Need help with computer shit

How hard is it to reconnect a new HD?

Smash the shit out of your computer and buy a new one

Get new HDD, open your case, find the HDD, take it out, put new one in(make sure to re-plug the SATA cables), re-install windows.

But first, I recommend replacing the SATA cable. Your cable could just be messed up.

I need a new one any takers

how much does sata cables cost? and is replacing a HD that simple, meaning a 5 year old can do it?

and im only 80% sure my HD is fried, not detected in bios and

Yep, it's that easy.

A SATA Cable will cost no more than 5 bucks. One is about a dollar at my local computer store. Also if you do plan on replacing the HDD don't forget attach the cable from the power supply to it . Pretty much whatever wires you removed from the old one, put them on the new one.

what do i look for when purchasing a new HD i dont need one bigger than 650 GB, kinda limited on money soo around how much would a good cheap HD cost?

anyways so i replace the HD install my OS and drivers and shit right?
