Since yesterday I have the same problem. While playing UT2004 my computer just restarts itself.
My system specs:
----------------
* Processor: AMD Athlon XP 2400+
* Motherboard: EPOX EP8K9A2+
* RAM: 1 GB Infineon DDR PC-333
* Graphics card: ATI Radeon 9800 Pro (256 MB)
* Sound card: onboard
* Operating system: Windows 2000 (Service Pack 4)
* Latest UT2K4 patch (version 3339)
* Latest Catalyst driver (version 4.11)
This hardware configuration hasn't changed since the german release of UT2004 in march.
Things I have already tried:
--------------------
* Virus scan with AV Personal (nothing found)
* Spyware scan with Ad-Aware, Spybot S&D, a2 (nothing found)
* Check for hard disk problems with chckdisk (everything OK)
* Check for RAM problems with memtest86 (passed 3 times without a single error)
And it is definitely
not overheating. I have a fan at the bottom of the front panel for fresh air and one at the top of the rear panel to blow out exhausted air. In addition I am monitoring the CPU temperature as well as the case temperature, so I would have noticed any difficulties.
In fact I never experienced any problems so far. It all started with installing the latest patch (v3339). First the problem with Kerio Personal Firewall discussed in
this atari thread. There was no problem with any of the patches prior to version 3339. And now those ingame restarts.
I will try downgrading to version 3323 again and see if that solves the problem. I'll let you know...
