Question about Computers & Internet

1 Answer

I have an Acer SA90. When I start up the monitor and keyboard stays off. The base unit turns on, but the red light at the front stay solid instead of blinking. i have checked all connectionos and it is definatley not the monitor as that says no singal being received on it. Also the base unit won't let me do a cold shutdown, no matter how long i hold the power button in for. Could the problem be my graphics card?

Could be a whole lot of things.
Any beeps from the mobo?
Reseat the RAM.
Are your drives spinning up (hard disk drives)
How old is your SSD (if that is what you have)
Have you tried a different monitor?
What GPU do you have?

From what you have described, it really does sound like the motherboard (mobo) has died, without more information it is hard to tell though.

SOURCE: PC is dead

I assume you installed the new graphics card already. Did you check if your power supply could handle the increased power? If your power supply is rated at 350W or less, I'd upgrade to at least 400W.

Also, ensure that the graphics card, if it has a power connector, is connected properly to the power supply, and that in the process of installing it, you didn't accidentally remove any of the power connections to your motherboard.

The Green LED lets you know that it is receiving power from the wall, and that the problem lies in the computer somewhere.

SOURCE: acer aspire T120c wont start red

If you turn on the computer and it will beep once and the red light blinks means the computer is starting will.. but if the computer beep once and the red light blinks once means there are something missing or something bothering the computer.. try this Check the connection cable of your computer, the power source, the hardware interface, and if you installed a new hardware, try taking that hardware out and turn on again the computer. if the problem still exist try to disassemble and assemble the hardware of the computer. You must have someone with you know how to assemble and disassemble the computer hardware for safety method TY.

HOPE I CAN HELP

SOURCE: Tv will not turn on

all you have to do is replace the 25 volt 1000 uf capacitor on the inverter board. there are 2 of them. typically, only 1 goes bad. I had the same problem, replaced the ca, and now it works great.

SOURCE: projector turns on the power light flashing and lamp light solid

Here's the fix: Take off the top cover of the projector. Unplug the wire leading from the two fans in the back of the unit to one of the circuit boards in front of you. Just trace one wire from fan to board. Unplug at board. Turn unit on and it will again turn on, show HP splash screen and then shut down, like it should, because the fans are now disabled. After it completly shuts down, plug the fan wire back into the board. Turn the unit back on and, presto, its working again. It will not turn off.

Try it!

Hello, My Graco monitor shows a red light instead of the normal green light and it says "discard jetez". It also beeps. What could be wrong?


I just fixed my unit that had this same problem. You have to re-pair the two units... Turn the parent unit off. Hold the "volume down" button while you turn the parent unit back on. The unit should beep and flash all volume lights. Release the volume button and the press again for ~2 seconds. The volume lights will light up and stay on. Next, turn the nursery unit off and then back on. This should re-pair the two. I hope it fixes your problem!

Green light flashing, but monitor won't come on


Sounds like signal issue, some older monitor lights do not turn orange when no signal is present from the computer. They simply blink instead of staying solid.

- I would test to see if monitor works on another computer with a known working monitor. If the monitor works then you know you have a video output issue.

If the monitor does not, you have a dead monitor.

The power button may not work, that is most common in laptops, or you have a short.

Monitor Not Showing A Picture. Light flashes Yellow and Green.


use the onboard graphics instead of a seperate graphics card (if installed) to test the screen.if it still doesn't work then unplug your monitor from the mains supply and plug in again to reset it. i doubt it's your monitor that is the problem though. but look on the back of your pc for another connection for your screen. the onboard graphics connection is normally vertical near your ethernet port and mouse and keyboard inputs.

please rate me and give me a fixya! if it helped.

My first guess would be a video card problem. I don't understand the keyboard/mouse issue, Is it because you can't see the screen? Or do they not light up?
