Recently had a motherboard "fry" on me. I'm not sure the fault, but let me explain:
System:
Phenom 555, OC'd to 3.6 on standard voltage.
Asus M488TD-V Evo USB 3.0
16 GB Patriot Viper 1600 MHz (board read it at 1333 native, but it was advertised at 1600, so that's what I set it to)
OCZ Vertex 4
Seagate Barracuda 1.5T
Radeon HD 4850
Nexus NX-5000 PSU: 500W (some aren't familiar, but is recommended by SPCR).
Going Down:
working away at some coding, suddenly hear some "crunching", and within 5-ish seconds smell burning. I immediately shut down as fast as possible via the OS. I couldnt quickly reach the power cord, but within 30 seconds I had it unplugged and then opened the case. I saw one chip fried: turning brown and all bumpy, down toward the bottom of the board by the USB headers and Front panel connections. Looking at the manual, I determined it was the Parallel ATA controller, to which nothing is hooked up.
I'm suspicious of the PSU only because why would a chip fry under zero load?
Earlier that day, I had two USB sticks die, as in they are no longer recognized on any system. I had blamed it on the age of the sticks: I had difficulties in the past with these drives (taking forever to write, not actually writing), but now I'm thinking it could be related, though all other usb devices (keyboard, mouse, NIC) are all working well.
I haven't tried powering the machine back on for fear of fire or further damage. I did pull my drives, video card and memory, all tested fine.
I pulled and tested the PSU, and all the voltages are within spec:
12V: 12.08V (allowable 11.4 to 12.6)
-12V: -11.89V (allowable -13.2 to -10.8)
5V: 5.15V (allowable is 4.75 to 5.25)
3.3V: 3.44V (allowable is 3.14 to 3.46)
5VSB: 4.96V
Only the 3.3 is close to the max allowable.
I looked for AC on the DC lines, got 1.3-1.5 mV (.0015 V) on all voltages.
By all tests I've found, It should be good.
I don't want to replace it for the simple fact its super quiet, but I don't want to fry another board, either.
Thanks
