[Gardor]

Unless ******* and viruses have turned a new leaf what did I do that fixed my pc. It was glitching every so often the programs would say not responding and have a white film over them I couldn't do nothing I did the following. Scanned for viruses with Nod 32 scanned with spy bot (found faults) scanned with pc utillities (found faults) I also booted and tryed fixing with the windows cd the final thing I tried was to boot in safe mode which was the last thing I did and it started working so was it the safe mode and the only thing I can see altering is the visual display. did this fix my pc. Just dont want to do it again thaTS ALL iphone unlock
