Default Unable to turn off pc without unplugging

I read through the sticked posts, and used the search option to see if I could find a solution first before making a topic but to no avail. Although I came across the opposite of my situation where their is no POST, or the PC does not turn on.

I returned to find a blank monitor and the HDD light on the front of my PC blinking sporadically. Also no period of pressing or holding the power button would turn off or restart the system. I ended up having to unplug the power supply to shut it down. Whenever I plug the power supply in again I am met with the same issue. No screen a continuously blinking HDD light and the inability to turn off or restart using the power button. Case, Video Card, and Heat sink fans are still being powered/operating.

New components I have added in the past 3 months are:

-Kingston 512mb ram
-Gecube ATI Radeon 9250 PCI
-Western Digital 160gb HDD

So far I have tried this and started system up again:

-Removing new ram installed. (Same results)
-Disconnecting IDE cables to optical devices and FDD (Same results)
-Disconnecting power and IDE cables to Hard Drives (Same results)

Additional information that may be useful is that for the past month at least once every week to two weeks my computer would make a single beep. I took this as nothing since this was not during start up and felt it did not signify anything. Also for the past month about once a week my monitor would go blank for a second then return back to the desktop.

Emachine T2385:

Phoneix Bios (I think)
Bestec 250 watt power supply
Gecube 9250 ATI Radeon
Western Digital 160 HDD
Western Digital 80 HDD
Kingston 512 ram
Crucial 512 ram
P4 Northwood Celeron 2.30

Having a similar problem also, but my power button is and has always been only for turning the PC ON anyway.
My thread: BSOD - Urgent!!
One option is to try another graphics/video card, thats my next step, also try to replace battery on MB, I have seen that mentioned in another thread.
Please post any results.

Sounds very much like a graphics card problem. Is the fan on the GPU working?
HAF 932 -- ASUS P8Z68-V
Intel i5 @ 4.5Ghz -- CoolerMaster Hyper 212 Plus
8GB Corsair Vengeance Jet Black 1600MHz -- 2x XFX ATi Radeon HD 6970 2GB
