I need some help trouble shooting a problem I have. I upgraded the CPU in my current system from a P4 3.2 Ghz to the aforementioned Quad QX6800. The system hangs on start-up, no POST and after a few minutes (2-3 mins) the CPU cooler fan stops operating, chassis fans are still running. I list the essentials on my system below. Asus P5W DH Deluxe (Bios 2303) Intel Quad Core Extreme QX6800 PNY 4GB (4x1GB) PC2-5300 DDR2-667 ATI X1950XTX 512 MB Zalman CNPS9500 LED CPU Cooler Thermaltake 700W Toughpower When I replace the QX6800 with my original P4 CPU the system operates as normal. HELP greatly appreciated. Thanks PCBUILD maintains hundreds of useful files for download visit our download web page at: http://freepctech.com/downloads.shtml
