    disk.sys problem during/after install


    I installed Windows 7 on my laptop, an Acer Extensa 4630z. It went painfully slow the first time, took about 3 hours to get through but never gave any error message or stopped completely. But when it restarted the first time it froze at the windows is starting logo. When i booted in safe mode it stopped at disk.sys. I reinstalled windows overnight and about 8 hours later it was installed, rebooted, and running. I thought it might be solved and I restarted the computer just to check. It froze in the same place, at the windows starting logo, still disk.sys in safe mode. I thought it was a hard drive issue so I tried everything I could think of, changing BIOS settings between AHCI and IDE, even tried a completely different hard drive. I've tried removing each stick of RAM individually. I've tried both 32 and 64 bit versions. Nothing works. Please help. At this point i feel like hurling the thing out the window.

    Remove all devices non-essential. Use unit only while plugged into wall socket to install.
    Remove as much system ram as possible while still having a functional unit to install.

    There is nothing else plugged into the computer. Its plugged into the wall but do you mean remove the battery too? It came with 2x1gb sticks of RAM. I've tried it with each stick of RAM individually to no avail.

    Bios on IDE.

    Actually, now that you say...yeah, try removing the battery in case it is malfunctioning.

    Try flashing the BIOS too.

    It's in the middle of yet another install right now. It is set on IDE, only has one stick of RAM in, and seems to be going faster than it has previously but is still pretty slow, about an hour in and only 47% through expanding files. If it doesn't work out this time I'll try flashing the BIOS.

    torrentg, I'm not sure I understand how the battery could cause this. Could you explain that?

    If the battery is malfunctioning, it could cause erratic voltages from unit trying to charge it. Removing the battery is a good way to test and/or solve the potential issue.

    That makes sense, worth a try at least. Its only gone from 47% to 50% in the last half hour. I think it might be time to try something else. The most recent BIOS on the Acer website is called 1.24. I'm not sure which one is on there now because it says revision 3.5 in the BIOS. Also I'm not entirely sure how to go about flashing the BIOS. The download is just a .exe file. Is there a way I can run it from a cd without windows? Sorry if thats a stupid question but I've never had to do this before and don't want to ruin anything.
