I was building a PC for my friend. We were on a tight budget so bought most parts second hand. I tested the board and other components before hand and they worked fine. I installed windows so it was ready after we built the PC. After putting the PC together the day after we booted it up. It posted and passed the bios screen. When windows was loading with its swirl the PC turn off without warning. I smelt a burning smell. I looked closely and could see that it came from a capacitor or transformer to the left side of the socket. I don't know if it is the power supply of the motherboard that is broken and I need to buy new parts for him soon. The motherboard is an Intel® Desktop Board DH61BE and the power supply is a Raidmax Cobra RX-600AE 600W 80Plus Gold. I need some help please not sure how to go about testing parts. My other friend has the same socket so could test the CPU with him but how could I test is the power supply is out putting the correct voltages. Or is it just the motherboard is old and I need to get another one and it will be ok. We built it in the garage btw with concrete floors and an anti static wrist band that was grounded to the case and power supply. I have the same brand power supply but in 500W and has been fine. Thanks for any help.

1. This was the initial problem - "a Raidmax Cobra RX-600AE"

2. This is the result - "I looked closely and could see that it came from a capacitor or transformer to the left side of the socket."
What socket? Something on the motherboard? That needs to be replaced as well as the PSU.

Raidmax units are some of the worst PSUs you can buy. I simple wouldn't trust it. I could have just been a faulty motherboard but you said you had tested it so Im assuming it worked with a known good motherboard. My guess would be it overvolted and fried the motherboard.

Thanks for the fast replies. The socket is LGA1155. Do you think the RAM, CPU, HDD will be salvageable? I will get in contact with the PSU people and try get a refund. Shall I replace the entire motherboard or try replace the part on it? Can u recommend a $100ish power supply in New Zealand Dollar. Maybe off the site price spy. Thanks.

I sent the power supply back to the supplier and he is testing it to see if it over volted. I gave the CPU to a friend with the same socket and he said it is running at 80-90 degrees in windows idling and is thermal throttling down to 1ghz. So the chip must be broken? I have tested the RAM and HDD and both working fine. Thanks for the help so far. I asu,e the CPU is past it? Thanks
