Question about Computers & Internet
I have a 304w hp i turn it on and nothing on montior black screen , i can see and feel cpu fans on and feel the hard drive its running , but nothing the led light on back stays green and no beeps,
First try removing the hard drive,and turn on the power. If the screen is till blank then either the memory sticks are no good,or the power supply to the screen could be tripping. But if the screen is not blank then your "MBR" (media boot record) is missing or off track.

Try pulling the plug from the back of the machine or the wall and then plug it back in and see if it will come up. It may be stuck in what I call a voltage loop. You can also try re-seating the card and memory and making sure the cable from the monitor is connected firmly.
If it doesn't do anything it is possible that either the video card is going bad, the power supply is failing, memory is bad or possibly the motherboard is shot.
Let me know if I can help any further.

Tips for a great answer:
Test your PSU or replace it if your power supply units fan is not working your PSU is faulty
One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive
Test all leads that attach to your hard drive including electrical extensions,IDE,SATA
the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error
hope this helps
