my computer has recently become unstable and I cannot find out why,I recently had to reboot the entire thing and was a pretty painless process but lost a lot of data. If I open My computer the ctrl alt delete keypress tells me that it is not responding.I try to use the internet through explorer 6 and it takes a long while to bring up the connect screen!ofthe several minutes but typing in an address brings it up straight away. I use Norton Systemworks pro 2003 and i installed a programm form on of the cover disks that i didnt like called modem on hold (by ess technology inc.) and later uninstalled it but it still comes up at start up and when i connect to the web. it is not in the startup file and I have no idea if it is causing the slowdown but everything started when I uninstalled it.Norton detects no virus's and i have tried updating internet explorer, to no avail. my computer is high spec so its not struggling with the tasks amd 2600 agb ram fx5200 graphics 120gb hdd all new.
