Re: my monitro wont work and the cpu make a running sound
Most likely your onboard video isn't working. Onboard means it's built into the motherboard. Install the video card you bought at Staples in the correct slot (the box will most likely give you a diagram of the slot configuration) and power it back up. Because you have power but no screen display, it's almost "for sure" the new video card will be the solution. Be sure to plug your cable into the new video card and not the previous display port. Have your installation CD handy to install everything that will give you the most out of your new card. Let me know if you have any further concerns. If that solves it, please rate the answer.

When you say that the CPU doesn't work, what happens exactly? Does it not power on OR There are beep sounds heard OR there is an error on screen that you would like to share? OR ...
Assuming that the machine is not powering on at all .. here are few checks that you would like to perform...
There is a toggle switch (Voltage selector) at the back of the computer on the power supply unit, just besides where you connect the power cable .. make sure that appropriate voltage is selected.
Try connecting the computer to a different wall socket.
If computer is connected through the Surge protector or UPS then try connecting it directly to the wall socket.
Try using a spare power cable if available.
Remove all other connections apart from Power supply, keyboard, mouse and monitor and see if that makes any difference.
Remove the power supply cord from the back of the computer and press and hold the power button for few seconds .. this would drain the accumulated power from the CPU components .. now reconnect the power supply and see if that makes any difference..
Open the chassis and see that couple of wires run from behind the power button on the CPU to the big circuit board (Motherboard) .. make sure that the wires are properly secured.
Perform these basic checks and let me know and I would glad to assist you further.
I would try to power off the machine completely and hold a key down on the keyboard and power on the computer while still holding down one key. Keep holding it (it might make an irritating beep sound, that is expected) . This is one trick that will almost always force a computer to go into the BIOS. I might also check that the power to the Hard drive was not accidentaly unplugged as I see the CD-ROM drive was recognized, but I do not see a hard drive which means a couple of things, either the hard drive died or it has no connection to either the power or data cable. Check these and see if your computer will boot.
that beep means POST.. your computer hardware is fine .. please just re install the operating systemm... before that you might want to back up the hard drive data using bartpe or some tools similar to that.. if you dont have that expertise. just re install the operating system .. you should get back to work...
remember beep meaning POST meaning your hardware is fine.. the operating system is just corrupted / broekn
sounds like heating problems. what i'd recommend is to go buy some thermal paste, remove your heatsink/cpu fan. wipe the bottom of the heatsink clean with a cloth, and do the sam with the top of the cpu. now apply the thermal paste (about 3mm cubic or whatever the packaging says) to the centre of the cpu, and secure the heatsink/fan onto the cpu. make sure your heatsink is on your cpu SECURELY. In my experience a pc that boots up, works a while then reboots out of it's own is having heat problems. especially if the pc wont boot/reboots quickly after the initial reboot.
