-Don't know if this is the right sub-forum but its the only one slightly about electronics, feel free to move me - Ok occasionally (and I mean occasionally - if it were happening all the time it would be much easier to solve by elimination) I am getting shocked by all parts of my rig, it could be either of the two CRT's, any of the cables or the main tower itself. When this is happening I have sometimes quickly got my multimeter out and using the bare wall as the ground (its an old barn) I can detect a fluctuating voltage between 0 and about 1.5 volts (its a digital multimeter) the numbers jump around all over the place tho which is making me think that perhaps it is a static build up? - I'm not very hot on the workings of electricity but I muddle by. It has to be said that I did think it was my old PSU (an old chieftec 320w from the first year of uni) but that recently blew and I treated myself to a shiney new system with an OCZ 600W PSU so no longer think that it is hardware at fault. I have checked all cableing for exposed copper and double checked my PC that it isnt earthing a live through the case but all is well. This has all started happening since I moved to this barn (I don't trust the ring mains here - and am slowly replacing all the ring main circuits and lighting circuits but don't plan to do the area where my PC is situated for a long time) Could I drive a metal pole into the ground outside and attach a cable to that and through to the case of my PC to ground this charge? Do any of you think it maybe isnt static charge? I'm a bit lost to tell the truth and it is driving me round the bend trying to find the culprit when it seems a few minutes after I get a shock it no longer gives one out. TIA ferg
First check if the AC power is just as high as in the house. Because most garages and barns in Europe got a higher voltage (280V or something). And you could try to ground the pc with a cable. It happened from the moment that you moved to the barn, so I don't think so. I think that the barn isn't grounded enough or the AC power is too high.
Thanks mate - interesting stuff. Can I use a bog-standard multimeter to test the voltage in here or do you need something special?
Yeah a standard multimeter will do. This is also possible. If the multimeter shows a normal volt rating, you might need to let an electrician check the wires.
