Hearing fans and hard drive spin up doesn't necessarily mean system is working - just without video. If you heard a POST beep or the Windows Startup sound that would be different - and good. Is there any video on the screen at all, even just a blinking cursor in upper left of display? If not, your problem is probably hardware such as ram or motherboard. If this system has a VGA or HDMI output to connect to another monitor or TV would be a good check, but AIO system usually don't have that option. Other than that, and this is a shot in the dark: Ensure the system is off, disconnect the power plug, and hold the power button in for 30 sec for a power reset. Then plug in system and try powering it up again. If no go, you may have a hardware problem and will need a PC Tech. Hopefully it is just loose ram.
blubaju, probably cold-cathode-fluorescent-lamp backlight failure! if unit dosen't have electro-luminescent style backlighting. All LCD panels require WHITE light to see what is on the screen!!! Is same common problem that computer (pc) lcd monitors suffer from!!! I suspect that if your unit has CCFL's, that the SMPS power supply or CCFlamp INVERTER circuit has a problem common to ALL LCD monitors. I should think that any BIG TIME tv/monitor repair shop could examine the printed circuit boards and effect a repair for you! Just mention that you think it suffers from the BLACK SCREEN of DEATH syndrome!!! Also mention that to RAYMARINE!!! when you call them and **** them out!! 12fixlouie .5hr nrth/wst of Windy City Rate this on fixya if this msg helpful??
The new RAM memory is the culprit. Remove the memory and insert and test one at a time. Either they are different from one another or not the right memory for your system. If neither modules work, put back your old memory and see if the problem disappears.
usually there are 2 problems:
1. a vga card overheat when running 3 games the vga card heats up. try using an case fan or adn a vga fan.
2. the game uses a high refresh rate in this case tri to set a default refresh rate from the vga driver.
hope this helps
When you switch on the computer and monitor does the monitor power light illuminated? If not check the power cable, if the power light is on try connecting it to another computer, if it works on another computer then the fault is in your computer or a faulty video cable (try another video cable). If the monitor does not work then it is faulty, if it is OK then your computy is faulty.
If the fault is in your computer, you didn't exactly pinpoint the nature of your fault. Does the power light on your computer illuminated when you power up? Does your computer actually boot up, does it give and beep code (count the number of beeps - 7 beeps usually means video problems, depends upon the type of BIOS)? When your computer first boots up and you see POST information on the screen then nothing, it is most likely :- 1. The refresh rate of the video card has been set too high beyond the monitor's specification. 2. Video card configured with incompatible monitor.
If you computer fires up and the monitor is OK the you have a faulty graphics card, you need to replace it.
