YOU NEED TO REINSTALL THE OS

try finding a used dvd drive on ebay.

Does it boot to the windows screen. By pressing f12 or f2 whatever your machine requires while booting will take you into the bios. Inside the bios you can run all sorts of tests to see what the problem is.

Before you start thinking about your motherboard, let's rule out your harddrive.

Go online and Google "emergency boot cd" and choose a product that works for you. Many have "demos" you can use with limited capability, but that's fine. You will need to take the .iso file and burn a CD with it. This will create a bootable CD.

You will need to setup the computer to boot from a CD by going into BIOS and setting the boot sequence to CD first. If you don't know how to do that, here's a good article...

Using your newly created CD, put it into CD drive and start boot up. If your computer boots normally, you have a harddrive tht has failed. If not, you may have a motherboard issue, or possibly a different hardware issue that may require professional assistance.

Hi

please press DEL to set the bios settings then choose the Bios set up! then click the bootable device SCSI.

Thanks!

reconstructive boot, you mean, like a recovery boot? you'll need a recovery disk.

Sounds like you are getting a supply line issue which is well known on these models. Pull the battery, Boot into BIOS, (F10 at the splash screen) And see if it will run for an extended period of time. Next if it does Boot into Safe mode and do the same..(This is F8).. Post back..
