Hi bro. Dont worry. Just follow these steps:
- Unplug your AC cable
- Remove your Graphic Card and put it to another Slot
- No need to remove battery
- Press and Hold the CMOS button for approx. 5 secs
- Plug your AC cable and then turn your computer on
I also experienced the same problem once, and it work just like this i listed above.
Hope to work for you too.
