Hi Everyone
Although I am a fairly experienced user and and have managed to solve every problem that I have encountered, this one has me foxed!
So hope some of you more 'Tech Savy' Guys, may be able to help me.
OS Windows XP Pro
Motherboard Gigabyte GA P35 DS 3L
Graphics Card Nvidea 8800 GTX
Monitor 40in Sony Bravia Flat Panel TV
Everything was working fine, until one day when I booted up and saw this strange occurance as blocks of uniform lines were all over the intro Screen.
When the Desk Top came into view all the Colours were Garish and the Icons were so big, that you couldn't get them all on the Screen
So with great difficulty I managed to get to the Control Panel and looked at the Settings, which were showing as 640 X 480 with Colour at 4 Bits and although I could move the Slider to Show the Correct Resolution, Nothing actually happened, the resolution stayed exactly the same, even when I did 'Apply' 'OK' which were also hard to get to because everthing showed up so large.
Every time I boot up Windows asks if I would like to change the resolution for better viewing but nothing actually changes, everything stays the same.
When I go into the BIOS it is different, I get a perfect Screen at the right size with all the various options.
I even removed the CMOS Battery and reinserted it to clear the Bios before I reset it.
I've even done a Clean Install but it doesn't make any difference, as the Resolution doesn't alter from 640 X 480 with Colour at 4 bits.
If I were able to alter the Screen Resolution and the Colour, then I 'Think' the lines might disappear and everything would be back to normal but it will not hold or adjust to any other Resolution apart from 640 X 480 X 4 Bits Colour, as moving the Slider in Settings doesn't actually make any Physical difference.
Its also very difficult to click things like apply and OK as everything is so big they are off the Screen.
I've also tried different Hard Drives but it still doesn't make any difference.
I'm not very technically minded so please try and explain what I should do in very non technical language.
Many Thanks and hoping you can help.
