my sister's computer (p4 with windows xp 32bit)
the above pc started acting weird a few weeks ago, and by weird i mean taking forever to load something the other times taking no time at all and then the time kept changing. At the same time emitting a slight smell.
i opened the pc up and noticed dust clogging the cpu and the fans.
i cleaned the dust out removed the heat sink and put new thermal paste taking care to ground my self.
the next day when i turned it on the motherboard didn't make the beep its supposed to and only the fans including the stock heat sinks were working.
note* while no beeping sound was heard i did hear some weird noises coming from the pc.
i reset the BIOS to try and fix the time problem and that worked.
after few restarts the pc loaded and worked fine for ten minutes then it crashed. i restarted then a very strong smell coming from the psu flooded the room.
is my only likely problem a burnt out psu, is there more to it?
is it worth getting a new psu on a fairly old computer?
thanks for taking your time to read about my problem xD
