USB + PS2 ports not working. No keyboard or mouse.
Posted on 2009-04-08
Hello there, I have a problem with a PC of mine. I think it might be the PSU 5v rail, although I'm not entirely sure.
When I plug a USB mouse and keyboard in and boot up - none of them power up. When I try a Ps2 mouse, again it seems to have not power. At present the PC is dead. However, on the back of the PC the Ethernet cable has power, ie the communcation light, connection light have power.
The PC is question was infected with a nasty virus that ruined the OS by infecting each and every .exe, so I'm just trying to do a fresh reinstall.
But, I say this is strange because I have had PSU's that have gone "Bang", or indeed some that have start smoking - but never had a particular raid (5v) go. could this be the cause, I cannot think of anything else. I reset the BIOS.
