I have a friend's Gateway laptop M-6866. The topic started here: http://www.bleepingcomputer.com/forums/t/577308/gateway-slow-to-start/ . I have used bleeping computer tools to clean it of malware and such before. Recently it has had Firefox issues and "Cannot load XPCOM" has come up twice. I've fixed that by re-installing Firefox each time. The first time none of his browsers would work! My friend had not had it back from me for much time when he brought it back because of a slow boot and there was yet another PUP on it. Side note: the owner has let the machine run until the battery completely died several times.
Anyway, the computer operates fine EXCEPT for the amount of time it takes between the welcome screen and the appearance of the desktop which is up to 90 seconds or so. Could it be something scanning at start-up? How do I investigate this? There was a period when it quit doing this but it is back to it's craziness again.
On the previous topic page we cleaned it of junk and tried to run some hard drive checking programs. Gsmart control made it BSOD.
