I have a desktop computer which I put together myself and in the last weeks I discovered a strange behavior.
The same issue refers to three components independently. The onboard network controller, the PCIe sound card, and the intern USB3 upgrade card which is PCIe, too.
The point is that each of those three components either work or not after booting my computer. For example this morning I turned on the computer and USB3 worked, network and sound didn't. Therefore I rebooted and all three components work now. That will stay true as long as the computer is running. After each new start, it seems like a wheel of fortune whether one of those components is working or not.
The drivers are updated for all of those components. Here are my components.
- Operating system: Windows 8 64 bit
- Motherboard: Gigabyte GA 870a UD3
- Processor: AMD Phenom II X6 1055T
- Video card: NVIDIA GeForce GTX 660
- Sound card: Creative X-Fi Xtreme Audio
- USB 3 upgrade card: Sempre UP33-I19
Can you think of a reason for this strange behavior? At the moment I can work fine, but just need several restarts to get all needed components working. How can I narrow the problem down? How to approach such a problem?
