I've recently bought a Dell Inspiron 660 running Windows 8 which has been working well. However, in the last week, it's been randomly switching to just a black screen and no keys / mouse etc have any effect. The only solution is to reboot, which works.

I bought dell XPS L502x with Intel centrino wireless N 1000 a year ago. I havn't had any problem with the wifi until the last 3 months. I get access to internet but it's slow and sometimes doesn't open websites. I have another computer that works perfectly with the same router.

for inspiron 15 3521-8275 bios is flashed to a06, i have tried the latest driver from dell site, version 9.2.0.504, installation is okay, but i can not connect to any access point. is there any wireless driver for windows7 64 bit that is actually working? thanx in advance, dejan
