Hello, Please help! I'm using a second computer for this post because I upgraded to ESET NOD32 Smart Security 5 last night, shut down my PC and today when I tried to turn it on, it will not boot at all. There is power to the PC, so that is not the problem. I've done a diagnostic test where you hold the Function key down while powering on and according to Dell, there is a problem now with the CPU or Motherboard. NONE of these problems existed prior to last night. I am using MS Vista Ultimate on a Dell M1530 laptop. I've read other posts where people had problems booting into Windows after installing version 5. What will ESET do to help me?
