Frying DVI cables?

I have a weird problem that seems to keep coming up. The first time it happened I thought my video card went, I tried everything to fix it and ended up fixing it by making a mistake, as I had everything apart I grabbed another cable (VGA with DVI adapter) and hooked it up, then poof, I had an image. I bought a new DVI cable and it also worked fine. Now it has been a few months since I had this new cable and it just did the same thing to me. Out of no where the screen goes crazy and fragments really bad with black lines all over and then no image. I am now again running the same VGA with DVI adapter as last time. At first I thought it was just a bad cable, but now 2 in a row in the same way? Just seems a bit odd to me, anyone heard of something like this?

First cable was a cheap rosewill one (paid like 5 bucks for it?) second one I thought I would get something that cost more (maybe it would be better quality) and paid around 30 or so for it.
 
Have you tried going back to the old cables just to see if they are truly not working anymore. I find it incredibly hard to fry a cable with as low of a current draw that exists in DVI signalling.

I thought the exact same thing! If you look inside the cables I don't see HOW it could be fried by what is put out by the video card, and I would think the video card would fry LONG before the cord would.

And yes, the other cords do not work, even used them with another pc/mon setup to check.

No, if they had they would not have been alive to do it a second time. :D
 
Brand/Model of Monitor? My Westinghouse did that and it turned out the be the monitor.
So now I use my Hanns-G monitor which only has an HDMI port.

Also DVI and HDMI cables use really small wires inside and can be easily damaged. I had a belkin Pure AV DVi to HDMI cable that some of the wires got messed upside close to the DVI end (cable was cheap from work). I had to position it *just* right and it was fine.

Tight bends and such are hell on DVI and HDMI cables.
 
I managed to kill 2 DVI-HDMI cables while they had a signal passing thru, by spilling a glass of water. I was able to confirm their death due to having an excessive number of spares. Having just checked, they still don't work, weeks later.

Its a Westinghouse L1975NW. What do you mean it was the monitor?

The cables have some bends in them, but nothing major, at least nothing I think should cause anything to "break" inside.
 
If you have or can borrow an ohmmeter you can determine exactly what happened to the bad cables. Check for continuity between the pins on either end of the cable, and then test for shorts between pins on one connector. Wikipedia will tell you the function of each pin.

Most of the bad cables I've inspected had wires that broke where they connect to the pin. They are fairly easy to fix unless the connector shell is molded onto the cable.

Lol, yeah, I have one, but I am far to lazy to do that, would rather spend another few bucks on another cable than try and fix it. I think this time I will just buy a few of them for back ups, the cheap 5-6 buck ones since they all seem to last the same amount of time. I just wanted to make sure it wasn't something I could stop from happening, but if its just wires breaking inside I guess I will have to live with it.
