it is less than a year old,,,, i bought it from a guy that "supposedly" won it from an office depot,,, and i know it was originally a office depot computer because of the things that were in it labeling Office Depot, so i know that part is true,,, the model number is VGN-FE670G..... it worked fine for me for the first couple months,,, then i started having these issues. I am trying to get some proof of "winnings" from the guy i bought it from then Sony says they will cover it under warranty,,, but i am having a hard time getting the guy i bought it from to get the necessary "proof of purchase", thus the reason i am trying to do this myself. When i first got the SECOND hard drive, i installed simply using the restore disks,,,, did not format first... it did work briefly, but now i cant do ANYTHING to that hard drive,,, wont format or chckdsk,,, nothing,,, and if i try to start it without any disks it says it has no operating system...what really has me stumped is that it wont even format.
Currently i was running the scan disk option to scan for and attempt recovery of bad sectors,,, and it gets almost all the way through phase 4 then just as its about to complete it gives the BSOD with teh F4 error. this is on the ORIGINAL hard drive,,, i am sending the second hard drive that wont boot back to Fujitsu today.
