Everytime i start up the computer it beeps 3-4 times, and the monitor says vga input not connected...whats could be the problem?


here are the beep codes for your exact dell model. this should give you a starting point on finding out what the problem is.

Beep Codes Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of beeps, called a beep code, identifies a problem. One possible beep code (code 1-3-1) consists of one beep, a burst of three beeps, and then one beep. This beep code tells you that the computer encountered a memory problem.
Reseating the memory modules may fix the beep code errors in the following table. If the problem persists, see "Contacting Dell" in your Owner's Manual for instructions on obtaining technical assistance.
Code
Cause
1-3-1 through 2-4-4
Memory not being properly identified or used
4-3-1
Memory failure above address 0FFFFh

ASRock K7S41 / K7S41GX, sound 3 Beeps 3 times, then power off automatically


I had 3 beeps, pause, 3beeps, pause and so on.

Defective SMD transistor near the ATX power connector. Original is a 2SB1202 (marking B1202).
I bought a 2SB1203 which is stronger and soldered it in. The K7S41GX board runs as fresh as from the dealer.
