I have horizontal lines running through my graphics. Online as well as in Adobe photo.
Have clean installed W2K, intstalled a new mobo and new video card. Updated drivers, updated chipset. Tried new monitor. Same problem is still there. Am at wits end. Can someone please advise? Thank you.

I have no clue. heres atleast one thing is your card fully in the slot.

yes, i am afraid it is.
I have also taken out the floppy and all cdr, cdrw and zip drives. Nothing in there but Nic, video, sound card, mouse and KB.
Like i said, swapped out MB, video card and monitor. Formatted and installed 2000, used to have W98 with same problem, but i fixed it in W98 by disabling active desktop. Can't find a fix and am desperate...someone, please help!!!

what kind of video card is it?

i had a similar problem with an old 32MB pci video card.
chances are it's not a hardware problem, if turning active desktop off seemed to fix it; it might be in the BIOS.

hit the DELETE key during bootup to enter the BIOS setup.

try disabling CPU to PCI write buffer, which should be in PnP/PCI configurations.
also, try disabling "video BIOS cacheable" in the chipset configurations.

let us know if that works.

Thank you for your suggestions, A. I tried them all to no avail. I have since swapped out power supplies, memory and took the computer next door to rule out elect. interference. Tomorrow, i will swap out CPU and that will make a 100% change of every single component. Will let you know how i make out. There is absolutely NO information on the net that addresses this particular problem!

it could be your video cards ram or your monitors cable is stuffed difends on what type of line your getting
