My Toshiba Satellite A100 - PSAAKL - 00M008 runs on genuine Windows Vista Home Basic - SP2 with auto updates enabled and is up-to-date. Though the system is slow (old model), and the Bios is 2007, there has been no major problem. However, when I tried to install zte data card Ac2739, windows consistently blue screens. I've ascertained that there's no problem with the data card itself. I have done the memory test, checkdisc, and sfc /scannow, but no issues. I've tried to install it in Safe Mode, Clean Boot Mode and with Avast disabled, but no go. Whocrashed says the probable culprit is cdrom.sys, but the installed driver version (2006) is the latest one. I've  disabled the driver and tried to install the data card, but still the same result.
The USB port is ok, since I am using it to access GPRS through my phone.

I ran Driver Verfier for 48 hours continously, but no BSOD.

As a last resort, I re-installed Vista from my OEM disk - with no service packs. Still, the BSOD occurs when I try to install the modem. I think Vista is causing the BSOD by trying to install the wrong drivers. I've tried to prevent Vista from installing drivers by selecting the "do not install drivers" option from "Advanced System Settings - Hardware",but Vista still tries to install drivers, which results in an immediate BSOD. I've got the Reliance Netconnect software with drivers, but Windows is doing its own driver installation and BSODing.

There is another problem, doesn't seem to be related. After the Original 512 MB RAM failed, I've been using a 1 GB RAM in one of the slots. Now, because of the increased load, I've added another 1 GB RAM to the other slot, but both the BIOS and Windows show only 1 GB RAM. I've ascertained that both the sticks and both the slots work fine. Speccy and CPU-z also report 2GB RAM.I couldn't find any update for the bios.

I have uploaded the latest specs and mimidumps.

Any help is appreciated. Thank you.
Rama.
