I have a friend's laptop that I have been trying to kick back into shape and after gutting out the malicious viruses and malware I find that the system on every other reboot has a problem loading explorer.exe. To add something to the mix, when it does start-up, the load the machine has on boot-up take forever clear out and sometimes it will crash the machine. I don't believe it has SP2 on it, would it be safe to say that after SP2 that things could just resolve themselves? Are there any other tweaks that can be looked into for improving start-up? I have gutted what I can from the msconfig settings. Anyone want to shed some light on this?
