keyboard and mouse not plugged in?
i cant see what's going on with the monitor, cause most of the time u pointed the camera at the machine...
the monitor nothing come out. the cpu keep repeating on and off
Try putting the ram into other slots. Also, use an eraser to clean the golden contacts of ur ram.
Are all of ur hdd/ssd connected? Do remove all hdd/sdd except for the drive containing the OS.
still can not
any idea i can backup the hdd?
U need a working laptop/desktop to transfer all data files at least.... Or u meant backup the OS?
No beep sound ? You connected your speaker ?
i have a normal desktop computer, i need backup some files in the hdd, not OS
Then, connect the sata data/power cables to that HDD and backup lor.. Have to do the manual way.
i've tried, the pc say i don have permission to go in, since all the files is inside the desktop, not D drive
Ok wait, just to clear things up. How many drives u have in ur problematic desktop? Which hdd/ssd have the data that u want to back up?
No such thing as 'inside' desktop, its either in C drive or D drive. U can still plug in ur OS C drive into ur other com. Just make sure in the BIOS, it is not set to as 1st priority. Or u can plug in the data cable when ur other desktop is up and running.
only one hdd in my problematic desktop.
all the file want to back up is in the C drive's user's desktop
i connect the problematic pc's hdd to another computer. i can access to its D drive only. but when i click in C drive's user folder, it say no permission.
ericccc your CPU cooler is very dusty causing the CPU to overheat , the power is cut off for protection against damage . check the thermal paste also.
You need to take ownership of the drive, use the link below to guide you step by step:

Add "Take Ownership" to Explorer Right-Click Menu in Win 7, 8 or Vista
That's the link you could use. Works on Windows 8 too.
