Finally got the AMD Blackbox FX 8350 on sale for $89.99 delivered from Monoprice.com. I am having a terrible time trying to seat the heatsink fan. I'm is my 60s and have short stubby fingers. Taking the old AMD FX 4100 out was a no brainer, of course. For the life of me I can't get both clips to latch. I have the heatsink laying on the CPU with one latch for the time being. The system seems to be running sluggish and strange. Do I need to do anything else to the system, bios etc. The MOBO is a Gigabyte GA-990 FXA-UD3 bios F2 with an id of 8A02BG10. It shows the cpu with all 8 cores running in the task manager but some programs are acting goofy. CPU-Z would not run so I deleted it and can't seem to get the new d/l to work. Starting the control panel took time to load. Everything worked fine before the switch. I have a Corsair H2o water cooler maybe I should install it since I want to crank out 5.0 Ghz out of this thing in the near future. Any help would be greatly appreciated. Thanks.
