Specs: Gigabyte GA-M55sli-s4 mobo (old proc amd ath 3500+) ocz 2x512 ram mobo website: http://www.gigabyte.com.tw/Support/Motherboard/CPUSupport_Model.aspx?ProductID=2310 new proc: phenom x4 9850 black edition i get no output to the screen after installing hte new proc. installed it once, no output. took it off to update bios and installe it again (didn't replace thermal paste b/c it was on for literally 10 seconds first time). reset CMOS also, still no video output. took off and put on old proc - POST works. thoughts? was it b/c i didn't replace thermal paste or what? i know cmos was reset and BIOS updated to F11J Beta before i took off the new proc b/c when i put the old one on all my settings were default and it displayed the new BIOS version. need any more details? edit: looked at the AMD proc, seems some thermal paste leaked down to the pins. NOT ARCTIC SILVER 5. it was teh pad that came with it, meaning it should be non-conductive and not make a difference? It's definitely not enough to be blocking contact between the pins and the mobo also, shouldn't matter that its the black edition, correct?
