Z87 extreme4

ODD: Optiarc BD-rom

OS: Windows 7 Pro 64 bit

At the actual configuration has been added a PCI expansion card with 5x usb 2.0 ports.

Booting my pc goes like: (1)general ASrock screen (2)announcement of the revodrive hybrid configuration (3)general ASrock screen (4) ?�startup windows??screen. After this, booting proceeded as fast and as usual as always and I was able to login to the Windows desktop.

No notion was given about the new inserted hardware. The new hardware and the pc worked together fine. I inserted my Cruzer 8 Gb flash drive and was able to copy data on and off the drive.

On second startup there was clearly a problem:

-          At the first stage the general ASrock screen was shown for a long period

-          At stage four the pc went stuck on the ?�Windows startup??screen without showing the 4-colored Windows logo.

I then shut down the pc by pressing the power button for 6 seconds.

After that I wanted to know the all details of the problem. I own a SystemrescueCD 4.5.0 and a UBCD 5.3.0. I first rebooted the computer, inserted SystemrescueCD and pressed the button to enter the boot menu: the pc did not respond to keyboard strokes. First I thought I pressed the button too late because I came at a screen (at stage 4) of the booting process it came clear to me the computer already started from my revodrive hybrid.

To make myself more clear: I got a message that before I was able to start Windows, I had to make a choice. I could either choose ?�repair at startup??or starting the normal Windows mode. No button on my keyboard responded. Only by pressing the power button I could try it again and chose to do so two more times.

Each time I refused to use the reset-button. For a long time already I no longer use that button. When a problem occurs, I usually press the power button. That because for me the use of the reset button raises second thoughts, I rather stay away from. The Wikipedia article about the reset button is not clear to me either. Using the reset button might have solved my problem.

After taking note of the error codes, shown in red on the motherboard, it stops at code ?�b4?? ?�Problem related to USB devices. Please try removing all USB devices??/span>

I also first thought there was a problem with voltages after expanding with a pci usb card (in the right slot). So I removed the pci usb expansion card and also my revodrive hybrid (also from a slot). Wanting to know my pc was still functioning I inserted a live medium ?�Sparkylinux-MATE-2.xx?? This to try playing Mahjong from it.

At first I was able to view (u)EFI on the screen and after that calling the boot menu: both keyboard and mouse pointer now seem to work again. Just before start of the Sparkylinux desktop, statistics about cpu usage and others are shown. Normal cpu usage yields maximum 4%, but now it was 10%. Starting the game Mahjong was not possible and the cpu clearly made not any efforts. I decided to power down the computer and leave it for now.

On my pc a Norton antivirus was installed and a firewall.

Before all this my pc seemed at least slower than intended. This could only be proclaimed upon hardware or programming/code on the hardware level. Eventually I also did some research which makes me think ?�badBIOS, badUSB??or a variant now manifests my pc.
