Why does my thumbnail turn blue?

Monitor won't turn on, laptop.?

• I own an alienware m17x. A few days ago, I was having trouble with Windows Explorer crashing due to a thumbnail of a video. I managed to delete the video and ended up using System Restore just to make sure everything was ok. Well I left my laptop on all night last night, and I woke up this morning to find it going REALLY slow. So I try to restart, but it locks up in the process, so I kill the power and turn it back on. Now the monitor won't turn on. I know the computer isn't frozen, the keyboard still lights up and I can use the FN button to open my CD tray, and my USB mouse is lighting up. Any ideas?

• Answer:

  Are there any beeping noises when you turn your computer on? If you aren't getting any beeps, the computer isn't even getting to BIOS, which suggests a motherboard problem. Warranty Repair If you can hear a single beep, it means your computer is running fine, which would suggest a display problem. Warranty Repair If you hear multiple beeps, you need to check your manufactures website or the troubleshooting manual that came with your laptop. It could be some hardware component that is causing the problem. Warranty Repair I can't think of anything else off the top of my head. If you have any more questions, you can email me.
