Question about Acer Computers & Internet
I check the power supply and the VGA cable...when i power on the cpu fan is ok but no display
Check the led light indicator of your monitor. Is it green or blue? Or is it yellow or orange? If it's green or blue, then there's no problem with your monitor. If it's yellow or orange, you may have a defective or dirty graphics card or memory.
Open your system unit chassis, remove the video card (if you have) and the memory or RAM from their slots. Clean the gold contacts or pins with a rubber pencil eraser, then wipe it with a lint-free cloth to remove the debris. Then put it back again to their slots. Test.
There's a lot of instructional videos on youtube on how to remove these parts properly, so better watch them first if it's your first time.
Hope this may help you, please rate my answer. Thank you for using fixya.

SOURCE: gx260 pc wont start
Either the motherboard or power supply are bad. I've had both be the cause of the problem. Check the motherboard for bulging and discolored capacitors. The same can be true of the power supply.
To the guy above who said his were out of warranty. If the motherboard is the cause of the problem, Dell will replace it until near the end of January. Just call them up and try to convince them. We are an educational customer, but everyone should be able to get it. It's a known defect.

SOURCE: No display and wont boot
A Blinking Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. This can be caused by a defective power supply or a defective motherboard. Power supply is easier and cheaper to replace.
