I stumbled across this forum whilst trying to seek online help with the major problem I am having with my Acer Aspire laptop at the moment. I came across this topic which described almost identical symptoms and errors to what my laptop is experiencing, however I found that the solution at the end (the registry entry zip) did not work for me, which is why I have decided to sign up and start my own topic about it.
Ok, so this is what happens.... the day prior to when all of this started happening, I was having some issues with the laptop - virus/malware related. I also was trying to install AdAware, unsuccessfully - it was coming up with some permission issue and kept automatically uninstalling itself (no idea if its related or not).
Now, when I turn on the laptop, it boots, and reaches the "welcome" screen of Vista. But then it crashes just before (or *just* after) it reaches the desktop, I get a BSoD (IRQL_not_less_or_equal) it automatically reboots. This happens every time it tries to boot up in normal mode. The laptop WILL boot in safe mode, however for some strange reason, the keyboard and touchpad are completely unresponsive during this mode. I have to borrow the mouse from my husband's desktop in order to be able to navigate around on it.
I have tried quite a few things to try and resolve the problem: Memtests (all of which passed 100%), Windows back-up/recovery mode (only one state to fall back to, and it did nothing), scans, registry repairs, driver scans... also downloaded and tried the Windows Vista repair disk, to no avail.
I'm truly at wit's end, please help Your assistance will be my last resort before I take my laptop to be professionally fixed - something I can't really afford to do at the moment.
