Ok, I've taken my old pc back into my room, well when I turn it on, I usually get all the way to the login screen and the monitor starts getting these black lines rolling done and it gradually gets worse and then turns off.

When it turns off it makes a clicking noise. Anyway when I turn the monitor back on it usually stays on for a second then gets really bad again and turns off then I keep trying to turn it back on it will turn off basically straight away.

When I leave it for 5 minutes and I turn the monitor back on it usually stays on for like 5 seconds then starts getting bad.

I checked to see if any cables were loose but they weren't. I probably should have tested the computer first before I moved it into my room. Also I did open the computer up but that was to put a network card in and I replaced my phone line pci whatever (I'm not too tech), but I guessed that I'd replace the phone line card with the network card. I don't see how that would affect the display.

I'm not sure if I need a new cable/monitor or reinstall drivers. I'm searching around for the resource disk for my old PC aswell.

Also in device manager I went into display drivers and it said they were working fine but just incase the name of it is SiS 730s. I'll check the actual driver file name aswell then search google, haven't had much luck with the SiS 730s so far.

Was the monitor working before you moved it?

Can you try another monitor?

Can you start via Safe Mode Options choosing Enable VGA Mode?

Also check settings via Start | Run | dxdiag.exe
Look under the display tab.

Any chance you moved the monitor within close proximity of a magnetic device?

I never checked the monitor before I moved it...damn

I can try another monitor, which I will be trying in about 10 minutes.

I went to the display mode and it said everything was working fine...I wasn't sure what to do anyway.

Can you list some common magnetic devices...I thought a computer was a magnetic device (confused) hehe

Thanks for the help.

just since I search magnetism I post a few replies

high current running through
one or more cables in the wall.

Also, I have seen flourescent fixtures cause the same waviness. Is
there a desktop flourescent fixture on the desk or very near by? If
so, try relocating it.

magnetic interference will give the symptoms you
describe. Anything that creates a magnetic field may influence your
monitor. Fans, motors, large speakers, elevators etc. We had a similar
problem when we moved into our offices a couple of years ago. What we
found was that an unbalanced AC current created the magnetic the fields.
Current normally flows along the live and neutral wires, which are close
together in the cable and so their magnetic field cancels out. The
neutral/earth short can cause current to go in a large loop rather than
heading back the intended way.

Is there are large building transformer (welding machine, Xray machine,
large motor machine) on the other side of the wall? All of these can
give a monitor the shakes; ditto fluorescent desk light and pencil
sharpeners. A UPS is unlikely to help since most of the time on most
UPS's they just pass the wall current through without modifying it in
any way.

The shakes can come through the air as magnetic changes or through the
power wireing. If you rotate the monitor 90 degrees does the problem
diminish (or get worse)? Then the problem is through the air. When you
moved the monitor 10 meters did you use a different wall socket? Try
using other sockets in the room; you might find one that is a lot better
(on the other side of the neutral.)

I believe if the problem is through the air, an LCD monitor would be
immune. If it is through the power wiring, another (better) CRT might
fix the problem. I don't know whether an LCD monitor would
automatically cure things.

Assuming that the problem is magnetic, then no a LCD monitor would not be
affected int he same way. If you really moved it 10 METERS from the
original spot and the problem didn't correct then I would guess it is a
problem with the power in the house. Otherwise that would be one HUGE and
excessively powerful magnet in the home. I mean unless she is using a
super-electromagnet to prop up her dining table I doubt it is magnetism.
Try putting it on a UPS and see if the problem clears itself up.

More down to earth you may just need to reinstall your graphics card drivers.

What is listed in dxdiag as to Display Device & Driver?
If it is the SiS 730s then it is probably onboard graphics.
We can search for drivers.

I think i'll move everything from where my computer is, xbox, tv, gamecube and everything else then test it...But I already have the correct driver for it...

Also what did you actually want me to do on dxdiag? Search fro drivers...Do I need internet access for that, I can get it, just have to install the network card software so it will connect but that could take a while having to turn the monitor off and on...

I might try and set-up the internet connection now.

I just mentioned dxdiag to check the driver ID.

If you have the correct driver then that is that.

Do you actually have it on the hard drive? So that you could uninstall/ reinstall it?

By that is that, do you mean I should just keep it there, yes I do have the driver on my comp...i already downloaded the driver for it and im trying to update the driver now...if that doesn't work i will set up the network card software and try and do the update driver from the internet (that's possible isn't it?).

You can also download to any computer then put it on a floppy to transfer to the other machine.

Well I tried the driver, replaced it and now my resolution can only go up to 640 * 800 or something like that and I tried to change the amount of colours aswell, now it looks like safe mode...damn

Well by friday I should have an extra $170 AUD with the $90 AUD I already have so that should get me a decent monitor, although before I try that I will have to test the other monitor which I can't do at the moment because the other computer is being used.

Also about the graphics card driver re-install would I be able to get that off the internet aswell because I've been searching for the Optima Resource CD along with all the other CDs that come with the computer.

You most likely have loaded the VGA driver that would simulate Safe Mode.

Do you have a graphics card?

If drivers exists you can probably find them online. It just takes a bit of searching.

What exactly are we looking for? Graphics Card? I was thinking you had onboard graphics? SiS? What is Optima? What else came with the computer?
