I'm having a problem booting my computer. I noticed some slowdown problems recently, but the other day my computer would not start. I received an error message that one of my .sys files was missing or corrupted and that I should put my windows system disk in, and then press "r" to repair on the first screen. The error directions were awfully vague. (Sorry I don't have the exact .sys filename, I'm not at my home computer right now but I could get it pretty quickly).
Then, when turned the computer off and back on again, it would say windows did not boot properly, would you like to go into safe mode, regular mode, etc. No matter which one I picked, it didn't boot up. So I went to bed, it was pretty late. I woke up the next morning and the computer worked fine. I was even able to restart it more than once.
Now today, the computer does not work again. Moreover, I only get the error message sometimes. Other times it just gives me a blank screen when the initial windows screen should come on (after all the memory check, etc.), and I never receive the safe-mode option screen.
I suspect this to be a virus because after my computer malfunctioned, I used my external hard drive on another computer, and then that computer experienced rapid slow-down problems. My friend scanned his computer, and found he had a virus that transmits via external hard drives.
Someone please help me soon, I have some critical work I need to do on this computer.
Thank you very much,
