Here is the thing . I did see the same problem around here . I got two PC's one quite powerfull with win xp and it runs quite well now I still got my old system P III 500 256 MB SDRAM ( 2x 128 ) AGP Voodoo 3 3000 NIC 40 GIG HDD CD/DVD ROM this one is for going online only - the system on this one is 98se Software 98 se DSL Provider Software Flash GET IE 5.5 thats it. Now the problem - not always but too many times the machine reboots itself - usually I can leave the machine on for hours and actually surf for hours without anything bad but when I download things ( sometimes one item only , sometimes more than one ) bang - reboot . does anybody here got some sort of Idea or way of narrowing down the problem ? Sorry about the hassle .
