can't burn bootloaders (I detailed my problem) #hell #help

hi guys,

i'm writing post because can't manage burn bootloarder on 2 atm chip have.

i have arduino uno rev3 use arduino ide version 1.0.5-r2 on windows vista computer.  tried followings computer has ubuntu , windows 7.
the target chip atmega 328p-pn. don't have external oscillator bootloader use  made 328p  use internal oscillator: http://arduino.cc/en/uploads/tutorial/breadboard.zip.

i plug described in tutorial : http://arduino.cc/en/tutorial/arduinotobreadboard.
meaning join mosi mosi, miso miso, sck sck , pin 10 of arduino master reset pin 1 of target board 328atm. plug 0 , 5 v on both side of target chip , found out have put  little pressure on chip fit breadboard , there 5v on 5v pins example.
also there 10µf between reset of target board , ground , 120 ohms resistor between 5v , same reset pin.
and check delay line in heartbeat function of arduinoisp code delay of 20 ms.

i can send global output in verbose mode of ide think main information :
« avrdude: device signature = 0x000000
avrdude: yikes!  invalid device signature.
         double check connections , try again, or use -f override
         this check."

after error heartbeat keep going , other leds don't light.

i have same error , de device signature same (0x000000) when tried burn bootloader .hex fil through avrdude in terminal.

i have second target board atmega 1284p-pu use 20mhz external oscillator , bootloader reprap project (http://reprap.org/wiki/gen7_arduino_ide_support). can't burn bootloader either.

so know can burn chips or if have nice links send please i'd happy have hint of solution.

thanks in advance.

remove capacictor of reset pin, , change reset resistor bigger 1 (10k).

signature 000 sounds bricked chip.
