Hi,
This is my desktop pc configuration:
Windows Vista Home Premium x64 (in past XP SP2),
cpu: Intel Core2Duo [email protected], ram: 4gb ddr2, video: nVidia 7600GT
(256mb/128) ddr3, motherboard: asus p5b.
Ok, what is my problem:
Sometimes when i turn on my computer, i don't hear the "beep" sound, and on
my monitor i receive this message: No signal input (monitor default message,
not a sistem message). I need to press the restart button to have signal
again...
What can be the problem?
I got this problem when i was having XP SP2, now i have Vista, but not the
OS is the cause...
Thank You.
 
First thing I would be checking is the cable between the monitor and the
tower.
Check both ends(monitor end as well!) for tightness and good fitting.

I don't think it is Graphics as too intermittent; it is normally over and out!

It may very well be the monitor/monitor cable as Mick has suggested but to
me the fact that you don't get a BIOS beep and that restarting using the
power button will sometimes work indicates failing hardware on the
computer. The first thing I would look at is the power supply since the
symptoms you describe are often caused by that.

Standard disclaimer: I can't see and test your computer myself, so these are
just suggestions based on many years of being a professional computer tech;
suggestions based on what you've written. You should not take my
suggestions as a definitive diagnosis. Testing hardware failures often
involves swapping out suspected parts with known-good parts. If you can't
do the testing yourself and/or are uncomfortable opening your computer,
take the machine to a professional computer repair shop (not your local
equivalent of BigComputerStore/GeekSquad). If possible, have all your data
backed up before you take the machine into a shop.
