My 840 Pro is suddenly very pedestrian!

hi guys,

I got a major issue with my ssd or maybe my computer. My computer has been running great until last night when I did a spring clean inside the case, I unplugged everything, cleaned the inside of the case and plugged everything back in exactly where it was. As soon as I turned the computer on it became apparent that the boot time was very slow and in fact when I reset the computer it was stuck on the windows logo for a bout a minute. sometimes everything boots up fine, then the computer freezes intermittently in between tasks.

 

Now, I went into Samsung magician and did a benchmark and I was shocked to see that the results were very poor, I mean HDD poor!

I double checked all the settings i.e ahci, is it plugged in the sata 3 or not and everything is ok, in fact I did all that when I built the damn thing. Can it truly be because I simply unplugged everything when I was cleaning the computer that caused the issue? can static do this? because I wasn't grounded while I was cleaning the inside.

 

i walk across carpet in my socks while holding computer components. with that way parts are made now a days it will take alot of static to kill a computer part and also an ssd is enclosed.

have you changed anything with in the bios?

i work with compter all day and one thing i do see a lot of in SSDs is the Samsung 840s pro or none pro come back with issues. the sandisk ultras have a better left with customers.

you have ran  a benchmark test and poor results. i would call Samsung on this one. 

If it is still under warranty, you might want to replace it.

well I noticed that magician is now saying that im not connected to a sata3 port, when clearly I am!

okay, I plugged the sata3 cable into another sata3 port and its still telling me in magician that 'you must connect your ssd to a sata3 port'

I know I can RMA it, but it was running perfect then suddenly stopped working properly after I plugged it in after un-plugging it.

Did you try a different sata cable?

I tried another cable, same thing. Now something weird is happening. I was changing the dvi to hdmi and it took 5 minutes to pick up the signal and display the picture. With a dvi cable it instantly picks it up. 

Also I uninstalled my graphics card and now when I am re installing the graphics card and installing the drivers the pc crashes and switches off. could it be a motherboard problem?

Also within magician for a very short period it was telling me that I was connected to sata3 but benches were still crap. Other hdd software was telling me the ssd was healthy. Now it's telling me that I need to connect to a sata3 again. 

I spoke to Samsung this morning and they told me to do a factory secure erase and that should solve the problem.  but I doubt it. 

 

Well I just rang them back and told them the secure erase didn't work. They told me to send it back to them. Hopefully a new ssd should do the trick.

I'm just really worried that the motherboard is screwed. but what I was thinking was if the motherboard was damaged in any way surely it wouldn't work at all rather than being temperamental. 

Could it be the power supply? As I'm reading on forums the things a faulty psu can do

Update: yep it was my ssd. I had a Seagate hdd lying around and I installed windows on that and everything is fine. cant believe its only 8months since i installed it. Really Pissed with Samsung right now. it's going for RMA tomorrow. I'm going to sell it and buy a Kingston. Do you guys recommend any other ssd with same speeds as the 840 but more reliable?

TBH working with WD HDDs over the years has made me realise what beasts they're. 

This scares me since I have a 120gb 840 Pro. Hope mine fairs better. Sorry about yours. :(
