I am currently bringing and old custom built computer of mine back to life and so far I have hit several walls. First one is my new 160 GB SATA hard drive that my computer wont recognize, i have already brought it to a local computer repair shop and had a friend there check it for me, he formatted it for me and said it was working just fine. My computer will read another SATA drive with no problem. My second problem is from another older hard drive that i put in and tryed to install windows xp on. The installation gets about 50 % of the way through and then turns itself off and starts beeping (even after I have unplugged the power completely from the back of it. I am ready to pull my hair out, can anyone please help?
