PC cleanup

[FriedPet]

I cleaned my pc this morning: removing a few big things, blowing all the dust out with my wife's hairdryer I also removed the CPU's fan and heatsink, and cleaned it.
Bought some thermal paste, cleaned the surfaces, applied paste (mini-pea size) refitted everything, waited about 30minutes and turned my pc back on. It's working fine, but it beeped frequently for about 5 minutes.
It is quiet now. Should I worry?

Does it beep after every reboot?

What is the frequency of the beeps? Are they spaced 1 second apart?

I don't know. Only turned it on once after my cleaning spree. It beeped almost every second, could've been longer.

But it stopped now, after about 5 minutes. PC still working fine

Any way you could try restarting it so we can see if it does it again?

Yeah, depending on the BIOS/Motherboard make, different POST beeps are code for different things so the number of beeps and length of beeps and gaps are important, even if its a "continuous beep forever" it has a meaning behind it. 99% of the time its usually RAM related, in which case the fix is just to reseat them and be on your way.

if you removed your ram did you put them back in the same slots, also when it beeps does it post anything
