A few months ago i had a series of troubles with my pc, which ended up in changing my power supply to a moderately cheap one, but which supplied the wattage it was supposed to, and changing my motherboard from a MSI MS-6758 to a smaller ASRock P4i65H with most of the former motherboard's capabilities.
The computer worked fine for a while, until it started doing something strange. Only sometimes, when i turn it on, you can hear all the fans starting up, but after a second they stop completely, it stays silent for 3-4 seconds, and then it starts up again.
This only happens sometimes, and only when i power up the computer. At the time i thought it was something about the power supply. Eventually, it did break down, as in it's fan stopped working, so i bought a Thermaltake 450W. But even after this, it still continues to stall on occasion when it boots up.
I am at a loss as to what could be malfunctioning. Any help is highly appreciated.
