i have a dell computer that was having problems with turning on if you could get it on it was okay but if it went off it took forever to get back on and hydro went out and i can't get it back up ever since. It runs good once it starts up???

Is this a laptop or a desktop computer? State the model. If it's a desktop computer........ " hydro went out and i can't get it back up ever since." Power spikes or surges, or lightning strikes, experienced during a power failure can damage anything - they frequenty damage the power supply If this is a desktop computer...... Failing power supplies are common and can cause your symptoms. Check your PS. See response 4 in this: http://www.computing.net/hardware/w... ........ Other possible causes...... See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated: http://www.computing.net/hardware/w... For a laptop, you must remove both its main battery and AC adapter before you do that. For a desktop computer..... There may be a poor connection inside your case somewhere. Unplug the case/power supply. Power off your monitor. Open up the case by removing the left panel as seen when you're looking at the front of the case. Check all the connections of the wiring to make sure they are all the way onto their pins and into their sockets, especially the main connector from the power supply. The wires close to the mboard going into the main connector/socket should be more or less perpendicular to the mboard surface rather than at an angle. Make sure all cards in slots are all the way down in their slots. Some Dell cases have a latch you must push one way rather than screws you must remove at the back of the case. While you're in there, if the cpu fan/heatsink has mung (dust, lint, etc.) on it, clean it off, but DO NOT use a vaccuum cleaner to do that - use canned air, or an air nozzle if you have access to an air compressor, or an artist's brush that can be used in small spaces, etc. If may be difficult to clean the top of the heatsink under the cpu fan - the most likely place to have mung on it - and the bottom side of the cpu fan blades unless you remove the fan. If you have a case fan, clean that too if it needs it.
