Hello everybody, this is my first time on Bleeping Computer, so I hope you're as good as it seems
I bought a few months ago a Samsung Laptop (NP530u4e-s02fr), and last month I removed Win8 because I was bored of it (like ... really bored), and reinstalled Seven. Everything was fine then, apart from a little lack of memory two weeks ago that I solved by adding 4GB (I had an empty slot), for a total of 8 GB.
But yesterday evening, while I was peacefully surfing on the Internet (gmail, facebook ..), my computer began to be really slow. It became impossible to load a webpage. At first, I naturally rebooted the PC. But no change, it was still really slow : it took about 10 minutes to launch the TaskManager ; and once I could access to it, I was surprised that everything seemed normal : (RAM: 1,5GB ; CPU : less than 30%). Temperature is normal too. So I reboot the computer, in SafeMode this time, and this everything is working fine. No slowness. So I use that chance to check if I have no virus infection, and according to MBAM everything is perfectly fine. That's at least a thing.
After a quick look on my old friend Google, I find similar cases, and in most of them it seem to be a dying HDD problem. So I install HDTune, schedule a complete CHKDSK scan, reboot in normal mode. At the beginning, no slowness so I launch a HDTune scan, and here are the results :
This is normal mode :
As a comparison, this is SafeMode :
As I don't know what to do with those results, I say to myself "well, looks fine ..", and guess what, 10 seconds after it becomes really slow again. So I try to launch a second HDTune scan, but ... no way. The HDD Speed was oscillating between 0.01 MB and 0.3 MB per sec (yeah ...), but above all it took about 2 minutes to reach the ten first seconds of the scan (Don't know if you see what I mean ..).
So now I rebooted in SafeMode, everything is fine here, and I hope you can help me ...
Being abroad till end of December, it's gonna be hard to get in touch with Samsung's CustomerService ...
