Hi all, any help that can be offered with this will be greatly appreciated - it's been bugging me for ages ! First of all system info:-

Pentium III 733 Mhz PC133 bus
384 Mbs PC133 Ram
Tyan TI6VG4X M/B
4x4x24 Ricoh CDRW DVD Drive
30 Mbs Fujitsu UDMA EIDE
20 Mbs Maxtor UDMA EIDE
Gainward Cardexpert Geforce2 Ultra/500
AOC Spectrum 7Glr 17" Monitor
Windows 98 OSR 2

Right then - the problems:-

1. When you try and play a DVD using EITHER Win DVD OR Mediamatics DVD Express when the film starts rolling you get strange flecks of white and green flicking about on the screen and it usually freezes and crashes - forcing a re-start.

2. When Playing UT or run Mame32 you get strange flecks of white flickering abut the screen - severity is dependant on the screen mode it's running in. Sometimes Sound Gets really crackly and stops in UT, it never did this before !

3. In UT 800 x 600 32-bit colour with the latest UT patch, running in OpenGL mode I only get an average of 45 - 55 Frames per second - which seems rubbish - Direct 3D is even WORSE !

I've messed about with all manner of BIOS settings - I've tried the Fail-Safe settings and loads of custom settings. I've tried the CD's drivers and the updated 650 Drivers - but the same thing happens. In Windows the screen looks normal. It can't be an overheating problem - I'm using the default Clock Speed settings and have more Cooling equipment in my pc than any other type of hardware !!!

If anyone can solve these problems they deserve a knighthood - I've been buggering about with this for weeks !!! :-(

thanks,

Martyn S
