i have been given a computer by a friend,which had stopped working and i have replaced the motherboard because it started powering it self on with out pressing the button and the psu (because smelt of smoke) and a processor and now i have done that there was no display at first and no post beeps.so i changed the graphics card and rechecked all the connections and then booted it back up. then i had one long beep so replaced the ram stick and then i did get a display put wouldnt go passed the post screen so changed the connections again and that all the cards was seated right. then i got to the the start computer normal screen so i thought be on the safe side and start in safe mode and then it loaded loads of files and it stopped on the same file for 3 hours so done a soft boot and then no display like before and no post beep. so checked all the connections and that. when i got the bios screen after rebooting 12 times i set all setting to default and that didnt work.
processor-intel pent 4
motherboard-unkown but has a code on P4XFA???
ram-just 64mb sdr dont want to blow anymore
graphics-geforce fx5200 128mb
hard drive-80gb
