|"I put the speaker in, forgot about it......"|
If you mean the case speaker, or the equivalent, in that case, the tests you did before that where you got no beeps need to be done again.
"got 1 long beep and 3 short ones."
That usually indicates a video problem - in this case, a video card is not installed in a slot, or it is installed, but it has a problem.
- unplug the computer or otherwise switch off the AC to the case. You should do that AT ALL TIMES when fiddling with connecting or disconnecting any connection or component inside the case !! ATX mboards are always powered in some places even when the computer is not running !
- make sure the video card is all the way down in it's slot
- some PCI-E video cards have a socket on them that must have a wiring connector from the power supply plugged into them.
All new mboards these days have two power sockets that need to have connectorsf rom the power supply plugged into them - the main 20 or 24 "pin" one, and a smaller one.
Restore the AC power.
Try to boot.
If you still get 1 long beep and 3 short ones, you have probably fried the video card, and/or the PCI-E slot's circuits, yourself.
"I noticed my PSU was not compatible with my GPU because it was only 500w but i needed 550. so i put my 9800gtx+, same thing happens. "
Whatever gpu you were using orginally should have worked anyway, at least before the specific drivers were installed for it. The minimum capacity being only 50 watts less than the minimum recomended for the gpu should have still allowed the gpu to work - but you can run into trouble eventually because the PS is running at 100% or it's capacity much of the time the computer is running when the card is installed.
Generally PSs are not designed to run at 100% of their capacity all the time, and doing that will damage the PS.
When you're a gamer.....
In most if not all cases, the max capacity rating of the PS is an intermittant rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should get.
If you get no beeps or a different beep pattern other than one beep or 1 long beep and 3 short ones while the computer is booting...........
then you may have installed ram that is incompatible with using it in your mboard, or it has a connection problem.
Remove the AC power to the case/power supply.
Remove all the ram.
Restore AC power.
Try to boot.
If nothing else is wrong, you will get no video but you will hear a pattern of beeps that indicate no ram is installed, or a ram problem.
E.g. for an Award bios or a bios based on one, that's often a beep of about a half second, silence for a half second, a beep of about a half second, silence for a half second, continuously.
