I recently noticed the cpu and gpu temps going nearly 100 degrees celsius so I thought I might needed to replace the paste that was on the GPU and CPU. Once I took everything apart and put it back together, my laptop boots a black screen. The Hard Drive and power leds are on but for some reason my DVD drive doesn't make that sound when I power up my computer. Then 15-30 seconds later, my fans started to spin fast than normally over and over again. I have no clue what could lead to this. So what could be the issue?
