no input signal - twice in three months, my monitor has gone black.
today i was browsing. my pc had been on for many hours. suddenly the screen went black, and the notification from the monitor said no input signal.

i remembered this had happened once before, maybe three months ago.

i checked my dp cable was attached. it was attached on both times this happened. pulling out the cable and plugging it back in did not fix it. pc would not wake up with a mouse nudge.

the only way to get it back working was force a power down with the pc power button. then restart.


it could be a windows 10 issue. or more likely a gpu driver issue. .... the nvidia forums have nothing recent about this. very old threads did discuss this happening.

i figured run it past everyone, to see if anyone else got this, or had heard of it recently.

specs:
8700k
1080 ti
32gb ram
asus z-370 tuf pro gaming motherboard
corasir hx750i (psu).
have added psu to above post. (i added specs because i knew someone would ask. however i think it's a software issue.)

unlikely that it's the psu.

the current psu is a hx750i, and the previous psu was a hx650i. swapped over a year ago at least. this is a recent issue.


good, a lot of times this is the psu. but with an excellent unit, that's far less likely.

were you monitoring temperatures at the time? was there something specific you were doing similar in both times? really intermittent things can be hard to nail down.
thanks, to all of you for the replies, after much trial and error turns out the culprit was the PSU. Amazingly one of the modular plugs had a dead terminal and was not giving power thru the cord, I tried another one of them and boom, GPU read. Seems like GPU was receiving only half the power it needed to fully be operative. With one plug it did turn on and fan blew but it was not functional until the second plug gave the rest of the power. Rediculous lol Thanks all who replied, never even thought of trying another terminal until i started trying to do stupid random things. Now to send back this damn PSU lol

hence we are closing this topic. if need further support, please open a new one.

thanks

what’s the frame rate? have you try boost the system to performance mode to try? You can get seperate dc jacks from here

Try not to disconnect the screen as it may never come on again, i would take to a qualified repairer. > Hello. I have an HP Pavilion 4500 laptop and it won't turn on. I've tried everything to get it to turn back on. There are no flashes or beeps or anything when I hit the power button. Also, before all this came up, my charger wasn't charging correctly. It would turn on then turn off repeatedly. Then one day, my laptop shut off and didn't come back on anymore. I haven't been on my laptop in about 4-5 months now. Could someone please tell me what might be wrong with my laptop?

you havent used it in almost half a year!!!! get yourself a correct charging unit for it that works properly and charge it. leave it out in a warm spot for a day before hand though. it sounds like its gotten very cold internally and also all the battery power has seeped away to nothing. this happens with rechargable batteries after a while. of course you wont get anything when you've got a dead battery. sounds like the charger you have already may be defective or your current battery is defective at least.  

At the other end of the scale though it could be that you laptops power supply unit has become defective and maybe that has blown.  

Rule out the simplest options first of it being the charger or battery. if theres no joy take it down to a local computer engineer and get them to have a look. be prepared to spend a little dosh on it.



btw what r your laptop specs?? might help us.:D thank you for taking interest in my post.

i have solved the problem.it was mistake from my own part.

i have disabled some of the hardware detection services before the update.

i have disabled the "device install service" on the windows service

renabling it and rebooting it solved the … that is where i'd start as well. osi...
so:
1. physical link (maybe check the patch panel and the cabling that's involved in connecting to the computer, maybe swap cables and try a usb to ethernet adapter to rules the nic out.
2. data link - check the switches and switchports on the way. maybe try to use different portts
3. network - most likely not an issue if all the other computers are working fine...
etc.
but this is pretty much it: Are you using drivers released by and/or approved by you laptop vendor? Or are you using later generic drivers from the Intel and Nvidia sites? If the latter, well, that's likely your problem. Go back and test again with drivers from your laptop vendor.

[View solution in original post](/t5/Graphics/Problem-with-Intel-UHD-Graphics-630/m-p/1227288#M91445) hi so i did a full clean reinstall of windows 10 and now it works again. must have been a settings or some software that did not work well with spotify or sonos connect app or could have been drivers of some sort. thank you annazel s for giving me tips and helping me out even tough i was so slow replying to you. a quick fix is to go into the "device manager" Start-settings-control panel-system-device manager and right click on your keyboard and select delete. when it's deleted restart your pc. You will not be able to use your keyboard until it is reinstalled by your computer let it start up and you will see a little come up that wil say something like found new hardware or found new keyboard. after this you should be able to use as you used to Hello ramavtar..
