I've noticed that the freezes only seem to happen when there is heavy net traffic; browsing the web for more than 10 minutes, viewing picture heavy pages, downloading, torrenting, hosting game servers and any combination of the above will kill it, usually within an hour though sometimes it has run for longer before freezing. Running a game server over a LAN with the internet disconnected also produced a freeze up and it has frozen once and only once right after windows reached the desktop. Lighter tasks like MSN Messenger, IRC and joining game servers on other computers do not produce freezes and I can happily do these for several hours. I use FireFox as my default browser but I have got exactly the same crashes using Internet Explorer 7. Anything that is not network related does not seem to cause a freeze and I can run system intensive games and programs indefinitely.
The Specs are:
Windows XP 32-bit Proffessional SP3
XFX Nforce 780i
Phoenix AwardBIOS v6.00
Intel Core2 Duo E8400 3ghz
4GB DDR2 RAM in two sticks of 2GB
XFX Nvidia Geforce GTX 280
ESET Nod32 anti-virus
ISS BlackIce firewall
and the computer is connected to a D-Link 2640B router
So far I have:
1) Scanned for viruses and malware with no results
2) Updated Windows to the latest version
3) Installed the latest graphics card and motherboard drivers (I have installed the motherboard drivers both with and without the hardware firewall)
4) Installed several different versions of FireFox
5) Updated my Java Runtime to the latest version
6) Updated my Flash plugin to the latest version as well as running with the plugin uninstalled
7) A registry fix for a similar problem caused by MSN Messenger
8) Flashed the BIOS to the latest version using an ISO from the manufacturer's site
9) Checked component temperatures in the BIOS (they are all running at normal temperatures and my computer is not overclocked)
10) Tested the RAM with Memtest 86+ (both sticks passed 5 tests with no errors)
11) The computer crashed once while I had Process Explorer active and there were no unusual processes running and no spikes in CPU or memory usuage
12) I left the computer on for over 12 hours to do nothing and it was still running fine when I returned to it
None of these measures have produced any noticeable results.
I've considered the possibility of it being some kind of software conflict but this is a new system that does not have many processes running and I have experimented with closing down non-essential processes but nothing seems to affect it.
Thank you in advance
