Solved Acer aspire 5315 won't reinstall windows 7 after reformat

August 14, 2014 at 11:35:04
Specs: Windows 7, AMD Turion 64
After recently using web root windows washer to reformat a hard drive using the system eraser. I inserted my retail copy of Windows 7 to undergo a clean install but half way through the installation the laptop froze. I therefore restarted the laptop and the windows surprisingly re-commenced and carried on where it had left off. However once the installation had complete the laptop was in a very unstable state whereby if you attempted to open a program you would receive the blue screen of death. So I therefore re - ran the system eraser software to re wipe the hard drive.

Now when I attempt to start the installation it will start up 1st time and get as far as the scrolling bar and states windows files are loading then once this is complete I receive the blue screen again. 1st time I received it I believe it said
IRQL_NOT_LESS_OR_EQUAL

So I again restarted the laptop by pressing and holding the power button as the computer had also froze, after a few attempts of powering up the laptop nothing would happen unless I left it for an hour or 2 (wouldn't matter if left plugged in or unplugged)

After said hour or 2 the computer would start up again, it would do the same as before then display the blue screen, this time it's stating

Memory management error!!

I have wiped hard drives god knows how many times with the same software and never had any problems. I don't understand what's happened, can someone offer any suggestions?? Is it likely to be an issue with the hard drive, memory or even the motherboard. Would a 3rd attempt at the system eraser help? I presume it wouldn't hurt to do it again.

Thanks in advance for any assistance, if you need any further details please ask.

You don't give the reason you reformatted and reinstalled. If your initial issue happened to be due to a hardware fault then obviously formatting and reinstalling the software wouldn't help, although you might now get a different error.

It would be worth removing the RAM and cleaning the edge connectors with a pencil eraser, then pop the sticks in and out a few times to clear any oxide off the sockets. While you are in there do the same for anything with edge connectors, such as the display card (if any). Also ensure all plugs and sockets are pressed firmly home.

If you were trying to install with a hardware fault present you might still have to do it again after you've fixed the hardware because this could have caused a corrupted reinstall.

Always pop back and let us know the outcome - thanks

✔ Best Answer
I would first run Memtest via a bootable CD to test your memory.
No errors are acceptable, though occasionally, cleaning the contacts or correcting BIOS memory settings will solve this. If a retest does not show clean, replace the memory. Memory purchased separately often comes with a lifetime warranty but memory included with a machine carries the warranty of the machine only (a year) but check with the memory mfg..
If the memory is good, test the integrity of the hard drive with the hard drive manufacture's test suite or Seatools from Seagate. If the problems are minor and are not too many, the software will 'repair' the problems but too serious or too numerous, will require replacing the drive.
Wiping the drive should not be needed if the machine was yours and you are keeping it. All that is needed for a clean install is to chose the Custom and Format options during the install, Delete any partitions, create a new partition, Format it to NTFS, and install. A quick format is usually enough, but if you want to write zero's across the drive and have a few hours to kill, then do a full format.

You have to be a little bit crazy to keep you from going insane.

Thanks for your suggestions guys, after swapping the ram with ram from a fully working machine it turns out 1 of the 2 1gb ram cards was faulty causing the whole system to malfunction.

After removing the faulty ram I was able to fully install windows 7
