Hi, I couldn't find an appropriate section but I'm guessing this is as good as any. Basically I have just built a new PC, this is what I have in it - Antec Twelve Hundred Ultimate Gaming Case Intel Core 2 Quad Q6600 2.4GHz 95W G0 Stepping Asus Striker II Extreme nVIDIA nForce 790i Ultra SLi Socket 775 Corsair HX1000W Modular PSU Asus Silent Knight II CPU Cooler OCZ 4GB DDR3 PC3-10666C6 1333MHz ReaperX (2x2GB) Dual Channel DDR3 Compro VideoMate DVB-E700 Digital TV Internal PCI-E Asus GeForce GTX 280 1GB PCI-E 2.0 Microsoft Windows Vista Ultimate SP1 64-Bit 3 x Samsung SpinPoint F1 750GB SATA-II 32MB Cache LG GGC-H20L Blu-Ray Reader & HD-DVD ROM Serial ATA Drive Dell Ultrasharp 2408WFP 24" My problem is that I don't seem to have any stability in Vista, it crashes or rather freezes as I have never seen a bsod but everything will lock up. I have no consistency as to when either as it could be while logging on or opening the control panel or updating the system. I have installed all the latest drivers and flashed my bios and I am now lost. Can anyone help please?
