Hi sir,

Hope this will give you ease of mind and or hints. The No Signal error screen message is normal it depends how much delay it responds to (design or default time delay) the video card down to CPU and control units. The blank screen can be resolved by turning off the screen saver(s) you have and even to BIOS mainboard setting; disable the "turn off monitor after how many seconds" or related menu, etc.. Hope you can manage to enter BIOS maiboard setup.

Best regards,
Rosener Guyano

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. - rules
Test all power and data leads that attach to your hard drive IDE,SATA
the leads from your (motherboard to your hard drive) make sure they have secure dust free connections and are not faulty
if its a 40 pin flat ribbon type it will be the first to fail
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty
even something as small as a faulty electrical fan and its lead can cause you problems
computers need all power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error
Check your RAM.
The RAM is located in the middle of the motherboard.
There are tabs that you can push to release the RAM.
Remove it and put it back in place until the tabs pop out.
Loose RAM can cause your computer not to start properly where you want to see a video signal.
Make sure your graphics card is securely seated with no dust built up or in the socket
if you remove your graphics check the socket to make sure its dust free
Restart your computer then reinstall it this should activate found new hardware wizard
Check the vga lead for secure dust free connection or try another vga lead.

My Hp slimline desktop is getting a 'no signal'

more than likely it is set to to the wrong frequency. try and start the pc in safe mode and adjust the frequency to 60 hrtz. that should take care of it.

Why does my Compaq Presario sr2020nx keep beeping at me?

The beep and looping the start caused by the ram memory ..Open it up and remove he ram modules without direct handle ..but from teh ends..(due to the static elec.) and insert them back one at the time and try to boot..if it boots up with one of them it means that is working ..try the other and if it fails this one is faulty and need replace or leave it work with the one it has..(issue is if you have minimal memory for windows vista or seven and after that will not be able to work and need windows xp ) ..
If it just beeps long and there is no looping is the video card to blame ..remove it and use the on board one if you have ..or ..replace the video card ..(in this case it will also display the no signal on screen )

I have an X-box360 and my router is not working. How can i fix it in my own home.

The first thing you should try is the simplest: turn your router off, and let it rest for a moment. After turning it back on and allowing it to completely start back up, restart your computer, X-Box, and all other things that it might not be working on, to be sure that they are picking up it's new signal.
If nothing has changed, make sure that all of the proper wires are plugged in for your router.
If none of these basic steps are working - what error messages is it giving you? Is your X-Box360 simply not picking up the wireless signal? Does your computer's wireless connection still run smoothly?

Static noise so cannot hear anything

Do you have WI Fi nearby as it distorts signal sometimes. Changes wi fi band width and it should clear problem.
