Re: My DC5100 Gives beep sound

This is almost definitely a RAM issue and usually its the ADD ON memory. The way to find out is to test each one separately on the same slot.

My hp-compaq dx2300 microtower restarts automatically when working. It is installed on win xp sp3. Please let anyone help if solution is known.

Hi names Rui, i question for you does your PC give a beeping sound when you turn it on? if does can you tell me how many beeps it gives?

if it give a designated number of beeps this might be the problem i will give you a chart so you can differentiate the warning beeps you hear.

warning beeps:

1 Short Beep DRAM refresh failure
2 Short Beep Parity circuit failure
3 Short Beep Base 64k RAM failure
4 Short Beep System time failure
5 Short Beep Process failure
6 Short Beep keyboard control gate A20 failure
7 Short Beep Virtual mode exeption failure
8 Short Beep Display memory read/write test failure
9 Short Beep ROM BIOS checksum failure
10 Short Beep CMOS shutdown read/write error
11 Short Beep Cache memory error
1 long, 3 short Beep Conventional/Extended memory failure
1 long, 8 short beep Display/Retrace test failed

hope this will determine the problem if none of this warning beep is heard try reseting the power botton in you PC cause sometimes the power botton will loosen cause of continuous use of the botton.

hope this will help you.

Computer won't come on-it gives one short beep. it flashes some computer language - briefly - three different times and then screen goes black but does not shut off. how do I fix this?

One "beep" is good -- multiple beeps mean something is wrong.

Restart your computer, and be ready to press the PAUSE button on your keyboard, to "freeze" that text on the screen, so that you can read it.

My computer does not boots and while booting i can hear three beeps and than it gives me a message to check my pc and signal cable

sounds like the video card to me both by the three beeps and the message, try taking the video card out and putting it back in, or pushing it all the way in if it got knocked out. it could also be RAM, if those are loosened at all they can all sorts of strange problems and even make the wrong error messages occur, try reinstalling both.

I had 3 beeps, pause, 3beeps, pause and so on.

Defective SMD transistor near the ATX power connector. Original is a 2SB1202 (marking B1202).
I bought a 2SB1203 which is stronger and soldered it in. The K7S41GX board runs as fresh as from the dealer.

HP desktop wont start up

Hi, depends on the beep sequence, it could either ba a bad memory or a bad video card. By being bad does not necessarily mean defective but could possibly be just loose. Try to open the casing/cover and reseat/push back into place the video card (if it is not built-in) and/or the memory. It is possible that they were jarred loose while in transit. Pls make sure the unit is unplugged before doing this. BTW, being new, you might void your warranty if you open the casing, pls check your warranty card. Hope this works out for you. Please let me know how things turn up. Regards
