Thank you. Finally some more people came to help or at least for the guidance. I have sent the laptop to that motherboard repair person again. He would test it for all kinds of errors hopefully. And to Compton, I already had to point out the NFA435 driver to u which I'd already mentioned in my first post. Also if u read my first post, I did say I tried drivers from acer's site. So again, I'm not angry just because I cannot handle my temper or I'm some kind of that type of person who just loses temper and blames people. I was doing all the steps u asked me. And again, as I mentioned in my previous reply to you, I already knew my hard disk and memory was working correctly. But I did it because I wanted to give u all the info as I said. I thought might be...this guy has more deep knowledge so he would read every line of that report and look for something extra. I don't want to diminish anyone's knowledge or value here. But thank you for your time, as you said.
And thank you to LarryTheComputerGuy. Learnt a new term thanks to you and what you said seems to be appropriate. And to Timster, I tried external USB Wifi dongle or whatever they say it and it caused BSOD, too. So, I thought that was the end to trying/ putting new external things (in this case). But yep, WiFi device inside my laptop is the culprit ( or at least seems to be, for now). Would wait for the laptop to come or for any news. Thank you Timster, Larry and Compton
and Britec09 obviously for making them videos. Cheerio
