Windows 7: trouble installing windows 7, extremly slow

trouble installing windows 7, extremly slow

Hi, i've just built a second computer from an old computer and some parts. It's been a few years since i last built a computer but i'm fairly certain they are compatable. I tried to install windows 7 on it 2 days ago and i've still not managed to complete an install.
The first attempt took 8 hours fo the install to get to the "completing installation" step, sat there for about an hour before going to bed, when i got up the pc had turned itself off and when i started it i was getting an error

"The computer restarted unexpectedly or encountered and unexpected error. Windows installation cannot proceed. To install Windows, click "OK" to restart the computer, and the restart installation."

after some searching found a post about editing the registery to continue the install. i tried this, set up continued but after an hour went to a black screen with a cursor and never changed.

Second attempt - reformated the drive and started a fresh install. took 11 hours to get to the part where you set the network and date/time ect. Was running so slowly that it was taking 6 seconds to change the years i.e. 2009 to 2010. And took 11 mins to switch between each page and was like it wasn't clearing the old page first. I could see the page about entering a username under the boxes for entering a password

It's now been sitting on the blueish windows image ( the one with the swirly lines and vine thingy ) for an hour. i have a white arrow cursor that i can move but nothing else.

The install disk is fine, i used it to install on my other computer 2 days ago and it took about 45 mins total. i'm fairly certain all the parts are fine, memory and hard drives came out a working computer 2 days ago.

I've searched and found things about changing a bios setting to ahci but i dont have that, only thing that looks similar is a. setting to change between raid and sata2.

I'm at a loss what else to do

Windows takes 15 minutes to install from start to desktop, where did you get this disc from ?

Is it retail ?

Set the bios to default settings and try again.

Back up your files, unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, set SATA controller to AHCI, Hard Drive first to boot, Save changes and Exit.

If you notice UEFI Boot choices in BIOS Boot Priority menu then proceed with UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with. If you don't want a UEFI install you can Bypass UEFI to Install WIn7. This video can help you decide: UEFI BIOS vs. Legacy BIOS - YouTube

Then boot into Windows 7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here. I would use a fresh ISO written with tool in Step 2 as yours is in question.

At first installer screen Press Shift + F10, or enter System Recovery Options to open a Command Box, type:

DISKPART
LIST DISK
SELECT DISK 0 (after confirming Windows 7 target HD #)
CLEAN
CREATE PARTITION PRIMARY
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT
EXIT

Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt. You are creating the partition here for the purpose of wiping the HD and marking Active which overcomes certain install failures.
