Hi, So I updated my desktop on win. 10 all was ok, however whilst in the middle of using (Or watching actually) my desktop simply went into a standby mode. At the time I didn't need to use the keyboard or mouse. I took of the side cleaned the fans and after connecting all the leads back still had the same problem. The keyboard or mouse don't light up even though the fans turn on when I pressed the power button the desktop remains in standby. The windows beep doesn't sound and the screen remains black although the monitor is working (I checked when I had it disconnected) I have tried a wireless keyboard and mouse but still nothing helps it out of standbye. The blue light is dim but the red light that usually flashes when powering on doesn't show. I tried using a different set of leads checking for anything loose and even having the printer ect. Disconnected still nothing. I had it built for me 2 years ago but am unable to get to the person who built it. I spoke to him explaining what happened what I have don't blah blah to try and resolve the issue. However he can't offer me any help without seeing the desktop which is difficult at the moment. As this is the last resort to try for some advice as I have tried everything else barr dropping it out of the upstairs window l. ANYBODY?PLEASE?
We have the same limitations as the person who built this for you -- without being able to see it and access it, we have no way ourselves to get it working again.
Sorry for the bad news, but when a desktop does not even power on, you have few if any options for getting it working again on your own.
To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself. You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.
But if it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do.
You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it. And the problem with that is, while HP does do repair work of some sorts on PCs still under warranty, they generally do NOT do repair work on PCs out of warranty because they are not a general purpose repair facility. You would have to contact them in advance to see (1) if they are willing to work on it, and (2) if they will provide you any kind of repair cost estimate.
