Hi all. I want to first of all say thank you in advance. I've worked as a PC tech for the last year and a half at a local joint here in College Station, TX and BC has been a wonderful resource in the past for me. To date, I haven't needed to ask questions directly; unfortunately, this latest one has stumped me. I have done my best to peruse the forum for previous topics of this nature and have found nothing. I realize it's a pain to answer the same thing twice so please feel free to redirect me if you found something I didn't.
Unlike most problems for which I've sought help on BC, this one is personal. I'm trying to reinstall Windows 7 on my laptop but I'm running into some problems. First, I've run MEMTEST and HDD checks and everything checks out. Second, the full OS installation history was (OEM) 32-bit Vista, 32-bit Windows 7, and 64-bit Windows 7 (currently, or more appropriately formerly as I've already reformatted the hard drive).
I'd like to install Windows x86 on this machine as I've recently purchased a new performance laptop on which I have x64 Win7 installed. Before you protest, the laptop I'm asking about only has 2 GB RAM so there's no point in having x64 installed (and in fact it causes a lot of compatibility problems for legacy programs; yes, I installed Virtual Machine w/ XP but the graphics card doesn't carry over so I can't run the programs I need). Unfortunately, every time I try to boot to the DVD with Win7 x86 on it, it loads the files, shows the "Starting Windows..." splash screen, and then BSODs. The error? "c000021a"
I've put a x64 Win7 disc in and it doesn't have this error at all. Any idea what might be causing this? I'm emarrassed to ask since I should know these things as a tech but I'm at my wits end here. Google hasn't been kind to me and I'm about ready to give up. Any help you can offer would be awesome. Thanks a lot guys and gals!
PS. Please let me know if you require any more information.
