(SOLVED) BSOD on installing zte data card Ac2739.

<< < (3/8) > >>

Boggin:
Doing an offboot sfc /scannow can work in Win 7 when the one run in Windows is unable to repair all files so give this a go.

Your install disk would need to match the current state of the installed Vista - i.e. if it has the SPs then the install disk must be SP2, otherwise you would need to reinstall from scratch, which could fix it anyway.

However, all things being equal, boot up with the install disk and navigate to where you can select Repair your Computer and then onto the Recovery Environment.

Select Command Prompt and enter bcdedit |find "osdevice"

Using whichever partition letter, enter (assuming c) sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows and see what that reports.

Just in case it isn't clear, that's a Pipe symbol before find and there's a space before each forward slash.

Enter exit to close the command window, remove the install disk and Restart.

You could still get the gpedit errors as they aren't native to Vista, so perhaps using a restore point prior to adding those may help - unless it was adding gpedit that has caused the other errors.

To eliminate that, use your restore points to prior adding gpedit and run the sfc /scannow again or a chkdsk /f.

Even once again reinstalling Vista and immediately trying to install the modem in safe mode resulted in the same old BSOD. It looked more and more likely that Vista is messing up things. Having struggled with this for a month, I decided enough is enough, and installed Windows 7, which had no problem in installing the modem even in regular mode.

I'd like to record my heartfelt gratitude to Shane, Boggin and Heyroxie for taking the time and effort to help me out.

I had posted this problem at http://www.vistax64.com/crashes-debugging/303557-bsod-installing-zte-data-card-ac2739.html some weeks back. The thread has had more than 1700 views, whish shows the keen interest this problem has created. I'll post there and give a link to this thread, so that more people come to know about this place and utilize it.

Regarding memory non-detection problem, in the absence of other explanations, we can attribute it to the very old BIOS, and leave it at that.

Thank you once again, one and all.

Regards, 
Rama.

Boggin:
I think that was a good decision  :cheesy:

Thank you Boggin.

I posted at the other forum immediately after posting here, but that post has been removed, and I didn't get any messages. Being a Vista forum, may be they were reluctant to let it be known how Vista failed, and there was no help.

I noticed a curious thing about the memory . In Vista, like I said, the Max Memory box won't go above  800 something, and in Windows 7 it won't go above 1024. May be somebody has an insight into this.

Regards,
Rama.

Boggin:
I don't have a max memory option in my Win 7 msconfig and thought from the Google I'd found, that this was just a Vista thing.

Some forums won't allow references to other forums threads and is probably why your post was removed - have you checked their forum's T&Cs ?
