Asus ET2400XVT keeps displaying no signal when playing games

[TVIRUS]

Hello all,

I have an Asus Et2400xvt PC an whenever I play games, it crashes. The sound cuts off and the screen turns black displaying no signal. I have tried to fix this but so far over a period of 2 years, I came to no solution. My suspect is my 240W PSU or my graphics card (GTX 460m). I have read over forums and FAQs but I have came out clueless. I have even asked my friends yet even they couldn't work out what was the culprit. Please help me...

Has it always done this?
When was the last time you blew out the computer with a can of compressed air, overheating can cause issues like this. Pet hair and dust can clog up a computer pretty fast.

Also update graphic and sound drivers if they have not been updated in a while. The latest drivers for that computer on Asus' website are from 2011 so those are pretty much useless.

Try these,

Thanks for the reply and yeah it has always been like this. I recently downloaded RealTemp and it displays around 80 degrees Celsius while playing graphics intensive games like Skyrim and 50-70 when playing normal games like Fable, Divinity 2 and KoA. The base temp is around 50-60 degrees Celsius after I stop playing games and 40 degrees Celsius at idle when I start my PC . But, somehow all games no matter how graphics intensive they are, manages to crash the monitor and cut off the sound (unless if I'm wearing headphones) but my PC fans go louder and my PC remains on until I force shut down. Not long ago, a nice guy helped me replace my HDD drive to a 256GB SSD as a gift also cleaning all the dust in the process. So I don't think my temp is the problem or my drivers. Any ideas??? Ty

80C for that CPU is a bit high (100C is max) but should really not cause problems like that. My thinking is it is the graphics driver causing the issue, it may have been corrupted a bit and if you have never updated it it is very very old and will not give you the best performance in games anyways.

Did you try the new drivers I linked, Graphics and audio drivers? If not do so as those wil give you the latest drivers, both audio and graphics.
It did this even when it was brand new and you got it? Why did you not return it under warranty at that time and get a new one or at least get it repaired under warranty?

It could possibly be the graphics chip over heating as well but you'd need to install a program like speccy or MSI afterburner. MSI Afterburner is a little bit tricky to set up at first but you can monitor your CPU and GPU temps in real time in a on screen display (OSD) as you are gaming.

I don't think that was the solution. I tried updating my drivers and after that, I still got the same recurring problem. That nice guy I was talking about said not to update my drivers for my 460m because manufacturers like Nvidia may unintentionally create flaws when they release new drivers (it didn't work anyway). Do you think it has something to do with the monitor or the cables linking it? Because I tried a graphics card stress test (OCT program) and for some reason it didn't crash. The temperatures were around 70 degrees Celsius. So I don't think an overheating GPU or the outdated drivers are the culprits. Also, the warranty for it is kind of broken. The small waranty handbook said that the warranty can only be used if you have made absolutely no changes to the PC and that includes the HDD drive which was replaced. That also includes all the software which I downloaded. I only realized what a troll Asus was when I began playing Skyrim thus means a voided warranty. No turning back now.

Hmm it may be a bad monitor cable but would not think so since both sound and video goes out unless that is one of the monitors with speakers built in and you are using those.

Usually new drivers work pretty well sometimes they goof some up but it is rare. Best bet is to just look for a driver that is one or two back in release that way people have tested them out and confirmed they work. But having said that I usually do not have any troubles with the newest graphics drivers.
But yea the graphics passing OCT stress test makes that less likely of a suspect although the driver could still be crashing but usually a pop up occurs when that happens stating display driver crashed and recovered.
One thing you can do is go into event viewer and look in the windows logs under application and system and see if any errors are turning up in there at the time your computer has the problem.

I am not too bright with monitors but I studied a little and I found that some cables may be unable to withstand the Hz of my monitor. I also tried error reporting to Microsoft but somehow, my PC fails to record the error at the time when my monitor and speakers cut off. Is there anyway to make sure that it records the error? Also, the GeForce experience program seems to have deleted itself making it a lot harder update any drivers and also harder for me to know what's actually in the update. The sound I think may also be an area of concern. I have 3 sound drivers/programs/software or whatever they're called. Asus SonicMaster, Realtek and Nvidia. Do you think that this would be a problem?

The Nvidia audio driver will only be used if you hook up a TV via HDMI cable, The realtek audio is main audio driver based on your chipset. I suspect the Asus Sonic master is probably Asus' attempt at giving you a audio mixer or equalizer. Seems it also is "SonicMaster Technology also replicates the experience of listening to a surround sound system and has a volume range that is wider than regular all-in-one PCs". Having all three should not be a problem as Asus links a realtek audio driver in their supprt anyways. Each thing serves it's purpose. I tried finding some updated sonicmaster software/driver of any type but could not.

Now as far as the monitor I see that is a 3D monitor so I'd have to look into if a special cable is needed as I do not know much about 3D monitors. Let me ask this first, that being a all-in-one computer is there a monitor cable you can actually see or is it hidden or built in as I suspect.

One other thing I woke up with in mind this morning is it may well be memory going bad, and the only time enough memory is being used to use that bad section is when you are gaming. I'm going to suggest running windows 7's built in memory diagnostics, you should be able to find that via windows search on your computer. Just folow the directions it wil probably ask you to reboot your computer before it will start the memory test.

Did you look in event viewer for anything? About the only thing like you are talking about as far as recording/seeing the error would have to do with bluescreening and it does not seem your computer is actually doing that from what you describe but you can turn it on to pause on bluescreen if you want.
To do that click the windows start icon, right click on my computer, choose properties. On the left click on advanced system settings. On that click on settings under startup and recovery. In that window uncheck the automatically restart. Exit out of all those windows by clicking OK.

That will make it so if you do get a bluescreen, windows will pause and show the info that you can write down instead of just automatically rebooting.
