I built a new PC in November 2011 and it was fine for me up until late December when I started getting frequent, irregular BSODs. I haven't been able to narrow down what's causing them, sometimes they are under high load, sometimes when the system is idle.
Specs are as follows:
Intel Core i5 2500K 3.30GHz
OCZ Agility 3 60GB 2.5" SATA-3 Solid State Hard Drive
Seagate Barracuda Green 2TB SATA 6Gb/s Hard Drive
Kingston HyperX Genesis Grey 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz
Asus P8Z68-V Intel Z68 (Socket 1155) DDR3 Motherboard
ATI Radeon HD 5850 Extreme 1024MB GDDR5
Windows 7 x64 Ultimate - Full Retail
Aged of OS Installation is since build - Nov 2011
