First off here's my system specs:
Windows XP Pro Edition
Matsonic MS8157E Mobo
AMD Athlon 1.1ghz (NOT overclocked)
BFG Tech GeForceFX 5200 256mb
Soundblaster Live 5.1
Samsung 52x CD-Rom
Seagate 160gb 7200rpm HDD
1024mb Kingston PC2700 DDR SDRAM
For what it's worth, my DX diagnostic:

Now onto the problem. My computer runs fine, except when I run most of my games. Randomly during games, the system will hard lock and I have to manually restart it. It also did this with my old video card, a PNY Geforce4 Ti 4600, although with that card the crashing was very random happening between 5 seconds and 5 hours, the new card is almost instant.
Some things I've done to try and solve the issue:
Flashed the BIOS and updated it (successfully)
Moved RAM around, tried each individually in each slot
Updated video drivers half a dozen times.
Reinstalled DirectX half a dozen times.
Installed and reinstalled motherboard AGP software, along with all the other motherboard software.
Taken the side off the case, and bought enough fans to put everywhere possible in the system (even tried a box fan against the side).
Replaced the heat sink on the processor, including new heat transfer goo.
Upgraded from a 300w power supply, to 450w.
While looking through Windows' error manager, I found this:
Source: Service Control Manager
Event ID: 7023
The Computer Browser service terminated with the following error:
This operation returned because the timeout period expired.

At this point I've lost all sense of what it could be, besides a faulty agp slot (games run just fine with the onboard video), or a problem with the processor, as they're pretty much the only 2 things I haven't replaced in the system in the last year or so. The video card is brand new, power supply is less than 2 months old, motherboard is about a year old now, processor is going on 4 years old,
hard drive is less than 4 months old. If anyone has any suggestions I'd greatly appreciate it.
