Hello to everybody. I have been reading this forum a while now but did not have an accound and an active participation. But that will change I guess.
I have the following problem:
When I start the system, my keyboard and mouse are not being recognized from the system. At first, I could get into BIOS and Ubuntu but not on Windows. Now, I can not even load a cd so that I can format my pc because my USB keyboard and mouse are not recognizable and not even the leds are lighting. So, they are dead from the very beggining.
I though that the problem was the 8-pin connector that my MB had and the fact that I only connected only 4 pins because my power supply does not have more that 4-pin cable. But, as I read at this forum, the other 4 are only for grounding and better stability of the system.
So, I cannot format, and when the systems enters Windows by itself I am not able to do anything. I tried connecting mouse and keyboard through USB 3.0, USB 2.0 and with a PS/2 converter. It is always the same.
Any suggestions please?
Thanks in advance.
I just bought a MB: Asrock Z87 PRO3
CPU : i5 haswell 4670k
My Power Supply is a 400W Deer and my PC box is a Zalman Z11 plus black. I have a Razer mouse and a X7 keyboard(although it does not matter).
PS:When I did manager to get into BIOS at the very beggining, I supposed that the problem was that I had the legacy USB support enabled.
