Hi,

I was having trouble with my keyboard dying during the middle of using it, so I got frustrated and pulled the power cord while the computer was on. I probably did this 2-4 times because it kept dying. Eventually, the computer wouldn't even boot. It won't boot into bios or anything... all of the lights turn on in the case, fans spin, but no beeps/noise from mobo and all of the usb ports don't get power(for example, usb mouse doesn't get power).

I have done the following:
Re-seat RAM
Re-seat sound card
Re-seat video card
Re-seat CPU/heatsink
Remove CMOS/Power, let sit for a few minutes
Remove all unneeded devices/items(all usb stuff, etc.)
Let computer sit overnight

No avail. What in the hell is the problem?

AMD 64 4000+
nVidia GeForce 7900GTX
2GB Corsair XMS
SeaGate 320GB SATA2 7200RPM x2
Creative X-FI Xtreme Sound Card
Special heatsink
Antec 550W PSU
GigaByte 3D Aurora Case

It sounds like the mo0therboard died.

there is aq slight chance that the power supply went out .
A PSU can appear to work & still be bad.

If you have, or can obtain, a dufferent [known good] power supply try it.
OCZ StealthXstream 700W,Gigabyte GA-EP45-UD3R , E8500, Arctic Freezer Pro 7, 3GB G.Skill PC8500,Gigabyte Radeon HD 4850 OC [1GB ], Seagate 250GB SATA II X2 in RAID 0, Samsung SATA DVD burner.
