    I reset the bios in the computer, and its still doing it. I still need to get a CD ROM for it. that might be why its doing it. But it should still turn on and show the IBM logo on the screen.

    This computer i bought off ebay. it didnt have any ram, so i have to get some. but i put 148MB of ram in it. i put a brand new 120GB Hard drive in it. im not sure if thats enough ram to run the system or not. it only supports 512MB RAM so i plan on getting that. and its still not working.

OK
You will need to reset the BIOS in this computer.
When you remove the battery from the back of the computer you should see a little yellow disc about the size of a nickel. It is thje BIOS battery and it is in a plastic frame that is held in the computer with 1 screw in the corner. You need to remove the screw and then lift the free side of the battery holder and slide it towards the center of the battery box. This will unplug the wire that runs from the battery into the computer. Leave it out for about 1 minute and then slide it back into position, allowing it to plug the wire back into its socket.
Then put the screw back in and insert the mail battery back into its compartment.
Now when you turn it on it will pop up a message telling you the clock is wrong. reset it to the right time and follow the prompts to reset the BIOS. Make sure that you have the boot sequence set to boot from the CDROM ahead of the Hard drive, or you won't be able to load the OS disc.
Good luck.
I just put a new hard drive in one of these last week and it gave me a bit of a start when it wouldn't start right up.
This fixxed it right up though.

    Try putting the old RAM back in.

    You may have gotten bad RAM.

    Or try it with a single stick of RAM if you got more than one stick.

    I would also think that you should at least get the IBM screen if all your hard ware is good. But bad RAM can shut you down as fast as a bad CPU.

HP TouchSmart 310-1125f display is black


Hearing fans and hard drive spin up doesn't necessarily mean system is working - just without video. If you heard a POST beep or the Windows Startup sound that would be different - and good. Is there any video on the screen at all, even just a blinking cursor in upper left of display? If not, your problem is probably hardware such as ram or motherboard. If this system has a VGA or HDMI output to connect to another monitor or TV would be a good check, but AIO system usually don't have that option. Other than that, and this is a shot in the dark: Ensure the system is off, disconnect the power plug, and hold the power button in for 30 sec for a power reset. Then plug in system and try powering it up again. If no go, you may have a hardware problem and will need a PC Tech. Hopefully it is just loose ram.

My acer aspire starts z5700 starts beeping when i push power button, nothing else happens, the screen is black and computer is working


You have to count the beeps to determine what work. Overall if the system beeps on startup it sounds like the memory (RAM) is not working. My suggesting to either buy new RAM or reseat the existing memory by taking about and put back in.

Gateway desktop powers on, but no display


Hello my friend, try to check your power supply and try to insert correctly your RAM. And for your last option of troubleshooting is to apply a silicon compound to your processor. Then if it does not solve your problem try to reset the motherboard. How to do these follow this steps.

1. Pull out first the CMOS battery.
2. Next pull out the Memory/RAM.
3. Pull out everything that connect to your Hard drive and CD drive.
4. Set the jumper settings of your CMOS to CLRCMOS that is Jumper 2-3.
5. Turn on your system unit and let it for around 15 minutes.
6. After a period of time, put back all what your pull outed.
7. For best diagnostic test, first put the cmos to normal, then put back the memory and test. If it beep once then you successfully reset your motherboard. And if you are successfully reset your motherboard put back all to normal.
That's all.

Hope it would help you.

Good luck.

Pushing the power button, the screen stays black and one beep every 6 seconds, no way to reach to bios etc.....


Had same problem. I unplugged the hard drive from inside the computer and plugged right back in. You are possibly getting a bad connection to your hard drive. If that doesn't work then don't know.

HP Pavillion dv6700 - black screen


Do the following without the battery inserted.

Let the computer sit with no battery for 24 hours. Do not put the battery in at all. Try using your original memory stick ONLY, with no hard drive and see if it will POST. If it does, insert the hard drive and try again. Could be the new memory...

Another thing you can try is reseating the processor. Turn the ZIF screw, take the processor out (WATCH THE PINS!!) and put back in GENTLY. Leave the memory in the computer, hard drive removed, try to power on.

These models have been known for bad motherboards. Contact HP and arrange to send it in. If you do enough digging on HPs website, you'll find the service advisory.
