what attachment?


and I presume drives means drivers eg the lan and video.

If you cannot get a boot to BIOS or to the Windows 7 DVD it is unlikely that the problem can be solved by way of help on an online forum.

The evidence tends to suggest a power circuit or regretfully a motherboard or processor fault
If the latop is one on which the hard drive can be easily removed from either the hard drive caddy on a slide out drawer or from a panel on the base, I would try that and see if it posts without the hard drive in.

It is a long shot and I do not hold out a lot of hope
When you installed windows 7 did you then enter BIOS and make any changes there.
If so that may be the cause if it was never rebooted until the failure after the changes.

I wish you the best of luck.
