I have a Sony Vaio VPCF11SE, i7 QM 720 CPU running Win7 home premium.
Yesterday, after an hour or two of mostly just surfing the web, my laptop just suddenly died. There was no BSOD, noise or any other forewarning, it just went black. Due to battery problems, similar things have happened before when not plugged into the mains. The difference this time was that when starting again, Windows did not seem aware of the crash. Otherwise, I normally get the screen suggesting to boot in safe mode since it was shut down unexpectedly, but now Windows just booted as normal.
Once in again, I had a look at the Event logs, but the only thing of interest was an entry saying something about "unexpected shutdown" or similar. The same type of sudden shutdown happened once or twice more, after only a few minutes.
Then matters became worse, as the machine started refusing to boot at all. It powers up and I hear the blueray drive waking up, but nothing appears on screen and it appears the BIOS never even loads.
About a week ago I migrated the whole HD to a brand new Samsung SSD, and yesterday, a few hours before this started happening, I replaced the 2 gig RAM module with a 4 gig, giving me a total of 8 gigs of RAM (2x4). But as I said, the machine had been running for a few hours with the new RAM before this problem emerged.
I tried removing the new RAM, swapping the two modules, and removing and re-fitting the hard drive. I have not yet tried using the old hard drive instead.
Can anyone make a qualified guess as to what might have happened? I assume some hardware has become damaged somehow, but I don't know how to proceed from here...
Thanks in advance.
1Is the laptop heating up? – terdon – 2013-01-10T14:39:55.087
Yeah, this one is not great handling heat it seems, so the fan is very loud and the machine gets pretty hot even under moderate loads. But then, it's been like that since I bought it 2-3 years ago and there has never been any problems. – Peter Herdenborg – 2013-01-10T14:42:11.070
Good that you have the other drive as a backup of your data! Since it happened after the memory upgrade I think that's more likely. So you have put back the old memory sticks now and still no booting? – Nicholas Tolley Cottrell – 2013-01-10T14:48:15.730
Yeah, that's a relief at least, it it turns out the SSD has fried too. I did try removing the new RAM module, using only the original 4 gig module, but I never tried putting the 2 gig module back thinking that would probably not help. – Peter Herdenborg – 2013-01-10T15:14:05.367
