Pc - Hd connection problem at startup

nipper76

i connected my comp to the TV downstairs and all was fine.

i then moved the HD connection from the comp to my blu ray player as i needed the socket on the TV for the sky box.

since then something weird keeps happening...

if you turn the computer on... it wont do anything. no motherboard beep, not picture, just the fan spinning around.

now if i disconnect the HD from the computer, and start it up... it works fine. i can then plug the HD back in and their will be no issues.
you can restart the comp and it will be fine.

but once the computers been powered down for a while, it wont power up unless you disconnect the HD just for the start up.

Any ideas what could be happening, or ways of not having to do this silly routine.

many thanks

nipper 76. No solution, but I am having similar sorts of issues and blank screens. Worth keeping an eye on my post :- http://forums.moneysavingexpert.com/forumdisplay.php?f=29&order=desc&page=2

You can sometimes get these symptoms if the external HDD has a partition which has a "boot" flag but is not bootable (i.e. has no OS installed on it).

There are several possible solutions, but probably easiest is to use a good partition editor (e.g. GPARTED which you can run as a CD from many Linux LiveCDs) to check for and unset any "boot" flags on the HDD.
