I built a HTPC for a good friend of mine around 8 months ago and he's having some issues with blue screens. I know he doesn't use the machine too much but these BSODs started occurring about a month ago. These crashes seemed to be tied to his network adapter but I haven't been able to fix them. The tcpip.sys file was the first one I tried debugging and it continued after installing a newer more compatible driver. The next blue screen I encountered flagged the win32k.sys file so I checked BIOS and made a few changes to the RAM timings. His system isn't overclocked at all and he has already updated to the latest graphics and chipset drivers. Here is the full spec: Intel Q6600 G0 @2.4Ghz ASUS P5G41C-M Green 4GB Super Talent DDR3 VisionTek Radeon HD4870 X3 600w power supply OS is Windows 7 Ultimate 64-bit I'm testing out the RAM now and will post additional minis when i can... I've already tested the power supply as well and it checks out fine. Any ideas?
