I'm having a bit of trouble with a GIGABYTE GA-MA78G-DS3H (rev. 2.0) motherboard. Recently when trying to clean my AMD Phenom II X 4 CPU, I dropped it and broke some pins.

I have now brought a Athlon 64 X2 5400+. However, it does not seem to work.

To begin with, I cleared the CMOS via the jumper located near the battery. This was because I had my AMD Phenom II overclocked and did not wish for the same voltage to go to the new CPU.

I then tried booting with the monitor plugged into the chipsets VGA but no luck.

No signal was sent to the monitor, and the monitor just went into standby. I then tried it off the graphics card but the same happened again. Then I tried to check whether the CPU could executed some BIOS codes by stripping the RAM out and making sure a speaker was plugged in but no beeps could be heard. I replaced the speaker and tried again but no luck.

The CPU is brand-new so what is going wrong?

disparity between `top`'s given CPU % and process CPU usage total

I've noticed that there are sometimes (large) differences between the reported total CPU usage and a summation of the per-process CPU utilization given by apps like top and wmtop. As an example: I recently ran a git filter-branch --index-filter on a fairly large repo, with the index-filter command… >>> More
