Windows 7 - Computer freeze while playing MMORPGS

Hi everyone,

I have a problem running MMORPG games on Windows 7, they are: warhammer online and Aion. At some point during game (could be anything between 5 minutes and hour) the game freezes and speakers start repeating annoying sound (almost always same sound).

Can you please help to understand the nature of my problem and fix it?

I have tried following:
- Run Aion as administrator
- Run Aion in WinXP SP3 compatibility mode
- Disable system notifications for all accounts
- Disable firewall
- Install native windows GPU drivers (prior I had ndvidia latest drivers)
- Use pci network card (I've read about problems with Atheros netwrok cards) and disable built-in one
- Run FurMark test for maximum PC load
- Run BurnIn test to load: CPU, GPU, RAM, Network card, Hard drive
- Disable memory remapping in bios

What I have learned:
- I usually set up burn in test to run for 6 hours. All tests before I replaced newtwork card whcih did not stress it were successful. Two of two tests which stressed newtwork card result in same freeze. After network card replacement two tests whcih also stressed network card were successful.

My system configuration is following:
Windows 7 - 7600.16397
NOD 32 v3
3 GB of virtual memory

My hardware is:
Hard drive - 3.5" SATA II 500 GB 7200 rpm 32 MB WD Caviar Black (WD5001AALS)
CPU - Intel Core 2 Quad Q8200 2.33 GHz Socket 775 Box (BX80580Q8200)
Motherboard - Socket 775 Asus P5QC (90-MIB4C0-G0EAY00Z)
GPU - PCI-E nVidia GTX260 896 Mb Palit Sonic 216 SP Retail
Power unit - ATX Chieftec 500W CHP-500A
RAM - Kingston DDR3 2GB 1333

Thx in advance,

are you running through a router? And if so have you forwarded the correct ports for Aion?

2106 - Both TCP/UDP
7777- Both TCP/UDP
10214- Both TCP/UDP

those are the ports you want to forward if you are running a router. Otherwise, I'm curious to hear what others think. I also am having an Aion related issue. Not quite the same, more of an annoying factor, yours is keeping you from gaming, which really sucks.
