My home PC's monitor Samtron 56V [samtron.com] Ficklers at 800x600 (85hz Adapter Refresh Rate) - what could have been wrong?

do you have speaker cables near by?

Failing that sling it out the window from the fifth floor. It wont fix the problem, but it is fun (only done a third floor myself :))

Rock and roll man. What fun I had clearing it up with a hangover the next day. We were the coolest students in the whole damn ghetto. We did not have a TV to watch though :)

Are you sure it's running at 85 Hz?

Sometimes monitors give the impression they are when they aren't. Use a diagnostic. Not sure which one but try benchmarkhq.ru

Also, change to 640x480 with 256 colours. Still getting flickers? If it only part of the screen the monitor is faulty. If it's across the whole screen then try another video card.

It's also worth trying it in another location. Remove all mobile phones, speakers, etc. In fact sometimes even washing machines (!) cause inteference.

Well not inteference...definately not that! The screens Left hand Side corner TOP and Right hand Side corner BOTTOM - Ficklers!

And yes it is 800x600 (85hz Adapter Refresh Rate) 256 colours.

Here is my options:
1) Does it mean I have to re-install drivers?
2) Is the video card not properly fixed OR maybe damaged?
3) There is something wrong with the monitor itself.

Please Help!

First thing is always to go to the manufacturer's website, download the latest driver and install it. If that doesn't work, try searching the web to see if anyone else had a similar problem. Maybe they found a solution...

Quick option try it

>>Is the video card not properly fixed OR maybe damaged?

Do you have another monitor you can try in its place, if that works you probably have a hardware problem.

Try putting it in different places around the room.

I recently set up offices for 400+ engineers and designers in an adjacent building. About 1 in 10 monitors had a flicker problem in the upper corners. In some cases a move of a few inches solve the problem... in others we had to swap the person to another part of the floor.

The problem was found to be caused by electrical power cables (240v) in the ceiling that fed the fluorescent lighting. It didn't matter what we did we could not solve the problem. It was something unique to the building and those particular monitors (Dell)

FYI.... the problem never occurred with flat screen monitors.

I'll second the power cable issue - same thing happened to me - main power came into the house right next to my desk - flicker city.

Also, have you just tried a lower refresh? some monitors just can't take the higher refresh. I had one monitor that would flicker like mad at 85 but ran great at 74. I see the specs say it should do 85 at 800x600 but worth a shot at something lower.

Now this is really getting interesting, yesterday I could not solve the problem – I re-installed the drivers, open the CPU and check whether all my cards were intact – I was thinking of opening my monitor but was too fed up with the whole thing.

I tried keeping the monitor in different angles (in the same room), I didn’t connect my keyboard – mouse – speakers etc. Tried connecting directly to the power supply, without any spike guard – But no luck :(

Also, have you just tried a lower refresh? But doesn’t help either…

Maybe I will try shifting it in different places of the house…and the second option would be trying it in different building all together. If nothing works out then maybe a boat anchor would be good idea - Thanks guys for all your inputs :)

>What should I do?

1. Get a new monitor.

2. Move home, so you are no longer under those electricity pylons.

3. Learn to blink at 85 Mhz ;)

I had this problem because I only had 1.5 GB on an 80 GB HD.

The MS wizard suggested that there wasn't enough free space on the hard drive (which apparently the video card uses when it doesn't have enough memory) - I deleted @11 GB of stuff, defragged and it stopped flickering.
