Hello, welcome to SpywareHammer.
I go by Hoov, and I will be helping you with your problem. I must ask you to do a few things for me.
First, tell me everything that you have done, if anything, to try and fix this problem.
Second, please only use 1 forum to help clear up your problem. Posting on more than 1 and following instructions from more than 1 forum will cause those helping you to pull out thier hair.
Third, follow my instructions - If you can't for some reason, or if you don't understand something, please tell me. If you deviate from my instructions, tell me, it may make a difference on where we go.
Fourth, Have faith. I will do all I can to get your computer working, and if I can't - someone else here will know something else to try.
Fifth, if we start this fix, I need you to stick with me until the end. Just because your computer is running better does not mean it is fixed.
Before we start trying to fix your computer, you need to make sure your data is backed up. Also let me know of any software you have running that encrypts your harddrive.
Now onto trying to fix your computer.
Can you reboot to safe mode?
