I have an issue with my laptop with Windows 7 OS. My issue is everytime i boot up my laptop, there always system repair option before windows logo apears. I have been run the system repair but the system repair cant fix it, so that option still there when i boot up. When i try to boot windows normaly, the boot came with long time than usual and then bring me to my desktop finally. But now almost all of my program start crashing, even windows services called DCOM start to terminating. I already try the clean boot with just windows services running but still the problem exist. I thought its kind of malware or viruses with my laptop and i want to reinstall my OS. My problem is, i argue that reinstalling can fix the viruses/malware because i have read in some article that states "viruses can still in our system even we reinstalling the Windows". Is that states is true? Or my argument is wrong? Please help me understand this confusing thing.
