Hi,
 
Whenever i start my computer, i get a blue bios screen with following details:
 
GIGABYTE _ UEFI Dual BIOS (Screen Title)
BIOS has been reset - Please decide how to continue (Dialog or popup title)
Options:
1.Load optimized defaults then boot (by default highlighted)
2.Load optimized defaults then reboot
3.Enter BIOS
 
I have tried all three options, but it keeps poping up on every new boot session.
My computer does not shutdown properly as it restarts the system on clicking shutdown option. I had to switch off from main switch board every time.
After trying all options, when the system shows desktop, in the taskbar few icons are not visible, they will take space on screen but wont be visible.
To make them visible , i have to reboot the system.
Once the reboot is done, icons in task bar becomes visible and the incorrect system time is shown. Sometimes system shuts down randomly. I gave my system to a local computer repair shop, they were able to start the system, but could not find a solution for auto restart. Now my system is not starting as i cannot see the motherboard logo on screen which use to come before.
 
 
My system specs:
 
Motherboard: GIGABYTE GA-B75M-D3H
Processor: Intel i5 (3rd gen may be)
RAM: 8GB ddr3 1600 mhz Corsair Vengeance(4 GB X2)
PSU: VS650 Corsair
Graphic card:HD7850 GDDR5 2GB
 
 
I have 4 usb ports on the front panel of cabinet and 3 at the back panel.
 
Front usb's and audio jack does not work properly, back ones does work well.
 
Please advice me on how to find the root cause for all of these issues and rectify them as soon as possible.
 
Thanks

Have you checked the CMOS battery (a silver thing the size of a US nickel) on the motherboard?
If it's dying, it may not keep the BIOS settings and will revert to the default date/time and settings.

 

Beyond that, I'd suggest posting over in the Internal Hardware forums for some more expert opinions:    http://www.bleepingcomputer.com/forums/f/7/internal-hardware/

I found the solution to this problem, that was to replace the current motherboard with GA-H61M-S and now everything is working fine. Thanks everyone for your suggestions.
