Windows 7: Fresh Windows 7 Install on new hard disk, frezze problems

Hi.
I bought new hard drive SATA 250GB WD HD Caviar Blue SATA III 6GB 3.5'' and i install windows 7 on it.
Problem is my computer start very slowly , (there is no programs yet) and very often randomly freezing.
Things i have do and didnt help;
I have checking my memory memtest86+ no problems found.
I reset BIOS
I upgrade BIOS, all drivers.
I borrow RAM STICK from other computer
I Reinstall Windows 7 like 10 times, using other dvd brand , burning by 2x speed or faster

And intresting is computer works faster with one stick ram 2GB THAN two stick ram 2GB but its still freezing alot like every 30 second for 2min~

Please help me, mayby u got some ideas what is wrong.
Btw. sorry for english

Take the hard drive back for another, it`s bad. The fact that it`s new does not mean it`s good.

Take it back, exchange it, reinstall windows on the new hard drive.

The reason i change hard drive was error during installation, new hard drive solved this problem, but i got freezes now. Why u think problem is hard drive? Its new from shop, never used before.

I think it`s the hard drive because it`s freezing, like I said, just because it`s new does not mean it`s good.

A fresh install on a properly working hard drive should never freeze up.

Did you spec this RAM you moved from the other PC? It needs to be the exact spec for the computer you moved it to.

Grecrocker might be right. YOu May need to spec the ram first. Also let me ask you: Do you use an old Sata cable or the one you use is new? I tell you this cause last week I had a problem like yours boot use to takes forever or sometimes was not successful. Every thing changed for good once I switched cables.

Well it should go without saying that all the other parts were working fine as all he did was add a new hard drive to the pc, and it is then that he started having issues.

Im using old Sata cable, unfortunately havent new one, but boot is fine, its randomly freezing sometimes at boots sometimes on desktop, question may be dumb, but how to spec ram ? im using DDR2 goodram 2gb x2

You need to use a Sata3 cable & Sata3 port.

Im afraid i dont have any SATA3 port. What should do i now?
