Windows 7: System refuses to boot after memory upgrade

The graphics card probably will need to be removed. I had that problem once. They go in and out easier than memory in most cases.

-Simply unscrew the mechanism that locks the jacks plate in place and most will just pull out.
-Some mobos will need for you to press down on similar locks like at the ends of the memory modules.
-Make sure the memory is seated properly with the tabs locked in the upright position on the memory modules.
-Replace the graphics card in the reverse order of steps you used to take it out. It will be recognized automatically by the computer like the memory should be.

If the tabs are not fully up, the memory might not be seated properly even if you apply a lot of pressure, because they will usually lever the memory modules up and out when pressed down. Make sure you try to stay in touch with the case to avoid static discharges that can ocassionally damage the memory and other electronics. Always unplug from the outlet.

Thanks for this, much appreciated. The more I think about it, the more I think it could be that the graphics card prevented the tabs from working correctly, and what you say gives me more confidence that this might be the issue. I'll remove the graphics card and try again with the memory modules before replacing the graphics card again - I'll give this a try in a few hours (late night now here in the UK and time for bed!).

OK, I've made some progress with this, and at least it seems all my hardware is working properly:

- I removed the graphics card and reseated the four memory modules; this time, the process was much easier as I had more space to get access, and the clips were able to clip down and back up again without hitting the graphics card.

- Put everything back together, but still no boot up or access to BIOS.

- Removed the battery to reset the CMOS, still no dice.

- Found that my motherboard has a 'back to BIOS' button. Pressed that and it booted up to BIOS - yay! Checked all the settings (bearing in mind my limited knowledge here) and was able to confirm that the new 16GB memory was recognised by the system (although it's at 1333MhZ rather than the 1600MhZ it should be capable of running at, but I can look into that later).

- Exited the BIOS and Windows started to boot... Until it stopped dead.

I've repeatedly tried using the Windows Startup Recovery tool that automatically launches at this point, but it's been "unable to find a solution to the problem". Everything launches as per normal, but once it gets to the Windows loading screen (swirly blobs that form the Win7 logo) it freezes, then powers off. I also tried reverting to a recent restore point: didn't think it would work, and sadly it didn't.

I'm starting to think that the next course of action will have to be using system restore from a system image I have on an external hard drive. (fairly recent, but I think I'll subsequently need to install a couple of recent applications). I have my data backed up, so won't lose any files. Do you think this is a good course of action, or are there alternatives that I could try out?

You haven't listed your system specs in your profile, but just for good measure, I would make sure the new memory is compatable with the board according to the Intel (mobo) website before you restore from a backup copy. You can also try to "Repair Windows" from the system disk if you have it.

-Boot to BIOS and make sure your cd/dvd drive is first bootable drive.
-Place Windows system disk in drive save settings and reboot.
-Windows will load from the disk and you will have an option at the bottom left to "Repair Windows"
-Select "Repair Windows" and I think the option is system restore on the next screeen.
-Just make sure you don't reinstall Windows yet.
-This option will not affect your personal files.

You say you do get a normal POST, though, right? Usually a single short beep. If you do, and have exausted the first two options, then you may need to go ahead and do a system restore from your backup (which will affect some of your more recent files) because it is some other problem.

If none of those work, then a fresh install of the OS may need to be done. It is a good thing that you have an external, recent backup of your files, you will be able to restore them after a fresh install of the OS if necessary.

Hope this helps.

Thanks again.

Yes, I'm now getting past POST, something I wasn't able to do until this morning. The backtoBIOS button allowed me to do so - bit odd really.

The memory is compatible according to the Corsair website. The Intel information supplied for the motherboard doesn't list these specific modules as tested, but it's a bit out of date now; however, the general information at the top of the relevant page does match the specs listed by Corsair. So there seem to be no issues there.

Unfortunately I don't have the original Windows DVD: my PC was a custom build by a company called Novatech over here in the UK and they pre-installed Windows as part of the build. I sometimes think I should have just installed it myself and got the disk...

As i said though. I do have a fairly recent system image available on an EHD, so it looks as though I may need to go down that route.

I did just try to disable the automatic shutdown when Windoes detects a problem, resulting in a blue screen with the following code: 0x00000007B. Not sure if that means anything to you? I've searched for the code online and there seems to be a wide variety of causes and solutions.

Issue has been resolved!

Just to update, I've fixed this problem and am now up an running with 16GB. To say I'm pleased about this is something of an understatement!

I did some research into the BSOD error code, and it relates to Windows not being able to identify the disc partion to load the OS from (in my terminology anyway). I spent some time checking the BIOS and noticed that it was set to IDE for the SATA controller. Based on some of the information I've read through today (a lot) I decided to try changing this to AHCI... And Windows booted up. I did reset the BIOS (as well as clearing the CMOS, which I would imagine would reset it anyway?) and the company who built my PC must have opted for AHCI. The reset obvioulsy changed that to a default IDE setting.

Thanks ever so much to all who offered up their help and assistance, especially Chrisb647100. You helped me to work through this issue and come to a positive outcome. (Always been impressed by the folks and information on this forum (I'm a long time lurker), and my opinion is now even higher.)
