I have a Toshiba Satellite A135-S4467 that I upgraded to 2x2 gig of ram (paired set). Have run the laptop several days and now suddenly won't boot up. I've reseated the ram and removed battery, and it booted right up and worked fine. Shut it down, left it for an hour and it won't boot up again. Any suggestions are really appreciated. BTW, Toshiba model allows 4 gig on the dual core, but it will only read 3.1 ..checked all this out before I upgraded. Thanks :)
