POP and burnt smell

[blackettle]

I recently built a new Core i7 system. I was running a "Verify Disk" function on an onboard raid controller and after about 5 or 10 minutes, I heard a loud POP come from the PC and the PC immediately shot down. I came into the room to investigate and it smelt like something had burned up. I opened up the case and looked around but did not immediately notice anything unusually. I tried booting the machine and it started up just fine. I have since installed Windows and various software with no problems. I am pretty concerned about what it could be and why it would still be running. Any advice is appreciated.

most likely..

PSU

Have you experience anything like that before? I am curious as to why the PSU would still work. Needless to say, it makes me very nervous.

I would take the mobo/other cards out and look around and try to find the part or any black marks. Could be the start of an intermittent probelm that can do more damage....or could be as simple as a loose plug in the wall that sparked/popped on the way out.

I would take a close look around before proceeding, even if it seems fine now.

OK. I took the system apart. I maticulously searched the motherboard for any sign of black marks. I noticed that one of the capacitors has what looks like black "puffy" stuff underneath it. It looks like the stuff just popped out of the underside. It is barely noticable.

Could it be that this capacitor exploded?

Got a pic please?

[SugarJ]

yup, bad cap that exploded. RMA time.

No I do not have a pic. I do not have a camera here to make one or I would. It looks like a matte black substance.. Almost like a charcoal briquette.

If you heard a pop, and now theres a black mark under a capacitor, I would not use the board and I would send it back for rma.
