Hi all,

So I have an 120 gb 840 EVO in my machine, and it was amazing for the first 7-9 months that I had it. Everything booted up very quickly, and it was seconds to the windows screen. One day, my machine required a restart and for some reason, ever since then, it takes between 2 and 3 minutes to show me the windows screen.
(i.e. the one where you have to press any key to continue to the password screen). However, from what I can tell from other people reporting problems with their 840 EVOs, everything slowed down for them. I have a hard drive for stuff like large games and pictures, and my SSD has windows and other programs on it. Nothing except for windows is even slightly slower. I am really puzzled as to what is up.

Also, I have run both of the software patches that samsung released and they both did nothing.

The CMOS code (if that's what it's called) in the bottom right hand corner of the screen before it shows the windows login screen is 90 for a while, and then it goes to A2 for a shorter amount of time before it shows the windows screen.

I unfortunately have a 32 bit OS, but 8 gb of ram. 1.8gb of the usable 4 is in system reserve if that helps at all. I was thinking that maybe I could upgrade to windows 10 when it comes out and upgrade to 64 bit then.

My entire system is here:



AMD A8-6600K

MSI A78M-E35

G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-2133 Memory

Samsung 840 EVO 120GB 2.5"
Western Digital Caviar Blue 1TB 3.5"

BitFenix Survivor ATX Mid Tower Case
Corsair Builder 430W 80+ Bronze Certified ATX Power Supply
Asus DRW-24B1ST/BLK/B/AS DVD/CD Writer
Microsoft Windows 8 OEM (32-bit)

and an old memory​ card read​er

Try running the free version of HDTune -- for an EVO in healthy shape it should be consistently above 100MB/sec transfer rates and access times (the yellow dots) should consistently be along the bottom edge of the results (no dots above the bottom line). There are a bunch of very clear "bad" and "good" results on this page of the 840 thread here: viewtopic.php?f=5&t=96590&start=180

You don't have to trust that the Samsung tool did what it claimed -- I found perfectly acceptable results using the free version of DiskFresh. (Which is your only option on a non-EVO 840 because Samsung denies it has any problem and doesn't allow their tool to work on it.)

Again, maybe this isn't your problem, but trying these two tools will give you some clearer diagnostics and a potential fix in the event that the Samsung one's not working properly.

Have you upgraded your SSD's firmware to the latest revision via Samsung Magician?

If no, that's your first thing to do, then leave the computer running overnight.

Then click Performance Optimization > Advanced and run that.

I have actually done both of these things before...

You'd be better off buying Windows 8 now and getting a new SSD e.g. a Crucial BX100 (240 GB for £64 on Amazon) to get yourself non-pathetic (non-Samsung) storage and the use of all 8GB, which I'm sure would feel like a whole new, better, system. Then you could think about whether to upgrade to Windows 10. The 840 EVO is a POS PITA, and having effectively 4 GB RAM must be painful too.

Yeah... Chrome has actually crashed a couple of times and the worst part about it is that 1.8gb of the 4 usable is in system reserve. I effectively have 2.2 gb total of ram. BTW if I do a fresh install of windows 8.1 64 bit, will my windows 8 (not 8.1) 32 bit key still work?

Yes, if you do a fresh install of 8.1 64bit you can use your 8.0 32bit product key.

So I decided to wait until windows 10 to install my os, and when it first booted up I was like HELL YEAH!!!!! But I had this grand plan. You see, I have a 1tb caviar blue hard drive in my system, and had some stuff I didn't want to delete on there, so I unplugged it from my mobo before updating. Upon plugging it back in, the problem returned..... Does this help at all?

Wait... so the system slowdowns only happen when the HDD is connected?

And if that's the case, the 1TB Blue may be shot with unreadable sectors, which Windows is repeatedly trying to access. In that situation, check Windows' Event Viewer, System section.

It appears so...

What am I looking for here?

p.s. how do I attach images here?

That's a service log, ordered from more recent to oldest. You're looking for any items that read "Error", pertaining to "disk". If you see any of them, click and paste the information here.

I didn't get any errors pertaining to the source disk. However, I got a number of errors at startup.

Windows failed to resume from hibernate with error status 0xC0000221.
The previous system shutdown at 10:46:24 PM on ‎8/‎2/‎2015 was unexpected.

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

The above includes criticals in addition to errors.
Also, sometimes when I want to shut this thing down, it either takes a really long time to shut down or it just doesn't shut down. Don't know if that helps or not.

At that point, I'd download Western Digital's diagnostic tools and run them on that 1TB Blue.
