Ouch! I'm trying to wrap my brain around this one. Maybe I need dope! So, let's start at the beginning. Who built your computer? Homemade or built custom, give us a rundown on it's components-mobo, cpu. and ram size particularly. I really need to know if you have dual boot. In fact, if dual boot is not done correctly all hell can break loose. My neighbor had just that sort of occurrence with an ill configured dual boot. So as I get it to date, you have both XP and Win7, possibly. Here's how to tell. Reboot and watch the process. If you have dual boot, the startup will pause with a black screen and white letters asking to pick Win7 or an earlier version.It will go with the default version if you don't pick, waiting a maximum of 30 seconds, or less if it was shortened as it seems from what the geek did to speed up boot. What also puzzles me is when you got it back from BB, you said you tried to go on the Internet, and couldn't. If no OS is present, you couldn't even try. You will have a blinking cursor on a black screen, maybe saying no os or missing component (missing ntldr or similar). That all means exactly that...no os, therefore you could not be presented with the opportunity to do anything other than shut down. So please fill me in here, and maybe we can get to the bottom. When listing the OS, please also indicate if the Service Packs are installed, and what Anti-virus package is running, if any.
