I'd pester the machine's maker why it doesn't work proper, but a big clue is that 992 memory.
You may have onboard video memory and that, plus onboard sound cards usually results in some games just never work proper.
Things to review:
1. Microsoft will not install MOTHERBOARD DRIVERS.
2. Microsoft will not fetch latest MOTHERBOARD and other drivers for you.
3. Microsoft will not update your BIOS!
4. Given 1, 2 and 3, what have you done to assure such are uptodate?
5. The 992 MB RAM is a gimme that I would try it with just a 512MB stick of RAM.
Best of luck, but it looks like it's just a bum machine that needs to have it's maker fix it.
First off here's my system specs:
Operating System: Windows XP Professional Service Pack 1 (2600.xpsp2.030422-1633)
System Manufacturer: MATSONIC
System Model: MS8157E
BIOS: Default System BIOS
Processor: AMD Athlon(tm) Processor, MMX, 3DNow, ~1.1GHz
Memory: 992MB RAM
Page File: 978MB used, 1460MB available
DirectX Version: DirectX 9.0b (4.09.0000.0902)
Card name: GeForce4 Ti 4600
Manufacturer: PNY Technologies
Display Memory: 128.0 MB
Current Mode: 1024 x 768 (32 bit) (60Hz)
The problem is, whenever I try to load a full screen game, the screen goes black, the sound starts skipping, and I have to hard reset the system to get out of it. I've checked my drivers numerous times, I've got the newest video card drivers, have DX9, and I've looked through the hardware manager and there's no conflicting IRQ's. The card will display my desktop, movies, etc just fine, but when I try to play certain games it locks up. It's not even all games, I can play UT just fine, and Tribes1, but if I try running Tribes2, Everquest, Morrowind, and a few others, it crashes.
I thought it may have been overheating, so I cleaned off the fan / heatsink on the card and it still does it. I've got a CPU fan, video card fan, plus 3 more case fans and nothing's overclocked oncesoever. Any help would be appreciated
