I was shutting down my PC multiple times (I forgot why i was shutting it down but i did it like 20-25 times non-stop.) Then it was starting up slower then it usually did. Then when i tried to repower it from the shutdown, it powered on but the monitor does not display anything.  

Please help this computer was very expensive and i cant buy another one. But i do have enough money to buy  separate parts like motherboard, hardrive, ram and cpu.

I can replace stuff and i had classes before showing how so i dont have problems with new parts.

But the problem is that I dont know what is broken. Please help. 

Fans work, everthing works exept the screen. There is no beeping.

I tried to boot my computer after removing the harddrive still no beeping. Please help.

I have the same problem. My computer was bought in 2009 though, so I would expect the hardware to be dying of old age

Welcome to the HP Forums 🙂

I would like to take a moment and thank you for using this forum, it is a great place to find answers.

As I understand the fan works, however, the screen remains blank,

No worries as I'd love to help, however, I need a few more details to provide an accurate solution:

Have you attempted to tap on the F10 and access BIOS to check if there's a display? as that would confirm a hardware or software malfunction.

While I await your reply, here's what you could do to resolve your concern:

Attempt a BIOS recovery

If the above steps work and the display turns on: Perform a hardware test to be on a safer side.

If the steps didn't work, use the below links for further assistance:

I did try to access it earlier, but the computer kept crashing before I could do anything. Now it crashes after only a second. I believe it's hardware related, maybe the PSU? I'm taking it to a local PC tech wizard guy on Thursday, maybe he can spot the malfunctioning part.

Hi. I did some stuff you told me like pressing f10 after startup. But nothing happened. I did it like 5 times. After I examined the USB ports i figured out that they are all dead. Sooo when i press f10 nothing is happening because the ports are fried.  

The computer fans still work and the power cord works works but the usb ports and internet ports don't respond. What does this mean?

I tried to charge my iPhone and a Samsung and none of them were charging. 

There is a usb at the back that connects keyboard and mouse to PC and i took it and plugged it in a Chromebook it worked great. And i tried to connect other divides to my broken PC and the PC is ignoring all of them. Please tell me what this means? 

I cant do any bios things like f10 and f5 because my PC is ignoring the mouse, keyboard and other stuff.

Sorry if i wrote something wrong my English isn't that great.

My computer is now up and running again! Turns out the graphics card was dead. The tech support guy took it out and enabled the CPU's integrated graphics card thingy. It runs slower now, but since I'm soon buying a new one, it's fine. Thanks for your help!
