I am having problems initially booting up my computer. I first press the start button and the computer comes on however no beep and no boot-up. After pressing the reset button several times, it catches and there's a beep and the computer boots up. Once on, the computer works marvelously. It also shuts down perfectly.
Other times, I press the start button, switch the computer off with the switch on the power supply, put it back on and depress the start button again. I'll do this a couple of times and the computer finally beeps and boots up.
I have replaced the power supply believing it to be the main problem.
I have an Asus A7V Mobo with 800 mhz AMD Duron, 256 meg Crucial SDRam 168 pin PC 133 CL2, 64meg ATI Radeon 7000 Graphic card, Creative Sound Blaster Live Value Sound card, 40 GB Western Digital HDD
Not sure if this is coincidence but I have noticed that after I have used the computer for some time and shut it down - I wait a few minutes and restart the computer and it boots up normally.
