after installing ATI 5770 my computer makes 3 popping at start. My comp.pops then my dvd drive starts to spin then second pop,drive starts to spin then third pop then drive starts to spin then computer starts as normal...Also, just like the model 4650 I just installed prior to the 5770,right after start my usb keyboard and
usb mouse did not work.I had to connect them with older adapters.(non usb)

Note: after the initial symtoms I described above the computer works and sounds normal for hours of use!
Temp stays at 45 celcius...
I also notice something else at startup,the fan surges for a split after I hit power on, then normal!

What is the size of your PSU? It really sounds like a lack of power.

Ware is all the fanboys now? Ha!

This is one of the strangest things I have ever heard and I have read a lot of stories. What model is your psu?

That power supply should be big enough for support a 5770. Have your tried putting the old card back in and seeing if you still get the "pops?"

bad PCIE slot is most likely the issue
or just bad power to the board

I think its the PSU, Solytech is perhaps the worst OEM out there.

I have no doubt that it is the psu and I have never heard of that brand before. Popping sounds are a warning sign of ongoing failure most likely electrical arching or thermal expansion.

When you first power on, the gpu bios does a self check, a diagnostic. It also powers the fan@100% for a moment, thats normal.
