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
=====================
I had posted the above query on windows/desktop section of the forum, i was told to repost it here.
 
I have given my cpu cabinet to a local computer repair shop as i do not have spare parts to test various components of the system.
 
The computer guy told me that there was a issue with BIOS chip and he had replaced it and now it has began to boot properly.
But it is unable to load windows so he suggested to re install it. I told him to format C drive (where old windows 7 is installed) and install new windows on it. He was unable to format that particular device to dynamic feature of hard drive disk. Now he wants to do total format of device in order to install new windows.
 
I had already partitioned this hard drive into 4 drives before and now its causing issue to format just one partition. why?
 
Somehow i was unable to attach a snapshot of gigabyte mother, where i marked with black border, inside which a black coloured square shaped chip is there. He told me that he had replaced a chip which was beneath that square chip to make the system boot. He also pointed out that there is some issue with my graphic card as it was not giving any display out on connecting it to monitor. He is no able to see boot screen with direct connection to motherboard. Here is the link to that snapshot: https://ibb.co/hkN37F
 
Is it true that there is chip beneath that black square thing?
 
Can i revive my graphic card? If not what should be my alternate option for new graphic card which would support current config?
 
I'm sorry for the long post.
 
Please reply as soon as possible.
 
Thanks again.

I would replace the CMOS battery with a new one...then enter the BIOS, reset the date/time, choose default settings and see if things go better.

The technician got the display back, updated BIOS and replaced old CMOS battery. The Blue BIOS screen is still coming once a while and the restart problem still exists. Shall i try shorting BIOS 1 on MOBO like shown in this video https://www.youtube.com/watch?v=QXDOiXHwBeI? Please recommend alternate motherboard and graphic card for my current config.

Please download MiniToolBox  , save it to your desktop and run it.
 
Checkmark the following checkboxes:
  List last 10 Event Viewer log
  List Installed Programs
  List Users, Partitions and Memory size.
 
Click Go and paste the content into your next post.
 
Also...please Publish a Snapshot using Speccy taking care to post the link of the snapshot in your next post.

   Go to Piriform's website, and download the free version on the left.  Click Download from Piriform.com (the FileHippo link requires an extra click). Or if you want to use a portable version of Speccy (which doesn't require installation), click the builds page link and download the portable version. You will now be asked where you want to save the file. The best place to put it is the Desktop, as it will be easy to find later.

    After the file finishes downloading, you are ready to run Speccy. If you downloaded the installer, simply double-click on it and follow the prompts until installation is complete. If you downloaded the portable version, you will need to unzip it before use. Right-click the ZIP file and click Extract all. Click Next. Open up the extracted folder and double-click on Speccy.
 
     Once inside Speccy, it will look similar to this (with your computer's specifications, of course):
 
post-33068-0-86653600-1480692866_thumb.j

     Now, at the top, click File > Publish Snapshot.

     Click Yes > then Copy to Clipboard

Now, once you are back in the forum topic you are posting in, click the ADD REPLY or REPLY TO THIS TOPIC button. Right-click in the empty space of the Reply box and click Paste. Then, click Add Reply below the Reply box.
