My computer believes that it is connected to a local area network (at 100.0 Mbps), but no packages are being transferred, and no programs are able to access the internet. I tried a network repair, which resulted in an error claiming that it was unable to query my TCP/IP settings. I tried a system restore, many times from different dates, but no settings were changed as it was unable to restore to any system restore points. I tried running IPCONFIG, but 'an internal error occurred' as 'the request is not supported', and it was 'unable to query the host name'. I tried right-clicking 'install' on nettcpip.inf, didn't work. I tried refreshing my TCP/IP settings, didn't work. I checked my network card, but it claims to be working properly. What could this be?
Oh, and my computer has slowed to a crawl gradually during the past 4 months or so. It now takes minutes to highlight, press, and open the Start menu. Makes fixing it all the more difficult, not to mention any programs I wish to run. I have tried getting more RAM, cutting my graphics' quality, cleaned and de-fragged my hard drive many times, removed any and all programs that I don't use on a regular basis, cleaned my registry, made sure I'm using NTFS, and attempted to optimize performance. None of this has seemed to speed up my computer, and its reaction time continues to lengthen. I don't know what else to try...
Could somebody please help me?
