Need help with Windows 7 installation

Hi

I have been struguling with my PC for 4 days now. I have tryed almost every kinda of installation. I started using a Disk with Windows 7 on and at my current attempt i am trying to install it from an usb stick. My installation have been stuck on 'Completing installation' for 6 hours now. The dots are still moving. I did do a clean install i reformated the disk and deleted the prior partiton from the other installs.

How long do i have to wait for it to pass this step? (it has restarted once.)

Windows 7 normally installs very quickly. The fact it is hanging might mean a driver problem, or it can't get some part of the install completed. It has done the same thing with all the install attempts?

What was on the drive before? Have you tried disconnecting any devices you can?

i have unplugged my 1tb harddisk so only my 640gb harddisk is left for the install. And i did a full clean on both the disk both reformat and deleted and create a new partition

Sounds like your medis sorce is corrupted. Try download an ISO and burning it and then install from that, using your product key.

Download Windows 7 ISO (Official 32-bit and 64-bit Direct Download Links) « My Digital Life

That is where i got my iso from

What was the burn time....the X4, x8, x16...When burning, especially an ISO make sure that it's set to burn at it's lowest rate. The ISO can get corrupted, something happens and it doesn't take much to get corrupted....It happened to me when making an ISO of Windows 8 PR...I had to burn it a second time at the 4x rate and the install went flawlessly. It does happen. Good luck.

I used the USB installation method so i haven't burnt it just copied the files from the iso over to the disk

IF, you decide to break off the install. Prior to rebooting, remove the flash drive. It is not needed after the first reboot.

If the system will not reboot, use the Install media to go into the Repair scenario and try doing a Startup Repair. Maybe it will fix something. Or try booting into Safe Mode using the F8 key to check the drivers or allow something to install that might be having a problem.

If you decide to do a complete new install, you might try cleaning the drive first. When you get to the second page, after you pick a language, you can use Shift+F10 to open a command prompt. From there you can use Diskpart to completely clean the drive. But if you are using an Upgrade version of the Install software, it might cause a problem later with activation.

From the same command window mentioned above, you might check the link below to see if you can recover some of the logs mentioned. Scanning those might give you a clue, and you would normally look near the bottom for any error messages, or a place where the time seems to keep going with nothing happening. The setupapi.log, I believe, is the most useful.

Windows 7, Windows Server 2008 R2, and Windows Vista setup log file locations

If i try to go into safe mode everytime it's the CLASSPNP.SYS error and i reformated the drives everytime i had to start over
+ was using an usb stick

Reformatting a drive is not the same thing as cleaning, but it doesn't look like that is the problem.

Are there any devices listed in the bios you can disable, like BlueTooth or some other motherboard device?

Do you have a printer plugged in that might have memory card slots? Maybe even disconnect the network.
