Brand, specs, age, operating system, how quickly it happens, what are you doing when it happens, etc. etc.
I will say this however, heat can be a major cause of this. If it is an older laptop, dust builds up inside of it. I would suggest dong this as a first step. Take a paperclip and carefully put it into the fan hole to prevent it from spinning and than take your air hose and try to blow out the dust that has accumulated on the internal heat sink. Do it from both directions, through exhaust side first and than through the fan side. Obviously do this when the unit is off.

Just got a Gateway (Yea, I know)it is awsome! So what if it is proprietary (SP?) mother board, bought the two year warrenty for $100.00, not a bad deal.... 460+tax and Best Buy, pretty good deal I thought.
I'd rather see a rust bucket on the road, than a garage queen anytime!!
Sorry! I know the feeling when my PC took a dump last winter, freaked me out... put two HD's in it works better after the second one. I'm up and kicking but now..... DO you get the blue screen of death? OR the LT won't boot-up?

Crashing is usually caused by things such as hard drive failure, chip/memory problems, operating system failures, spyware/adware, virus/infection, etc...
If it won't boot up at all, find the original program discs, and run everything offline/safemode, to try and get it back to a good restore point. Restore points are various date/time restoration backups done by the pc.. Im assuming the pc was backed up at different intervals?
If its just periodic crashing... loose connections in the rom chip, memory, ram problems, adware/spyware, overheating issues..etc..
