Windows 7 BSOD without any recognized reason

[WojtekK1902]

Hello, I have a problem with BSOD that happens accidentally on my laptop. I have no idea what is the reason, because it happens suddenly and I cannot connect it with any action. I would be happy if anyone could help me. I'm attaching information from W7F, CPU-Z and RAMMon (all in the zipped folder).

Moreover, I have one question - is it normal that CPU-Z shows that Core Speed, Multiplier, Bus Speed, Rated FSB and Core VID on CPU tab are not constant but vary all the time?

Hi,
almost every dmp file is the same.

ewusbwwan.sys Tue May 31 12:41:34 2011: Huawei Technologies Co., Ltd. USB NDIS Miniport Driver. Probably a WiFi Dongle or similar. Try finding later drivers for your device

Thank you for your reply. Yes, it's my LTE modem - Huawei E398. But what should I do if I can't find any driver for this model at the website of Huawei?

Hmm... you could try installing the driver in compatibility mode but its a long shot at best.. Try the driver download here:

Do you think that this site is trustworthy??

Dammit... Sorry about that. I didn't check the download so no don''t use them.

I've checked the above site (Huawei support) and the only have drivers for Macs. Googling didn't find any other drivers either. It could well be that the device is faulty. Can you try it in a different machine and see if it bsods too? If so then you'll know it's the device which is busted and not the driver.

Frankly I don't have any other computer I could use... Well, this BSOD is not frequent, and it started to appear not so long time ago (previously there was no such problem). Maybe I could get used to it.
Anyway, thanks for help.
