Ok this is very strange and has never happened to me before I'll start from the begining.


2 days ago my 3 year old video card fried on me. Yesterday I got a new X1600XT and put it in and everything was fine and working. This morning I plugged my speakers back in and touched the case to hold it in place as I put it in. And I got shocked. With 1 finger touching it it is a tolorable slight numbing but anymore then that and it hurts. I unplugged everything and found that its the computer screen that is doing it.

Anytime I connect the ports the whole case is electrified. I don't know how this is happening. Could power be bleeding off the new card into the case? Is the card defective? Because it works just fine in the computer so far. The very last new video card I got nearly a year ago was a 6800GT and that overheated and fried within a week of having it. Which made me use my old one again which was the one that fried.

I don't think this has happened since before I put the new card in.

This has never happened before so Its stressing me out. Has anyone delt with something like this before? Thanks.

This is potentially VERY hazardous! Everything you choose to do must be with the utmost caution. I would start by completely stripping the PC back to the motherbaord and then building it up again, checking for loose wires, shorts, and anything else that doesn't look right. You really cannot afford to go lightly on this one...well, that's my 2 cents

Hey, Thanks.

I'm 95% sure its the Screen or video card somehow. This has only happened Right after I installed it last night because I've had to touch the back of the case a bunch of times before it and nothing happened then. I unplugged everything in the computer but the computer screen and the charge was still there. Then unplugged that from the wall and it stopped. So some how its coming through the cable to the video card to the rest of the case I have no idea how. It doesn't seem to be messing with the proformence of the computer at all. I tested the card on a few graphics heavy games and it worked great.

I've never taken a part a computer before. The only thing I have ever done with the insides of a computer was remove and install video cards and remove and install a hard disk drive.

Sounds like you are leaking AC to ground somewhere, and theres only a few places this can come from. The power supply, the monitor, or the recepticle/power strip they are plugged into. There is a transient capacitor tied to ground in the monitor and power supply that can go bad and cause ac leakage to ground. Also, if the polarity of the recepticle isnt correct, or you have something with a motor running on the same circuit, it can cause a backfeed. The computer and monitor, and any equipment connected to them, should really be on a seperate, WELL GROUNDED circuit. This is not always possible, but at least make sure the polarity is correct, it is grounded, and there are no motors running on that circuit. Hengis is right, this can be very dangerous, especially if someone happened to be barefooted and touched it. Do you have another monitor you can try, and a meter you can check voltages with? I dont think the video card is actually causing this, everything on the motherboard runs on low voltage dc. Even if a diode on the low voltage side leaks ac, its wont normally shock you. I would start by checking the polarity of the recepticle. Make sure nothing else on this circuit is running before you start testing. If its ok, hook the monitor back , dont touch anything barehanded, and check for voltage between the case, and the neutral side of the recepticle, and from the case to a ground somewhere esle. If you get a reading of more than a few volts, try another monitor and see if it does too. A small amount of backfeed is normal, just a few volts, and is usually caused by motors running somewhere( fridge, ac...) , but if youre getting 20, 30, 40, or more, its enuff to kill you if you are grounded good. If you dont know how to do these tests, or dont have a meter, i suggest you have someone check it that does. It would be a good idea to test the polarity of all your recepticles. You can get a tester at most hardware stores for under 20$, that plugs in, and tests for ground, polarity...ect. Youd be surprised how many people call themselves electricians, that think it doesnt matter which side the black wire goes on.

Hey thanks for all the replies.

I checked it again just now. And theres no charge to it at all. It wasn't a real shocking jolt when it happened before. You could hold your finger to it and it wouldn't hurt but it would have a numb feeling in 5 seconds. But anymore then 1 finger and it would hurt a little. And I was barefoot when it first happened. And barefoot when I checked again when nothing happened. All I did from then to now was move the computers position.

Hi gud day!!! I think I didn't make another topic because I have the same problem with Knives. my pc was running good also. Is there a posible damage on the mobo, processor or all the components on my pc? Thanks on your advise....
