What are your computer specs?

and i have to reload everything

Reload from what? Where did the media come from? Is this a recovery disk or a shiny hologram filled disk from Microsoft.

As previously mentioned your system specs would help along with your operating system.

   Seriously, I would need more info too, try and let us know what OS you are using, and what the size of your hard drive and ram is... not in inches but in Megabytes (MB) and Gigabytes(GB)...

Cheers

Please tell us what happens in detail when you shut your machine down. Does it shut down normally?

When you start your machine do you have anything in the CD or DVD drive? What do you see on the screen when you start your machine?

well if i shut it down any way, restart it or otherwise it normally shuts down like it should. when i turn it back on i get a black screen saying missing operating system. doesnt change if i have anything in the drive aswell

Computer under warranty?

[alaw37]

no

Go to your hard drive manufacturer web site, and download free diagnostic tool. I suspect, there is something wrong with your HD.

I suspect, there is something wrong with your HD.

Definitely agree with Broni on this. Sounds like the MBR (Master Boot Record) can't be read or is getting lost.

Do you know the make and model of your hard drive?

Also do you have more than one hard drive in the machine?
