So my GPU was maxing out at 99%. I did some googling, and came across conhost.exe trojan as possible culprit. When I kill that process, my GPU drops to 0%. So I think I have the problem identified. But nothing seems to fix it. I'm attaching all the logfiles from software recommended elsewhere on these forums. Also note that when I ran combofix the conhost.exe process was running, but combofix killed it when I started it up. Is that normal? Any help is appreciated...trying to avoid a reformat. checkup.txt ComboFix.txt mbar-log-2013-07-28 (11-20-07).txt system-log.txt TDSSKiller.2.8.18.0_28.07.2013_11.19.36_log.txt
