Hello, I am helping someone to fix his computer. At the moment he has one of those barebone PCs that fail to boot. I suspect a virus of some sort. It's like this: The computer starts to boot Windows XP Home edition fine, the loading screen appears, then the screen goes black as to load the desktop, a mouse appears, a minute passes, and the computer reboots. My first thought was hardware, but the hardware seems in order. My second thought was bootsector, but I loaded the fail safe options and it didn't work. Third option was to start Windows in safe mode, which I tried, it loaded the same black screen but with the usual safe modus words in the corners, then I get an error. lsass.exe tells me I don't have enough qouta to start the computer. Or I get an error API doesnt have enough memory or something along those lines (I am translating the dutch output). So I cannot even get to anything in windows, I am sorta worried here because I am running out of options and we don't want a reinstall on that computer. We could boot with something like Knoppix but that won't fix the Windows issue. Any ideas?
