Hello, 

 

I had a fairly high end custom system made in Hong Kong and it worked great for about 2 years.....after that period I would start getting either get black horizontal lines across the screen, or tiny spotty white dots and then the display would go completely blank. I had initially diagnosed a problem with the HDMI connection from the graphics card as it was loose, replaced the cable, worked a little bit longer then finally quit all together. I replaced the graphics card with an all new Nvidia GTX960 card and the computer worked perfectly again for about 3 weeks, and now the exact same problem occurring again....im getting about 2 hours of use time before the display starts checking out.  

 

I don't think it is the screen, as it does similar stuff when plugged into other display units.....my initial thoughts now are cooling problems, however I was hoping for some better opinions prior to investing in upgrades. Thanks for your help 

 

 

Processor AMD Phenom II x6 1055T 2.8 ghz 

RAM- 2 4GB CL9 Transcend 

Graphics- Nvidia GTX960

Power- Enhance ENP600 (600watt)

Motherboard- ASUS M6 A97 PRO

So I've managed to catch a quick iPhone video of the fault. Last night I opened up the case, did some dusting and re-seated the graphics card. This morning I got about 4 good hours of gaming in, did a full shut down of the computer, went to the gym, and 2 hours later came back, switched it on and the fault started immediately

Thanks for the update 

 

Power- Enhance ENP600 (600watt)

 

 

Not finding any such PSU among my power supply archives, can you open the case and see if it is labelled as something like ENP5160 or ATX 1360, both of these are 600W PSUs, if no info is available let us know how long you have had the PSU.

 

Nothing in the video that would suggest a bad power supply or high temps but we will check them out first in any event, see below;

 

Download Speedfan and install it.  Once it's installed, run the program and post here the information it shows.  The information I want you to post is the stuff that is circled in the example picture I have attached.

If you are running on a vista machine, please go to where you installed the program and run the program as administrator.

 (this is a screenshot from a vista machine)

 

 Download then run HWMonitor and post a screenshot so that we have a comparison to the Speedfan results, details from here

 

To capture and post a screenshot;

 

Click on the ALT key + PRT SCR key..its on the top row..right hand side..now click on start...all programs...accessories...paint....left click in the white area ...press CTRL + V...click on file...click on save...save it to your desktop...name it something related to the screen your capturing... BE SURE TO SAVE IT AS A .JPG ...otherwise it may be to big to upload... then after typing in any response you have... click on browse...desktop...find the screenshot..select it and click on the upload button...then on the lower left...after it says upload successful...click on add reply like you normally would.

 

Screenshot instructions are provided to assist those that may read this topic but are not yet aware of the “how to”.

 

Can you continue to use the edit tab if you have something to add while waiting for a reply, this ensures that nothing that you post gets overlooked, something that can happen if a thread has more than one page.

 

You are welcome btw  :)

Thanks phillpower2,

 

I will download that Speedfan app to take a look at the internal temps....I have been on the road for work quite a lot the past few weeks and haven't had a chance to yet.

It did occur to me that when I tried to use a different monitor to the same effects previously, it was with my old/defective graphics card. I had some time the other day and set the desktop up on a different monitor and didn't experience any of the previous issues as before, so I will continue to try that out and then it may just be a simple case of a burnt out monitor.

 

Will advise further,

Cheers

Aye I perhaps should have confirmed whether or not both video cards had been tested on other screens and gotten the same results  :( 

 

If you still have the previous video card it would be worth testing to see if works ok, if it does you may be able to sell it on to recoup some of your outlay for the new card.
