Dual head messed up!

[jlianes]

I have a problem when running in dual head mode. After a short!!! peroid of time if I lets say maximizes a window or scrolls down, the screen just gets messed up, and the computer still works fine but the display is unreadable. It sometimes also happens in single head mode.
Is it driver related, or is my video memory just screwed?
Sincerely
Joe Lianes

Might be your IRQs are screwed, or anything in your computer is not working right either. Mind giving us some more info, like IRQs, system specs, DirectX version, which OS you use?

I'm running Win ME on my K7 Pro with an Athlon 650. The video board is alone on IRQ 11. Direct x that ships with WIN Me. I had same problems with win 98se. I'm running the Beta 6.01 drivers.

Could we have a full list or irq's we like looking at them you know.

maybe force AGP 1x mode? I know for my card i have to or else i'll get a garbled screen unpredictably... lines going thru screen and such.... and it's not the mobo, tried several mobos now

Jesta784 you are right that's exactly what I get. The weird thing is that it never happens during games, but mostly when running Outlook Express or I Explorer.
I haven't tried the agp 1x setting. but I will.
My IRQ table is as follows:
00 system timer
01 Keyboard
02 Programmable interupt controller
03 SCI IRQ used by ACPI bus (doesn't work)
04 Com 1
05 Creative SB 16 emu
06 Floppy disk controller
07 LPT 1
08 System CMOS
09 IRQ holder for PCI steering
09 Accton EN1207 Ethernet
10 Crative SB live
10 IRQ holder....
10 AMD 756 USB Controller
11 IRQ holder..
11 Matrox G400
12 Mouse
13 Numeric data prosessor
14 Primary IDE controller
15 Pci bus master dual controller
15 Secondary ide controller

Well change to AGP 1x seems to help me out!
