1st post...thanks for allowing me to share my issue.
Installed a new hard drive into my HP a6750f desktop with an MSI MS-7548 (Aspen) motherboard. Upon powering up machine, I get no screen response. It does the power self-check or whatever and doesn't continue enough to even activate the monitor. Powering off & on the monitor just says No Input Detected. I've tried BOTH my aftermarket GeForce VGA and the onboard VGA ports to no avail. No BIOS screen...no anything screen.
Power is indeed up. I swapped to an old PS/2 keyboard to see if I could trigger BIOS via F10 or F1 keys as HP doco says. It flashes the LEDs on it upon first power, but doesn't respond after that (the newer USB keyboard wouldn't even do an LED self-check flash). It won't respond to Num Lock or Caps Lock key with the LEDs after its self check flash. I can hear the drive spinning. I can open both my optical drive trays. Fans are operational. Power is a go.
I've tried different combinations of SATA ports -- nothing.
My Windows 7 DVD is ready and waiting to load the OS, but it can never get that far. Maybe it is and it forgot how to display it -- I wouldnt know because I see nothing (again, from either VGA).
Should I just clear the CMOS? Just got that tip from a Windows server guy at work this morning. Any other diagnostic tips/pointers I should be aware of? Thanks again...
