Memory problem my system can't start and it does not display anything but it produces three beeps what can i do

This usually means there is a memory problem or no memory at all.

Well, if it was faulty it would detect it on POST (power-on self-test)
and beep. So, you could start by making sure that your display monitor is working ok by plugging another system or laptop into it, or plugging a known good monitor into your barebones system.
It's only a start, I know, but you have to know that the display works and not just assume it does.

This is a list of ThinkPad Beep codes.
It appears you have a memory or motherboard problem, most likely a RAM problem. Try reseating the RAM modules, if this doesn't work, then remove the RAM and take them to your friendly computer repair shop to get them to test the RAM modules for you. If the RAM is faulty them replace.

The long beep during post means there is a conflict in the start up procedure in the Bios. This can be anything from bad ram to hardware failure. If it starts up and the time is wrong the beep could be your internal bios battery is dead.(just a small watch battery )

The beep codes below may help you identify the possible computer problems. However,
they are only for reference purposes. The situations might differ from case to case.
gAMI BIOS Beep Codes
*Computer gives 1 short beep when system boots successfully.
*Except for beep code 8, these codes are always fatal.
1 beep Refresh failure
2 beeps Parity error
3 beeps Base 64K memory failure
4 beeps Timer not operational
5 beeps Processor error
6 beeps 8042 - gate A20 failure
7 beeps Processor exception interrupt error
8 beeps Display memory read/write failure
9 beeps ROM checksum error
10 beeps CMOS shutdown register read/write error
11 beeps Cache memory bad
g AWARD BIOS Beep Codes
1 short: System boots successfully
2 short: CMOS setting error
1 long 1 short: DRAM or M/B error
1 long 2 short: Monitor or display card error
1 long 3 short: Keyboard error
1 long 9 short: BIOS ROM error
Continuous long beeps: DRAM error
Continuous short beeps: Power error

possible memory (RAM) problem.

try removing all memory(RAM). reconnect just 1 RAM. if it doesnt work reconnect another RAM.

ok...and these beeps..do they happen before screen shows anything?

system is on but no display. yes i did heard sound 3 beep sound from the motherboards.

1) You need to change your memory, the may be bad, and it will not display anything on your screen.
2) Make sure that your processor fan is well connected

Starting the PC without memory will result in a ?beep code? error, which is the beeping you are hearing. Replacing the memory should make the beeping go away. As far as accessing your BIOS if you PC won?t display anything they accessing your system BIOS won?t accomplish anything. -When you start your PC with the memory installed do you see anything displayed on the screen? -Was the PC operating correctly before your reinstall? -Why did you void the CMOS? -Why did you remove the PC memory?
