Computer not turning on properly

[trunten]

When I turn on my computer it does one of four things.

1. It turns on normally
2. It turns on, but no data goes to the monitor and justs sits there with the busy light on.
3. Turns on with two long beeps, but still no data going to the monitor.
4. Turns on with 1 long beep, 2/3 short beeps. I've checked the video card and everything is fine, at least it seems like it.

I'm not sure whats wrong. The video card's red light (error) isn't turning on and the green light is always on.

My opinion I would reseat the memory, possibly it is not seated properly when cold, and after if warms a little it makes good contact. Reseating processor wouldn't hurt either

That didn't work, or I probably didn't seat it right again. I don't know if its the seating of anything. My computer's been working with no problems and I didn't open it at all for the past 3 months.

trunten,
Brianf is correct, try this

One Beep to Three Beeps
One beep = refresh error, two beeps = parity error, and three beeps = base 64k memory error. For all three error codes:
1. Try taking out your RAM sticks and reseating them.
2. If that does not fix the problem and you have more than one bank of RAM, take out the first bank of RAM and move the second bank of RAM to the first bank's slot (leave the first bank of RAM out and then power up your PC to test it) -you may have a bad SIMM or DIMM. If the RAM you had in bank two works fine in bank one's slot, then the RAM that was in bank one is bad.
3. If both solutions fail, replace your motherboard.
