Windows 7: Display shuts off, lost signal, widows freezes, tower stays running.

Display shuts off, lost signal, windows freezes, tower stays running.

My display shuts off, lost signal, windows freezes, tower stays running without a hiccup.My display or displays shut off and windows freezes when playing games. It started with Fps game loading inside of a window the size of the screen instead of full screen. I then tried playing another graphically demanding game with the settings maxed and the display shut off after several minutes of gameplay. Over time it gradually got worse and worse until it would shut off the display as soon as it loaded windows. I thoroughly cleaned the entire case and components, cleaned and recovered the system back a couple years and I got a full week of Gaming on maxed out settings without issue. Repeating the same steps didn't yield the same results and the display shuts off. At around certain points every time in certain games the display will lose signal. Its been like this for over a year and I think I narrowed it down to faulty drivers or overheating gpu. If it's faulty drivers, do I delete all present drivers and replace them with the newest? If it's a overheating gpu, do I take it apart and replace the thermal paste? Any suggestions? I maybe completely wrong?

Hello and welcome Atemup mate the GPU driver would be a good start Drivers | GeForce it is the latest driver and did wonders for my three desktops.

You could also check this
UsingHW Info PSU

Download HW Info and pick the right bit version -
HWiNFO, HWiNFO32/64 - Download -(copyand paste this site into the search bar) If you do not need the runninginformation in the smaller right hand panel close it. In the left hand windowclick on the + for the individual device groupings and they will open out tothe various components.

Go on opening out further until you get to the device itself. click on it and it will highlight. In the right hand window there will be a very detailed description of that device as in brand, speeds model number etc etc These are very detailed and are just what is needed for searching for drivers etc.


To get the PSU volts you need to select the Sensor button circled in yellow in the pic for PSU testing do the same and scroll down the readout as in my pic to where it has Nuvoton = yours might be a different section name / title. Post back a pic of that please.

If you want a more definitive test see this
http://www.sevenforums.com/tutorials/301799-psu-test-dc-output-voltage.html but please only use a digital multimeter and not an analogue as they inject typically 9v into a circuit to test and into a 3.3v or 5v rail - not a good idea!!see the partial pic of the correct sort of meter in that tutorial. details if you scroll down that listing.


Now a good reference article is this
Voltage Rails - Power Supply 101: A Reference Of Specifications it will explain in detail what the voltages are and functions of the PSU/

I'm guessing you have reason to believe this May be a PSU problem?

Well I was starting with the PSU simply because it is the cause of moreproblems than some realize.

Your readouts are ok the 5v rail a tad low for my liking being only justabove the 5% minimum rail voltage. As the GPU runs off that rail means to me atleast it could have been an issue.

Now the driver for that GPU needs updating if you haven't done it is this - the latest I found it worked wonders with my GTX 650's
Drivers | GeForce (344.11)

But first try reseating the card into the slot and doing the same with the RAM sticks and all power leads.

I downloaded those drivers last night with a clean install. I'll try reseating today...

Ok mate sounds a good way to go and try this

SLOT CLEANING

Now as for the slots toclean them use a strip of old credit card about 1/2 inch wide nip the cornersoff one end - preferably round them offhold a piece of thin lint free clothover the end dab on some form of alcohol - iso propyl alcohol (what we swab theskin with before an injection) is good and GENTLYswipe along the slots.

This can also be done forthe GPU slot/s and do not forget to clean the contacts on the cards / stickseither.

It is an idea to clean thecontacts on the sticks / cards while you are at it but be VERY gentle whendoing this.

Do you think filthy slots is the culprit? It seems like something more precise to me, display only sometimes shutting down after a specific action.....

Well Atemup as I have just told someone else I am a firm believer in eliminating the simpler things first before diving into long and time consuming and tedious tests.

You are under no obligation to do anything I say as I have already suggested some things to check and it you want to wait I will keep on looking and maybe someone else might pick this thread up.

Just so you know I pick up a lot of threads that have been posted a while and have a heap of views but no answers and I feel some obligation as a senior member to anyone in that situation to have at least a go for them. I have seen threads go on for very long periods of time and having been there done that have some empathy for those folks
