it certainly seems likely that its a physical problem. there is no easy test to work out which part exactly is the problem, but obviously since it happened after transportation it seems likely that something has moved. just the heat or cold of it being in the trunk will not have affected it, its the movement that has caused the problem.. unless your trunk leaks and it rained lolyou did say the computer makes noise didnt you? the fans run etc.. just no beeping noises? this probably rules out the power supply.the ram in this case is the most likely culprit, as the computer wont post at all. if it was a connector to a hard drive or something like that then the computer would probably post but not find a hard drive. you could try removing the RAM card/cards first, making sure the slots and ram are nice and clean, and putting them back in. Do NOT attempt to clean the RAM cards with anything but compressed air. You can buy cans of compressed air at electronics shops, a handy thing to have to perform the regular cleaning that computers really should get anyway.If that doesnt work, all i can suggest for now is that you dissassemble the computer as far as you are confident in doing, give it all a good clean with compressed air, and reassemble it with special care making sure everything is fitting snugly and correctly.Once you have done that, if it still wont post, then you have a problem. Something isnt working properly and you will need a techie to physically test. If you want to avoid a techie, you could experiment by buying some new RAM as I still think its the most likely culprit and its reasonably cheap to buy. After that, you could replace the CPU, the motherboard etc, but as they cost a lot more it would be better to get a techie to check it out before spending any more cash.
