I have a computer that someone built to my specs which he did. But it seems that he knows nothing about pc's cause it worked for one week and then started to go crazy in to many ways to list . My question is why cant i put a differant os on my pc , i have windows 98/first edition on it now.I have tryed to fix it along with severl other friends that know lots bout pc's. We all failed to put diff os on it , or find out what the problem is . Also when i use any usb port it freazes windows os cold .My specs for the pc is amd duron 800mhz , 256mb added mem , 20gb harddrive , voodoo3 gravfics card , one cd rom , and one cd rw rom. Any help will be apreciated .
