Speakers are not working. They are on but still no sound
Do you have a pair of head phones that you can plug in to the PC and see if you can get any sound?
Have you checked your VOLUME control on your PC to make sure it's not set to MUTE? (you can either find it down in the right corner of your screen next to the clock and other icons - it looks like a speaker sort of or you can find it inside your CONTROL PANEL under sound).
Please post here to let me know how it goes.

the LED indication is a Memory failure. Make sure when inserting RAM that the power is unplugged and you press and hold the power button till all power is discharged from the motherboard. WHen inserting RAM, make sure levers are int he full back position and you press down firmly with both thumbs till the module snaps in place and the levers snap up in the locked position on their own (DO not pull up the levers)
If there is no change trying RAM modules in slots individually, then either all RAM modules are damaged, or the slot is bad, in which case a motherboard is required
Vista is available in 32 and 64 bit os.
if your system ran xp which was most likely 32 bit. And you have installed a 64 bit version os.
this will be your problem, also Vista requires more system RAM/Memory to run it.
If you get 1 beep at startup, it states the system is ok.
Alternatives are device drivers incompatability.
Check M$ website, regarding vistas minimum system requirements.
your speaker connections are plugged in incorrectly or the speakers are not plugged in and powered on. check the back of the computer where your speakers are plugged in and make sure you speakers are plugged into the right colors
Its possible that the cable from the laptop to the monitor is damaged. I would #1 make sure that the connection into the pc and into the monitor are both snug, if they are just slightly off it will keep the monitor from powering on. If they are snug, try another cable (if you have one) or hook the monitor to another pc (possibly your laptop, if it has a video out). Let me know if that solves the problem.
When you power on the computer,try pressing F8 key until you get a prompt screen,you will find many options,there you click on LAST KNOWN GOOD CONFIGURATIONS.it will work. If this trick does not work try same procedure given above and this time you press SAFE MODE.The computer will start in safe mode.There,you can restore your your computer to a date in which it was working properly.it will work.
