I have an asus motherboard P5GZ-MX.It has one ide connector and 4 sata connectors.My old sata hard disk used to work well until it got damaged with power failure in our area.Then I bought a new hard disk WD 500 GB caviar green.The seller installed my Linux OS on his computer and gave it to me.But when I tried to boot it on my computer it just hangs at bios and nothing happens.Its name does appear in bios but it just hangs the bios and gives me no option to change bios settings. I updated my bios to latest version,but nothing changes.I tried hd on another mobo,it works great.I had that mobo for an year and this mobo was in my friend's PC.Last week I had to return his mobo back and the problem haunts me again.It was just a temporary solution.Now I must find a solution to this or buy a new mobo.I cannot buy a new mobo as it is working fine.Moreover I have not enough money at this time to upgrade my pc.Please help me.Don't suggest me to buy new hardware.I have an 60 GB wd ide hard disk,I can use that if it helps.
