I have an Accer Aspire AST690-UP925A, problem is when i turn it on lights flash like it is booting up but not sure if it is because nothing shows on the monitor except when i turn the moniter on it shows ''no signal'' then turns off. Anyone know what causes this? Occasionally there is a beep along with it but not always. The monitor works just fine on other computers, but when i put other monitors on this comp. the same thing happens. Any ideas would be appreciated. Thanx

This could be from the setup procedure in the Bios.
When you start the computer, hit DEL and see if you can open the Setup section. Look around for BOOT START whereby a command may be RUN TEST when Starting, or something like that reference. Just select Turn OFF or Stop, whatever command is showing. Go to F10 or save, and restart the computer. If that did not stop the problem, you may have to clear the BIOs completely and reset the data from scratch. Some computer BIOs allow for a reset to DEFAULT.
how is the monitor connected to the computer? what connection type is the monitor is it VGA or HDMI . What format is the computer video output is it VGA or HDMI. Also you may have two video outputs on the computer. Sometimes the motherboard vga output is disabled so that a much better video plug in card can be used which has its own video output port.
Something is causing Windows not to start up. The computer is restarting, and the loss of the signal to the monitor is why the monitor shows you that "no signal" message. You can try selecting the option to start using the last known good configuration and see if Windows starts up that way.
This problem might be due to either hardware or software. I've seen bad memory and bad system boards both cause this, as well as corrupted Windows installations (often the result of a virus or other malware infection). If you don't have any data you care about on the computer, you can try restoring the computer or reinstalling WIndows. This will quickly tell you if it's the hardware.
check for the RAM....it might be defective...make sure the RAM is defective by checking it with another RAM...if it shows display means your RAM is only defective and needs to be replaced.....
is this cleared your problem?
nothing, the computer just restart itself then at first nothing show up

333 to 266 and it boot just up to the boot from cd press any key part
and then it hangs it did'nt boot the window xp
Jordman85, Make sure that you are connecting to the video output on your Compaq that is configured (such as a PCI video card versus the integrated Graphics on your MoBo) and when reconnecting monitors, make sure the machine is powered down before connecting or disconnecting. Since you say that "the only thing that show up is the arrow button", I assume you are referring to your cursor, and if that is correct? You're PC would be attempting to boot to windows and there may be a hardware conflict that may be stalling it. There could also be corruption in the windows installation. But the monitor should be simple "Plug and Play". More details about your Graphics Card and any recent hardware software changes/occurrences that have taken place would help. Good luck.
