This started after the local cable operator leased out the network to a different ISP. this ISP is worse than the previous one. First, my computer seems extremely sluggish when connected to the net now. even the desktop hangs. i may have found the culprit:- sometimes if i end the process, it will end, but come back again. sometimes, trying to end it will trash the system. mouse and kb will work, along with the start button, but nothing else works. Even Alt+Ctrl+Del shows an error. The appearance changed automatically and its gotten stuck at that. Some elements in the windows like buttons etc, are all square and classic, like in win98. They dont go back to normal, even after restarting, or fiddling with their settings. even applications like CCleaner, IE and opera and and all that i can think of seems to be affected. Even this tab too! the title bar at the top of the window isnt supposed to be there (and other things)! Sometimes after the system has locked up, if i press the reset button, it doesnt work either. Other times, if i long press the power button, the monitor goes off, but the CPU keeps running. Note: this all started after i changed my network settings to match the new ISP, and logged in. before this everything was allright. but during the changeover of the ISP, my comp did get sluggish if the ethernet cable was connected. however it didnt cause any other problems. comp went to normal as soon as i unplugged cable. i tested my HDD, RAM, they are both ok. No viruses, checked with eset, updated. what is going on Oh and i am getting 8mbps download and 2mbps up during speedtest.net to the neighboring country and while download few things like opera, chrome, but other than these i am getting only 50kbps speed!
