3 long beeps normally indicate defective memory or loose memory on DIMM so take out and insert it again or you need to replace with new memory module. Where as fast beeping indicates Graphics error and need to change the graphic card

If this dont fix please tell me
Best Luck!

The nuimber of beeps and duration is a code as to what is wrong. Usually beeps inidicate a hardware malfunction like bad or mismatched memory, or CPU or something cam loose inside like a IDE cable, take not on how many beeps and the sequence, and please post back.

Hope this helps.

I cant start my laptop . when i press start i gives beep sound twice and blanck screen


Sub out the ram one at a time and power up each time, if you are lucky! the machine will start up, if not! remove the main battery and try again. If no change! the motherboard is the problem and you will need somebody to take it to the next level and find out the cause.

When I start up my Fujitsu Amilo Si1520, the fan starts working and nothing else happens -- screen remains blank.


Do you hear any kind of beep?
If yes, there is something wrong with your graphic adapter. If there is no beep, your MB is most probably dead

Hp computer beeps and blank screen what cud be the


Check to make sure the new memory and processor is seated in the slot correctly. If either is not inserted fully it will cause the PC to beep and blank screen as your is doing. If that doesn't fix it your memory could be the wrong type or to large for the PC to recognize. JQ

Blank screen


This could be due to many issues. The most likely in my mind are:

1. A dead hard drive, but then at least the BIOS should come up
2. A shorted out or disconnected video connection (it connects at the hinge where the laptop screen folds down)
3. A plugged in USB device that the computer is trying to boot from

About #3, seriously, I've seen it happen. No BIOS, no Windows screen. Just a blank screen and a beep until you remove the USB device.

BLANK SCREEN-ACER ASPIRE 3661


You can check the little indicator light on the notebook.

If the hard drive was dead, that wouldn't cause the display to go blank.
If your problem was with your hard drive, you would still get the BIOS screen and then a message about being unable to load an operating system. So, I doubt if that is the problem.

My guess is that you have a relatively serious motherboard, video card, memory, or CPU problem.

When you turn it on, does it beep ? If so, how many times ? You can translate these beep codes at: http://networking.ringofsaturn.com/PC/beep.php __________________

Blank screen after xp welcome screen no power to keyboard


Ok, with your current set up, what beeps are you getting? Also, while you have a blank desktop, hit CTRL+ALT+DELETE and you'll have Task Manager come up, click File and then New Task and type in "explorer" without quotes and hit enter. That should restore your desktop. Let me know how it goes.
