strange power on behavior

[metallicafan]

I helped a friend of mine swap out his AMD 3200+ and motherboard for a Pentium D 2.8Ghz and an Intel motherboard. We put in a new motherboard, CPU and heatsink, and new memory and left everything else in the system as is. Everything works and everything turns on fine but when you plug the power cord into the electrical outlet all of his fan LEDs blink on and the turn off right away. This never happened with his old AMD board. Any ideas on what may be causing this? Just kinda worries me.

Yes, your friend owns a piece of shit power supply that skimped on capacitors. Nothing bad....just a cheap PSU. The coolmax PSU in my little brothers systems does that, but all the enermax's ive owned never did that.

so its not hurting anything then huh? a better power supply would probably fix the blinking?

Why did it only do this with the Intel chip and motherboard?
