Lights 2 and 7 and constant beeping

Can't say exactly what it means technically speaking, but my experience with such a problem is that the drive is 'dead'. Of course trying it on another computer would be constructive.

1) adjust the REED swithc , see the diagram clean , and tight the wires connector very well.

2)Try to RUN the software calibration for diagnose, and troubleshooting.

God bless you

OK. First, I'm assuming that you have a Dell Vostro 200 as per the topic title. That said, you machine has a maximum memory capacity of 4GB. So, if you added the 2 - 2GB DIMMS in slots 3 and 4, leaving your original memory in the machine, you will have problems. You must be using DDR2 667 or 800 MHz RAM and the two DIMMS must be in slots DIMM1 and DIMM2 ( closest to the processor). No more than that can be installed.

Constant beeping when you turn a computer on is an indication that you have a RAM memory error. To confirm this, open the tower (after unplugging the unit and pressing and holding the power button in for 10 seconds to confirm there's no charge left). Locate the sticks of RAM memory and remove 1. Then plug the unit back in and reboot. In most cases, the beeping will go away and the machine will boot up. This doesn't usually mean you have a bad RAM memory module, just a bad "bank" on the motherboard. If you like the machine, and removing the RAM works for you, you can either run minus the stick of RAM (the machine will be slower) or do a motherboard upgrade. You can usually get a good motherboard + CPU upgrade in the $90 range. Choose a motherboard that will accommodate the existing RAM memory to keep the project cost effective.

Ive been told that this is a faulty cold water valve. Just got of the phone with F & P as my machine is doing the same. Bout $60 to replace

That's usually a bad ram stick. Shut down the pc & remove one stick at a time starting with the one furthest from the cpu & work your way down to the first one. When it boots without the constant "beep", you found the bad one! You can also check www.msi.com & look in the support area for a solution if mine is wrong.(I'm never wrong though,lol)

a constant beep indicates either a power supply, motherboard or keyboard problem.

If you know what you are doing then open up the case (turning off the power first of course and earth yourself by touching the case before anything inside it) and make sure all the connecters are seated properly and try a different keyboard if you have one.

i have the problem when i turn power on 2 green wash cycle lights plus the red lid lock stay on with constant beeping every second then when i push the start button the 2 green lights go out and the red lid lock light stays on but no beeps please help

pls try to use another compatible memory stick.

then confirm the status of your micro processor

Question- the beeping, is it short (1 second beeps) or long (2 or more seconds) and how many before it stops? or doesn't it? does it have any rhythm? The beeps correlate to some hardware problem, if you want to check the beeps yourself, just google "Bios beeps" and it will bring up a table of what the beeps mean.
