Help needed : Windows 7 freezes at startup with SSD (Samsung 840 Pro 256Go) as system boot drive

arcondo — Wed, 22 Jan 2014 12:08:14 GMT

I hit my head against the wall without any tangible result. Few weeks ago I bought an SSD drive in order to boost my 3 years laptop (Acer Aspire 5745G 720QM / 16Go RAM / Primary HDD : Samsung SSD 840 Pro 256Go / Windows 7 Ultimate). So I reinstalled a fresh "windows 7 Ulimate N" version and then my problems started :

- Up until now, each time I power on my laptop, it freezes and the only way is to hard shutdown it. So the "game" continues 4 or 5 times before I get into my desktop.

- I suspected a driver (display, sound, Intel (cheapset, AHCI) and I remove them to see if I'm able to fix this : No positive result.

- Then I decided to reinstall it once again and I didn't install any added software for checking whether is it fixed or not : No positive result

- I went googling and I saw that a lot of people having the same troubles so I tried to follow some solutions but still no result.

Now, I suspect that ACER and/or SAMSUNG know the problem but no fix no communication, nothing. They are just leaving people on their own.

Probably it is the last time I'm buying something from ACER.

Any insight, idea or solution to recommend ?

Thanks for your feedback.

Updated the laptop to the latest BIOS?

Updated the SSD to the latest firmware?

Removed and reseated the CMOS battery?

If you don't know if Acer or Samsung are to blame, will you be boycotting both of them?

Updated the laptop to the latest BIOS? Yes it is 1.19

Updated the SSD to the latest firmware? It is (samsung "magician" software is stating this)

Removed and reseated the CMOS battery? Not done yet but I flashed the BIOS.

If you don't know if Acer or Samsung are to blame, will you be boycotting both of them? I'll do because I think that as professionals they have to assist their customers specially when help is needed. The notion of customers is unknown at Acer or Samsung and that's why Acer for instance is loosing money right now.

Reseating the CMOS battery may not sound like it will accomplish anything, but it's a quick job and sometimes can be the problem.

Just to confirm that the problem is definitely with the Samsung drive, have you tried reverting to the original HDD to make sure the same problem doesn't happen?

Finally I know where the problem came from. It's all about capacitors.
- Means that Acer is selling laptops that could die after 3 years.
- Means also that Acer is putting in their motherboards very cheap components. Because normally in the case of capacitors the lifespan is around 15 years.
- to summarize this : I'll not any more buy from Acer whatsoever !

Ah, that's a shame. That means that putting the old HDD back in will produce the same fault. Just a coincidence that the capacitor went bad at the same time you opened up the laptop, I guess.

Folks, there's a lesson here. How far can you change your hardware before you have a different computer?

Once you change the hard drive, you have a different computer. I'm sorry, but that's whys so many people can't get Windows to work on their laptop when they change their hard drive. Laptops are more finicky than desktops, and I advise everybody to stay with their original hardware as much as possible.

This situation is not unique to Acer, as I have seen it on other forums.

I have run different hard drives in the units I have with no problems, but things do happen.

One thing I make sure of when I do this, is to go into BIOS and change from AHCI to IDE. This

way it always boots. I only run W7 Pro or Ultimate. Once I get everything working, I go here

and load the files for AHCI, reboot and wait until everything is loaded then make sure AHCI

is enabled in BIOS. If you have already loaded the OS, the link below has info on that, as well

as NForce boards, and a tip about SSD's.

True this doesn't always work, so it goes back to IDE, but 9 times out of 10 it does. One

has to make sure one does the registry adjustments.
