Hi I have an Acer Aspire M3300 -E1222 desktop computer Amd athlon II X4 620 quad core processor 4gb DDR3 with an Acer 21″ flat screen monitor. My kids left the computer on last night and we had a power outage. Now the desktop seems to boot I hear the fan and the power button lights up but the monitor show a “no signal” messge then goes to sleep mode. Help!!

Something on the the computer could have been damaged even if the computer wasn’t running at the time, if it was plugged into AC.
The most frequent thing I’ve seen is just the power supply was damaged.
A damaged power supply often produces similar symptoms to a failing power supply
Failing power supplies are common and can cause your symptoms.
They often partially work, fans and hard drives may spin, leds may come on, yet you may get no video and the mboard will not boot all the way.
If you’re fortunate, replacing the power supply will get your system working again.
However, sometimes the mboard has been damaged, either by the power supply failing, or by the the power failure event’s power spikes and/or surges.
If you can borrow a power supply from another working system, try connecting that to your system.
If your power supply when connected to another working system doesn’t result in you being able to boot that computer normally, the power supply is definitely damaged.
NOTE that if the brand of the power supply is BESTEC, that brand of PS is known to be MUCH more likely to damage the mboard while failing.

If trying another power supply results in your system working…..
Your mboard’s AMD 780G main chipset supports Hybrid CrossfireX Hybrid video – both the onboard video adapter and the video on a video card in a PCI-E X16 slot working at the same time, but that feature is ONLY supported if the video chipset on the card is ATI and one of a short list of video chipsets.
If you install a video card in the PCI-E X16 slot,
– your system came with either a 250 or 300 watt PS. There are very few video chipsets on PCI-E X16 video cards that will work fine on a system with such a meagre power supply capacity .
Your replacement power supply should probably have a higher wattage capacity.
Your power supply must have at least the minimum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video – video built into the mboard – IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker’s web site and look up the specs for the model – often under system requirements – the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don’t find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings – in that case, add those ratings to determine the total +12v current capacity.
– if a PCI-E X16 video card has ANY NVidia video chipset on it, or an ATI video chipset that is NOT one of the few supported by the Hybrid CrossfireX requirements, default bios settings MAY result in you getting NO VIDEO video from the PCI-E X16 video card.
In that case, you need to connect your computer to the onboard video port, which is STILL producing video, and change at least one if not two settings in the bios Setup from their defaults in order to get video from the card in the PCI-E X16 slot. If you need more info about that, I can provide more details.
