Hello, I have an asus cg5270. About a month ago I noticed that I couldn't always boot into my hard drive. It would be successful sometimes, other times not so much. Basically it would time out, and the "post" would take a long time. Naturally, I assumed that the hard drive was starting to go and I bought two new hard drives (one being a kingston SSD, the other being a normal HDD from western digital)

So my hard drives come in the mail, and I goto install my operating system of choice (Kubuntu Linux) and while I'm running the installer, the operating system successfully noticed the SDD (it also reported the correct size of the drive), so I assumed I would be good to go, I installed it and rebooted only to find that its not detecting my hard drive (yes I did switch it over to ahci). I even loaded puppy linux (live environment; ran entirely off of a USB drive and ram) to find that it does in fact mount the ssd hard drive.

So I tried using my fresh standard HDD instead, same thing, I boot into the installer, it recognizes it (it also reported the correct size of the drive), installed it and I switched it back to IDE mode (and I was able to "see" the hard drive in my BIOS, though it did not report the correct size), and it says something to the effect of primary hard drive error or something like that. I even loaded puppy linux to find that it does in fact mount the hard drive.

I'm thinking my Sata cable is bad, but I don't know. I don't know much about computer hardware. I thought this would be an easy fix but I don't have any idea how to trouble shoot hardware without running up a big bill.

Can anyone help me figure it out?

I should probably also point out that occasionally (though rare) if I have a bootable usb drive inserted the bios doesnt seem to catch it. Its like a race condition or something. I dont know though

Does anyone think that it could be the power supply?
