Hi everyone,

Hello Hello,
I have been browsing the site and gotten so much useful info from here, including extremely helpful boardviews and several other very useful types of information. I am very grateful to this community, as I have actually eeked out a living from buying salvage PC's & Macbooks and repairing them. So, thank you all in advance!
I have searched and found some useful information regarding my issue, but my case is a bit different than the info I'm finding. But if anyone here can give me any useful advice, it would be highly appreciated.
