BSOD after upgrading RAM

Hi,

I recently upgraded to Windows 7 64bit from Windows Vista 32bit. My computer, SONY VGC-LT18E All-in-One Desktop, came pre-installed with two 1GB DDR2 - 667MHz; I bought two 2GB DDR2 - 667MHz. I already returned once because it could have been an issue with the packaging and scanners at post office.

However, this came packed very well and when I install the new sticks, it gives me the BSOD.

How can I diagnose this issue?

The memory dump found in "C:\Windows\Minidump\" is the first place to look for the dump file as well as taking notes on the error code displayed on the BSOD(dreaded "Blue Screen Of Death") for futher reference as looking up just what the error code is pointing at.

A fast look at the memory dump file created Nirsoft has a nice little freebie called BlueScreenView which will display the information contained in the memory dump file. If the new memory is the correct type and speed and wasn't mixed with the 1gb of OEM memory you are likely dealing with a device driver problem more then anything else.

Can you give us the make, model, and part number of the new 2X2GB RAM?
Will it boot up with one 2GB ram card installed?

Check for the memory dump files where Night Hawk mentioned in the above post.
If there are none then follow these instructions to enable them.

To ensure minidumps are enabled:

* Go to Start, in the Search Box type: sysdm.cpl, press Enter.
* Under the Advanced tab, click on the Startup and Recovery Settings... button.
* Ensure that Automatically restart is unchecked.
* Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
* Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
* OK your way out.
* Reboot if changes have been made.

If they are in the location mentioned above then follow these instructions and post the information requested.
Blue Screen of Death (BSOD) Posting Instructions
When posting a new crash dump, include all System File Collection and health reports. They contain valuable information that we can use to find the cause of the crashes.

I purchased the Memory from GB Ram Technologies on Ebay.
2GB DDR-II 667Mhz
A06520C 101100

It will crash before it boots.

**FYI** I am still missing drivers on my install and have been extremely unsuccessful in locating and updating** It could be a bios issue but I don't know.
I am running Windows 7 x64 Original install from factory is Windows Vista 32bit, this came preinstalled on the system.
I bought this computer back in 2007. I just installed Windows 7 x64 a month ago and have only had a tremendous amount of problems.

I can see two possible and likely factors for the BSODs and any other problems you are running into. 1) You bought the wrong type of memory despite getting the correct speed. That would be installing performance memory on a portable that only takes standard ram.

2) When deciding to switch from the 32bit anything to the 64bit 7 did you first look to see if the manufacturer's support site offered 64bit support for at least the 64bit Vista? If that model only saw the 32bit Windows for some reason finding the correct drivers will be a hunt around the web!

Does it still run with the original 2X1GB RAM installed?

The CPU appears to be 64bit capable.
Intel® Core™2 Duo Processor T7500
Didn't find much info on the Sony site.
The 64bit drivers may be hard to find, as Night Hawk mentioned.

On a good number of OEM machines(desktops and laptops alike) the memory used is referred to as Standard memory. If you went out and bought performance/gaming type memory generally seeing faster timings, different voltage requirements the laptop wouldn't run right to start with. Generally manufacturers will specify the memory type on the product specifications as well as memory supported list.

The blue screens however can have any number of causes most often device driver if not system file related. If you are trying to run the laptop with some mismatched drivers or something saw a bad install that can end up seeing BSODs.

The first thing usually required at a support site when going to download any drivers available is the OS selector for which Windows version as well as whether it is 32bit or 64bit. The onboard graphics would be listed among the rest for whichever version and kernel you are running provided the 64bit sees support.

In other words if that model only saw support for the 32bit Vista Home Premium it came with since each model series typically sees a fast turnover for some newer line you would want to verify 64bit drivers are available. Most 64bit Vista drivers fortunately will work on 7 as well.

The key to solving this however besides going to the support site to see if they have the drivers needed is what is shown on any blue screen as far the error code(s) and any memory dump files created. That will point out the hardware or software problem you are seeing.

I recently went through a series of OS freeze ups when having 7 as a boot option in the Windows 8 Release Preview boot options which resulted in the "ntoskimi.exe" problem without blue screens however. First 8 locked up solid before you could even do anything like open a browser window.

Then due to booting into 7 from the 8 boot option 7 also started locking up with a fresh install of 7 having just been put on! With 7 however a run of the DiskCheck tool was able to clear up the ntoskmi.exe problem in one shot!

In the report you ended up with the readyboost and netboost drivers are trying to load into system reserved memory addresses. Installing the wrong driver set for a few things can also bring on the blue screens unfortunately. This is why the error code info on any BSOD is also a large help at times in debugging things.

With a look at the screen you added in I would have to say the 7 install or some of it didn't go on so well and why you are running into the blue screen wonders! You can try a run of "chkdsk /r" as well as running the System File Checker "sfc /scannow" at the Start>Run command or open a command prompt to see if these will clean it up for you.

But you might still end up needing to start over. You'll know once the blue screens are gone how well the programs run afterwards. If things are bit draggy and programs start hanging up to easily the clean install will be needed again!

One main reason would likely be due to only having reformatted the original OEM C primary rather then seeing it nuked off the drive entirely to see a brand new 7 primary replace it. Reformatted OEM primaries never seem to see good clean installs of any version for some reason. Even reinstalling Vista on a Vista laptop recently ran into the same headaches as far as not running well.
