Hi
Welcome to Tech Support Guy

I am NOT quite certain what this means would you please explain

).all i did was install windows 7 and all drives;

I think I am right in saying that the laptop orignally came with Vista or XP but not with 7.
How have you installed 7 please
From where did you obtain 7 and in respect of

the light gos out

power led or HDD led please

The unit came with vista and i installed windows 7. the operating system is oem and purchased at compusa.
I installed as the the instruction indicated, also formatted hard drive with windows system.i had to install lan driver and also i up-dated the video and graphic drives. It will not even boot to the bios screen,when you push the power button the light comes on and gos out; in about 10 seconds the light comes back on and then gos out. that is want happens, did you get the attachment

did you get the attachment

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.

thank you for your time; i also think it is the motherboard.
