Hi. I'm using Returnil Home Lux (GOTD offer). Just a few hours ago, my Win7 workstation wouldn't boot up anymore.. A dialog box called "System Startup" pops up every time I reboot the PC, but it couldn't fix the problem. I can still access Command Prompt though. Here are the specs of my PC: Windows 7 Ultimate 6.1.7600.16385 Intel Core 2 Quad Q8200, 2.33MHz (not overclocked) 4GB RAM Please advice for solutions ASAP.
