Help....Screen Flickers on and off

  1. Is it possible for a video card to be to slow? I put a GF4 MX440 64mb pci in my new system and now my screen flickers ( kinda like when you change refresh rates ) when scrolling and opening new windows. I have tried everything I can think of to fix this and the only thing that will work is turning the hardware acceleration off...The card works fine in old system, same OS, updates, patches, software....Here are specs for both.

    Athlon XP 3000+ 400mhz 512 cache
    512 PC3200 DDR
    MB Gigabyte 7VT600P-RZ
    GF4 MX440 64mb pci
    Maxtor 20 gb 7200rpm ata133
    Maxtor 30 gb 7200rpm ata133
    DVD player
    DVD RW16+
    450 watt ps

    Celeron 1000mhz 100mhz 128 cache
    256 PC133
    MB AOpen Mx3s-t
    Seagate 80 gb ata100
    Seagate 160 gb ata100
    300 watt ps

    I would appreciate any help.

    I am planning to buy new card but that is in a few weeks when I have extra ($)

    What resolution are you trying to run it at? Also does turning down hard ware exceleration help?

    800x600 32bit and no turning down does not does though. Also have tried all resolutions. OS is 98SE.

    i've seen this problem before, and it was caused by lackluster graphics cards, but i doubt your card would balk at said resolution. it is possible that your monitor/ac line is the cause, so i would move that monitor to another location and computer and test it there.

    I took the GF mx440 out and put a 16 mb agp 2/4x in, this works fine. Both are PNY but the agp uses SIS drivers and pci use nvidia. I put the GF mx440 in old system, works fine. :confused:
