PC getting stuck at the Intel boot screen

Question

there is this strange problem I am facing for quite a while now at the time of starting up my pc.

WHERE it occurs: The problem occurs at the very first screen that appears after pressing power button where there are two ‘Intel’ logos with few two digit alphabets which keep on changing at the right bottom of the screen like: BA BC EB usually this screen last for 2, 3 seconds.

WHEN it occurs: BUT at the times when the problem occurs my PC remain stuck at this screen at the BA point (see image attached), with no CPU activity happening it just remain stagnant there.

Other Important Observations/Information:

• This problem ALWAYS occurs when I Restart my PC or even when I Shutdown and start it again without switching off main power (UPS + Main switch)

• I have also noticed when I have a bootable USB attached to PC at the time of booting up it gets stuck at the BC point instead of BA

• To correct it I have power it off, switch off electric supply behind including UPS, Main power, wait for 3,4 seconds and power it on again, than it all works fine.

• I have changed my power supply for the PC as thinking that this issues is somehow related to power problem but didn’t helped, I have also reinstalled windows after this problem but this problem is still there.

• PC configuration: 64 bit system | Intel Core 2 Quad Q8200 | 4 GB Ram |

• Screen shot of screen where PC gets stuck

Kindly help me out with how to get rid of this problem as it gets really problematic in many ways including while installing windows or when you have to restart your pc etc.

Thankyou!

Solution

These POST codes stads for:

BA - Detecting presence of a removable media (IDE, CD-ROM detection, etc.)
BC - Enabling/configuring a removable media

If you don't need boot from USB devices. I would try to enable "USB Optimization" at UEFI configuration.

1. At that Intel start screen after power on press F2
2. Then in UEFI configuration go to Boot tab
3. Enable USB Optimization
4. Press F10 and accept with Y

Which usb devices are connected to your computer?

I wonder if the UPS is connected via USB!

I think UPS wouln't be detected as removable device. I would bet on keyboard or mouse.

@Dave Rook: No UPS isnot connected through USB. Its just directly going into the power supply.

@week Thankyou for explaning codes but I cant locate the option of USB Optimization in my boot menu inside intel setup tab, there is USB boot but no USB Optimization. can you giude me a lil more.

Devices connected to system through USB includes: Keyboard & 3 microUsb cables but the microusb cables are usually not connected to any devices at the time of startup.

Have you tried booting with your USBs unplugged, to see if it's caused by usb? Update UEFI from manufacturers site.
