Okay, so yesterday, my brother tried to move my computer downstairs to the basement. When he tried to start it up, it did not show anything on the monitor. It seems to power up fine, but cannot display anything. I've already switched out the video card, which yields the same result: no signal to the monitor. My CPU has the big Zalman 7000 heatsink, so I'm thinking that some rough handling may have cracked something on the motherboard, or maybe the chip. If anybody has anymore techniques to rule out components, or can just diagnose the situation, I'd appreciate it.
this happened to me once when i had one of those massive aero things that looked like a jet engine.. With mine it cracked the mobo. Other things it could be: Loose ram/cards: Pull em all out, give em a blast of air and plug back in. loose something else: check power cables and other things.
obviously check everything is in properyly, things might have worked loose. Does the internal speaker make any beeps? these beeps can be used to diagnose the problem, check your motherboard manual to see what they mean. Also depending on your motherboard, you may have some LEDs or a numerical display to tell you if anything is wrong, these would be on the motherboard itself or on a backplate so check for that too. the zalman 7000 heatsink should be fine to be honest, i have a 7700 and its survived a few car journeys edit: and welcome to the forums
The motherboard isn't making any beeps for me. And now that I think of it, something similar happened after a car journey with this computer. Except that time, it magically fixed itself. I'm going now to recheck everything. edit: Still no indication that anything is happening. The hard drives are spinning up, but just for a second, not long enough to load anything. So, I'm pretty sure it's the mother board.
Woo! I just realized that I had a DIMM that wasn't in the computer at the time of the incident, so I swapped it in and... it started up! Thanks for your help guys, I was already looking for new parts.
