I have been having alot of problems with this PC for along time such as RAM slot fails sometimes and causes Hang to the system, on-board LAN slot hangs and causes system to hang & always hanging for no reason but lately the on-board sound started having this weird noise like VER LOUD high pitch static sounds non stop like a bomb is going to explode and then now I can't get the pc to run windows more than 5mins because it will just hang.. I have tried removing every single thing CONNECTED to the mobo and put them back 1 by 1 it all work fine for the first few mins but after that it just hangs then i decide to check the ATX12/24 connector and found out 2 pins was burned.
My question is what is the cause of that 2 pins to burn?

Sorry for my bad English.









Hi

Thanks for the clear picture 

there is 3 failed capacitors on the power supply closet to the 3.3v connector. which could be the cause of the memory problem.

When a connection BURNS like that it is normally because of something like cleaner or dirt on the power supply plug if it was making a good connection there should be no heat so no burning.

Have a happy day

Lisamaree   OK so i will get a new PSU and test it againHi


You missed that the capacitors are faulty on the power supply and that WOULD be causing the memory errors.

A new power supply isn't going to fix that.

Either replace the capacitors or the motherboard.
  Also

It seems strange that an IBM computer would have those capacitors fail. Unless you can replace the capacitors it could be quite difficult to locate a replacement board.
