I have installed Windows 7 RC a few weeks ago. Everything was working perfectly, in fact, I was pleasantly surprised. Then, a few days ago, I got home to find the machine with the blue screen. The problem appeared to have been minidump, which instantly reminded me of a similar problem I had with Vista on my old laptop where I found out that the cause was incompatible graphics card driver...thing is, up until now, there was nothing wrong with Win 7 nor the driver and I'm thinking, if it was the driver, it would have started as soon as I installed it...so I'm somewhat confused. Today, I got the same blue screen in the middle of my typing. I tried to disable BIOS memory options like it suggested, but could not reach them as they were greyed out. What can be done? The current machine with Windows 7 is HP Pavilion Slimline s3431 with Dell monitor (too old to find a driver compatible with even Vista). Also, I have had a Linux partition before I installed Windows 7 (I dual booted Vista with it) and after Win 7 installation, the boot menu has disappeared and I can't get into my Linux. I tried installing a bootloader but it's not finding the system, even though I am 100% certain I have not wiped it off. How can I get to Linux partition again? Thanks.
