Computer won't boot up....

[robqx4]

I heard my computer beep this morning and when I went to check on it it was stuck in reboot so I shut it off. A few minutes later I tried to restart it to no avail.
It starts up with the fan and lights going but is missing the regular beeps I normally hear and I get nothing on my screen. It just seems to be stuck or something.

Please Help!! I'm very novice when it comes to hardware.

Okay, so you don't get the first beep, indicating the post completed?

The post beep indicates all hardware is good. If it doesn't beep, then you have a problem.

First, open the case, make sure the CPU fan is spinning.
Second, remove and reseat all expansion cards.
Third, reconnect all cables.

If that doesn't resolve it, you need to start swapping parts as a test. Remove everything but the video, motherboard, cpu, ram and power supply (this means disconnect your video, cdrom, floppy, network card, etc...). Try again. If you get something now, readd your components, starting with the video, one at a time.

P.S. Please always take the time to backup any and all data before performing any actions suggested for ANY problem, regardless of how minor a change it might seem. Also test the backup to make sure it is intact.

I take no credit for this...this is the first hit on a Google search.

No beep, and no post means the CPU, and the board are not transferring any signal codes. in this case follow these steps:
1.Please be sure CPU is seated properly.

2.Please be sure JP5 is set on Pins 1-2. System will not work if JP5 is set on 2-3.

3. Check jumper setting for CPU (if applicable) , try lower CPU frequency if possible(e.g. set a 500MHz CPU to 450MHz to see the results).

4.Try remove all unrelated hardware from the computer such as sound card, modem, NIC, SCSI, and Ram modules, etc...., ONLY leave CPU, CPU FAN (Be sure CPU fan is connected to CPU Fan #1 if applicable), Chassis speaker, and the ATX power plug and the power on/off switch(PWRBT), make sure you do not have any memory installed.

For P4 users in addition to the mentioned diagnostics make sure that your power supply is a P4 Certified, which contains both the main(20 Pin), and the 12V(4 Pin) connectors. also please make sure that both connectors are properly connected and are generating the necessary power to the board.


5. Turn system on. Check for beeps or any voices(on some boards only). If it beeps then the CPU and the motherboard is communicating, Click Here to look up the beeps code in the Assistance Guides to determine the problem. If no beep or voice then CPU may be defective provided that the speaker is good. Try next step.

6.Try clear the CMOS via JP5 (make sure power is removed from the board) , move jumper cap from pins 1-2 to pins 2-3 and let it sit there for about 10 seconds, after that move the cap back to it's original place(pins 1-2). then try turning the system ON again and check for beep.

7.Pull the board out from the case and isolate it from the case. and try steps1~6 again. If still no beeps then check make sure the power is coming on and CPU fan is turning. If fans are not turning it means power switch or the power supply could be faulty. Try replace power supply first.

8. if the above mentioned steps fail, please try a different processor. it is very much possible that your processor, is defective, or damaged during installation.

robqx4 - this question should be posted in a hardware forum - best one is forum602.

Have you any relevant information prior to hearing the beeps? (any problems you were having, any changes you've made etc).

thecareaga has given you a reasonable list - it sounds like something has died (power supply, motherboard, cpu favourites).
