I keep getting 'no input signal' while gaming.

[Orbital Føroysk 🪐]

I have no idea what is causing my screen to go "No input signal" and cutting the monitor off. I've tried taking the graphics card out and putting it back in, putting the RAM in and out, changing the monitor wire, buying a whole new PSU (750w) which is a great brand (Corsiar) and now I am out of ideas of what to do.
The only thing I can think of is the motherboard is ♥♥♥♥♥♥♥ bollocks or the monitor is dying. It never cuts off on the internet though. Only when I'm gaming.

Basically, I play certain video games and the screen cuts off and goes black saying "No Input Signal" for 5-8 seconds and then comes back on. The audio still works though. This happens on many of my games and my PC isn't even a bad build either so I'm assuming it is the motherboard and if it is, I really hate life because I just spent £65 on my new PSU which STILL hasn't fixed the problem!

Does anybody know what this could be and how to fix it?

Specs:
Processor: Intel Core i5 4670K @ 3.40GHz

Monitor: 17'' (1280x1024@75Hz)
Graphics Card: 2047MB NVIDIA GeForce GTX 660 (EVGA)

It could be a heat related issue if its only happening in games, if the gpu doesn't respond within a given time frame then windows will force a gpu reset. When that happens the screen will go blank for a couple of seconds until the gpu refreshes and redraws the frame. Check the temps on both cpu and gpu. maybe fans etc need cleaning.

I've cleaned the whole PC out from top to bottom of dust as well as the fans and the PSU is new. I only got it yesterday.

Did you install your PSU properly with fan facing the ventilation grill in the case floor and not up inside the case assuming you have bottom PSU mounted case?

Goto start and right click on my computer and choose manage.
select "event viewer/windows logs" and check applications and system lists for errors and post any errors related to monitor here. It may tell whats going on.

I'm on it but I'm lost at "check applications and system lists for errors". :P

Yes, it is installed properly. I got my friend who builds PC's to put it in.

Start > Control Panel > Power Options

Set this to 'High performance' if not already and then go into it's 'Change plan settings'

Turn off the display: Never
Put the computer to sleep: Never

Then click 'Change advanced power settings'

Under PCI Express > Link State Power Management > Settings
Set that to 'OFF' and click OK > Save Changes

If your fine with BIOS, reboot the pc and enter BIOS (press F2) and also check there for power management (mainly for your PCI Express - Link State) and disable it from sleeping. Also, disable your 'onboard Intel Graphics' if necessary.

Then ...

Start > Control Panel > Device Manager

Ensure 'Display Adapters' only shows one and is correctly your graphic card 'NVIDIA GeForce GTX 660'.

Ensure your 'Monitors' shows your monitor(s) correctly named.

If not correct, right-click and uninstall them. Prevent Windows from installing it's own. Download/install the latest monitor drivers and Nvidia software (such as Geforce Experience or just the correct drivers).

Also check all your motherboard drivers are installed and correctly working, no ? (unknown) or ! (conflict or errors) appearing under your device manager.

Then ...

Start > Control Panel > Display > Change Display Settings
Display should say the correct name of your monitor.
Resolution set to 'recommended' or native resolution of your monitor.

Under 'Advance Settings' > Monitor > Screen refresh rate
Tick the 'Hide modes that this monitor cannot display, then set to the highest available or default 60Hz > OK > OK.


This should cover most cases, if not hardware issues, if you wish I can explain each reason in more detail...

What are all those 'certain' video game resolutions set at? You will most likely find it's a resolution unsupported or a toggling issue with your monitor. Therefore the PCI-E Link State might be kicking in and putting your graphic card to sleep, resulting in that 'No input signal'. Ensure your running your monitor under it's correct native settings. Windows sometimes installs it's own crappy slow native drivers for it, so make sure it has the correct driver as well.

double click on "event viewer" then "windows logs" under that heading you will see applications logs, setup, security, system etc. Look at the application and system logs for errors related to your issue.

Thank you for the deep, detailed reply, but I have done all up until the last one and everything is set like that already and the names come up in the Device Manager, but the last one that says "Tick the 'High modes that this monitor cannot display" won't let me tick it. It is just greyed out... :/

Check to make sure your monitor / adapter drivers are correct, then reboot and check that again. Your connected the monitor to the graphic card and not onboard graphics right? The monitor and your pc chipset drivers are installed, as Generic Non-pnp Monitor might grey that out?

It does say "Generic Non-pnp Monitor" actually. Is that supposed to happen? I have no idea what make my monitor is. The latest driver for it was in 2006. It might just be my monitor that is the problem then. :/

[Azza ☠]

"Generic Non-pnp Monitor" is what annoying Microsoft Windows installs for default... it's a native driver designs for any monitor to at least work, barely, with limited resolution/refresh rates... but not the real drivers for it.

Look for your real drivers online at their offical site or via google 'Monitor model name/number drivers'. Even if it's 2006, it will most likely be better - it understand how your monitor works, the graphic card should take care of the rest so long it's not buggy or incompatible.

Start > Control Panel > Device Manager
Under the Monitors tab, right-click it and either uninstall (then cancel any driver found by Windows icon on your taskbar) or update (and select just manual).

Install the real monitor drivers and reboot. You will find it will start working a lot better in most cases and might be your issue.

Make sure the Graphics Card (GPU) drivers are up to date, as some games could have issue if they are old.

In Device Manager, right click what is listed for Display/Monitor and Remove/Uninstall that. If it does not ask (it should) after doing this, please restart Windows. Then see what it automatically detects as your monitor. Even some name brand ones will come up as "Generic Monitor" which is quite normal.

If you are using VGA, try a different cable connection if possible, like DVI or HDMI.

[Orbital Føroysk 🪐]

Ok, so I borrowed a new monitor and it still happens. I don't know how to get rid of the Generic PnP Monitor thing either and install this monitors driver. I don't know what monitor it is though.

I also un-installed and re-installed the Nvidea Drivers and that's done nothing for me. I'm out of ideas on what it could be. I'm really considering just getting a PS4.

> Try a different NVIDIA driver version, newer 335 version has many issues, try older one ranging from 331 - 334. First download driver u wish to try, then uninstall current ones, reboot when asked. During install of drivers, select custom, then select the clean install option. To see a list of many driver versions, use GeForce.com instead of NVIDIA.com


> Generic PnP Monitor is normal, doesn't need any special drivers.

> Monitor the CPU & GPU temps. Too high and the GPU could go into a failed state, in which the driver may reset in order to prevent entire system lockup. If the OS is saying "Driver has failed" down in taskbar, usually a driver that doesn't work well with your particular GPU, or the temps are getting too high.

ive never heard of 666mhz for the ram that seems low. ive seen 1066mhz. if your ram is unlocked go into your bios and turn it up to where it is suppost to be. idont know if thats your problme just somthing i noticed

[Bad 💀 Motha]

666-668 roughly is correct for 1333 RAM
i.e; 667x2=1333 (not exact, but the motherboard/bios rounds it off)

So for example, in BIOS u should see 1333 for DRAM
But in the OS it might show as 667 (again, both are correct)
