I'm trying to fix a HP laptop for a friend. IM's working fine, and Windows can update itself, but IE and FF refused to work (The pages can not be displayed). I have tried uninstall all networking devices, reset winsock catalog, but still no luck. I tried nslookup and pinging in cmd, and both of them worked just fine, so it's not the DNS problem. I triple-check all the proxies setting and it's NOT using any proxies. I tested on 3 modems, with 2 different ISP providers and the results are the same. I ran Malwarebyte and it didn't detect anything. Any suggestions? I have no ideas what else to do .
