Suspected dead motherboard

-CPU fans and system fans spin, but noticeably slower. Without system fans, the CPU fan is barely audible.
-No signal to monitor
-HDD sounds like it's starting UP
-CTF light illuminated on Sapphire 4890
-CPU generates heat. Tested without heat sync on, but only briefly.

What I've done
-Removed the CMOS battery, reinserted 30 minutes later with system off
-Replaced CMOS battery
-Have a single DDR3 RAM card in
-Reapplied thermal paste
-Checked CPU for bent pins
-Have video card out, nothing but bare essentials, using onboard video, DVI/VGA
-Tested PSU with another computer and had it work flawlessly
-Removed everything and reassembled with same results

What I was doing before it broke
-Drove it to a friend's house and had it working there, didn't set it up when I got home
-Plugged in a PATA DVD burner and had it make intense clicking noises with no signal to monitor



AMD Phenom II X4 955 Black Edition Deneb 3.2GHz Socket AM3 125W Quad-Core Processor

G.SKILL 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666)

Sapphire ATI Radeon 4890 1gb DDR5 model

700Watt Cooler Master PSU

Hauppage 150 Capture card

750gbs 6/gbs 7200RPM hard drive

Some Lite-on dvd/cd burner. I don't really know. I hardly ever use CD's anymore.

As for accessories, I have one 23inch monitor and another 19inch. 7 speaker surround sound setup.

Also the Rosewill CHALLENGER Black Gaming ATX Mid Tower Computer Case

There is no post sound, but there never has been. I'm bringing one home from my co-op today as well as a different heat sync.

So dead motherboard? Should I go ahead and RMA it? I've overclocked it in the past, but not anytime in the past couple of months.

  1. even though you tested the PSU in another computer, I would still buy a PSU tester (10.00 bucks) and just be sure that everything co insides with all the specs on your particular system.
