Hey guys, I'm currently running the Windows 7 Release Candidate x64, build 7100. It's been going great and I love it, but just today I seem to have run into some problems. Yesterday, it was fine, today though problems have appeared out of nowhere. The main problems that appeared were: 1. Total inability to sign into MSN, it will either come up with error message 8100030d or 80048820, depending on its mood. Now though, its reached the point where it will sign in if I retry it several times in a row. 2. I keep constantly recieving "Bad Request" errors when I'm browsing through the internet. Many sites will take a reload or two before loading and even then, may load incorrectly, not to mention some pages occasionally come up with a plain old page %ot found or something similar. 3. ALOT on troublsiwith hitmail, when I try to sign in it will usually play the page not found card at me. I've tested the browsing problems in both Google Chrome and IE8, and tested the logging into MSN with both MSN and Pidgen. Also I went to the other computer in the next room on the same network, and none of these problems are apparent. I ran a full scan with Microsoft Security Essentials (which took well over an hour) but that only turned up trojan type thing that didn't actually the at all. Please I don't want to have to do another reformat! I've got 24 gigs of music to move, 22 games to reinstall and then probably near a hundred applications!!!! If it helps, here are all my most necessary specs: W7 Build 7100 x64 C2D 2.6GHZ OC@3.0GHZ Asus P5KR Mobo Corsair RAM Microsoft Security Essentials Interode internet plan Anymore questions welcome, I would be ever greatful to anyone who could help me with these problems! I've got too much school work to worrie about to have to reformat argh!!!
