one of the many times ive completly dismanteled my laptop to get the mother board out. i didnt break anything and it all went back together correctly. but for some reason my laptop shuts off on me randomly. the screen will go black and then the fan will kick in loudly and then there will be a funny noise from the speakers and it shuts off then. it did this when i replaced my 2something whatever memory stick with a one gig. i ended up having to take the 1 gig out and put the old stick back in. the 1 gig works fine. its in my sisters laptop for the mean time. it didnt do it after i switched the memory back. and now my wireless isnt working. the wireless modem isnt loose. i took it out after it wouldnt work and reinstalled it and checked both connections. it did this before when i took it apart to fix it. and i took it back to my uncles computer shop(where it was bought) and he said it was loose and then proceaded to tell me i dropped and all this other crazy crap.(the bottom line is hes a dick) and now i cant get the wireless to work. im actualy on the laptop right now. ive got it connected with an ethernet cable. and it hasnt shutoff surprisingly. any help would be greatly apreciated. if you can help me feel free to text me as i wont be on much do to this POS messing up. 262 902 8708. my names leif
