buy n install ,if i forgot my mobo model how do i check
thanks in advance for ur help
1. Under $90 for a consumer 500 GB HDD. Most motherboards
support SATA, but check for compatibility just in case. Download
CPU-Z, run it, and go to the Mainboard tab. Google the model
number, and the first result should lead you to the manufacturer's
website with details of your motherboard. Look for a download link
for a document regarding technical specifications, go through it
and look for the word "SATA". If you see that, then it's
supported.

Be warned that it would be slower than booting from a local HDD
due to bandwidth limitations of USB 2.0. How much slower?
Approximately twice to thrice the loading time; probably sluggish
during normal usage. Generally not recommended. You may want to use
Linux-based Live CDs instead.

As for the prob of not being able to see your HDD in My
Computer, try looking for it in Control Panel > Computer
Management > Storage > Disk Management. If you don't see it
in the list of HDDs there, it's likely dead. Do note that there's a
possibility that the HDD is working fine, but either the connectors
or the data cable is not, of which case you could just replace the
entire external casing. How to determine that? You'll need to
borrow a working external casing to test with.
3. Same advice as #1. Look for the technical specs detailed on
the manufacturer's website. Take note of 4 things:
I. The maximum amount of memory your motherboard can
support.
II. The number of memory slots your motherboard has.
III. The type of memory modules it supports (whether it's DDR, DDR2
or DDR3).
IV. The maximum amount of memory your OS supports (refer to link
below).
If you're going for a slightly better performance, also take
note of whether your motherboard supports dual-channel memory, in
which case you would require 2 identical memory modules for it to
function.
