...and i thought i had huge problems with my lappy...
I guess it doesn't matter whether this is still in the warranty period or not since OC voids the warranty anyway
I am not an expert in all this...just telling you what i would do.
Sugg1: Get this fixed by HP service centre rather than DIY, unless you are just tinkering with it and have another lappy/desktop for the important work.
Sugg2: HP's website has a list of part-numbers (model numbers, if you will) for the replacement parts of various laptop models. Maybe you can buy/order that from HP directly.
