Untimely System Crashes-Reason?

[ayushsanyal]

Hi Everyone!
I'm a newbie to computers,so when I started getting these 'BSOD''s,I was a bit taken aback. My system is only 6 months old.
I've attached the dump files,but I have no clue why my system crashes. I'm pretty sure its virus -free.

Please help!

P.S-I had removed my laptop's battery once,and due to power cuts,my laptop was shut down while booting ( I've heard that's a bad thing) Is that the cause and if so,please give a solution! (These crashes have started happening since that one time)

Networking errors - and I'd blame the lxu800m.sys driver for your Reliance USB modem
Please download a fresh copy of the Win7 drivers for this device from the manufacturer's website - DON'T USE Vista drivers!!!

Then uninstall the software for the device and remove the device.
Test for further BSOD's
If you don't get any, then install the freshly downloaded software and test for BSOD's again
