I have a hp pavillion 8667c. I finally got around to puttin a lil more ram in it. during the process i took everything out of the case. hard drive cd and dvd drives as well and blew everything out with canned air. after installing the new ram and plugging everything back in, the cpu wont start up correctly, it will go to a black screen and say that my cpu was not shut off correctly due to a power failure or something of that nature. it will eventually start up after a period of 27 seconds with the prompt that a fatal error has been corrected by retreiving past log files. after i click "ok" to this message and try to open anything such as an mpg file it will begin to play and then my cpu will automatically restart and boot back up to the prementioned black screen. any insight would be greatly appreciated!
