Just got a new computer and wanted to put it through it's paces, but after updating half-life two, the computer just restarts itself when i try to load it. At first it seems ok, saying, "preparing Half-Life 2", then the computer gets noisey, screen goes blank and the system restarts. Sounds like it could be a memory dump? Here are the specs: Intel® Pentium® D Dual Core processor 830 3.0 GHz 1024 MB DDR2 SDRAM with 533 MHz NVIDIA® GeForce™ 6700 XL 128 MB PCI Express x16. Any ideas? Cheers.
