ok, so i finally decided to upgrade from 939 to am2. i got a msi board, amd 5200x2, thermaltake ps, and mushkin ddr2800 (2x1gb). i hooked it all up, and basically only 256 mb of ram are read at post, and windows won't start. it gives me the list to run on safe mode, etc., and no option works. just keeps looping. so i figured the msi board was shot, since it was an open-box buy, and got a dfi infinity nf570-m2/g, which i wanted in the first place. set it up to find the same thing, so i know it's not the board. i assumed it was the memory then, and replaced the mushkin with a 2x1gb set of ocz (still ddr2 800). same deal. it can't be the memory. i know it's not the power supply or my old hard drive, cause i'm using my old setup right now, with the new thermaltake ps. the only thing left seems to be the cpu, but it doesn't make sense. Any ideas? can it be a bad cpu? oh yeah, and i cleaned all the compound off the heatsink, and re-applied some arctic silver in case there was too much compound. that's not it either. it just doesn't seem right that a bad cpu would even post at all. plus the bios reads the correct cpu info. help? anyone?
