I bought my Toshiba Satellite A210/A215 laptop about 8 months ago. It suddenly started having problems recently. First, it would suddenly crash without warning, no matter what i did. Then after a while even touching it the wrong way would make it crash. I let it sit for a bit and now when I try to turn it on, the lights will indicate its on and plugged in, but there's nothing appearing on the screen. The fan used to come on but I don't hear it anymore so I figured I have to replace that. Any idea on what's exactly wrong and what needs fixed?

I'd recommend going through this guide as a starter

Suggest you reinstall the hardware. I presume you have all the documentation and have back ups of your files etc. Contact Toshiba as the product is still in warranty
