I go to boot up my system this morning, and after the initial Dell welcome screen pops up, the screen goes black. However, I can hear Windows starting like normal. The computer seems to be running perfectly fine, except for the black screen. So, I restarted the system, with the same result. Dell screen, then black screen. I tried this several times with the same result.
Having little experience with computer troubleshooting, I took a chance and disconnected my laptop from it's wireless internet connections and power cords and took the computer itself in the other room. This is where things get interesting. Everything started and ran perfectly fine. I left my system on for the entire day with no issues whatsoever. Then, hoping the mystery problem was resolved, I turned the computer off a few hours ago. To my dismay, the problem returned. I got a black screen on start-up. However, once I disconnected everything again and started the system in the other room, everything ran perfectly normal.
I have to say that I'm at a loss here. Any ideas or suggestions would be appreciated. As of now, I'm planning on leaving my system on and not turning it off. I've run CC Cleaner and McAfee's disk cleaner, thinking that the system was being slowed by excessive junk. I have Core Temp, and the temperature readings were around 150 F earlier, which is a little high. Maybe its a cooling issue? If this is the problem, wouldn't the system have shut off at some point during the day? Why would the computer start in one room and not the other? If anything, my other room is warmer than the computer room.
Again, any advice/ideas would be appreciated. Thank you!
