We just had a power outage and when the power was restored my computer will not turn on. I press the on button and nothing happens. There is a green light in the back that is blinking. Is there a reset button? Please help.

First off: Protection is important and the ONLY way to go is with a UPS (Battery backup protector). These devices allow the computer to SLOWLEY close down and protect the motherboard and hard drives. Simple bar protectors are of little to no use whatsoever. As for the Start UP; the Boot Sector on the Hard Drive has been compromised. If you attempted to start with the F8 key when you started up the computer and failed to Boot in the Safe Mode, you definitely lost the operating system.
You can try to do a Restore, but that may not be effective.
When a Computer starts, there is usually a Beep (called a Post) and one Beep indicates the motherboard is active. Several beeps indicate a mal-function of the motherboard and it was damaged. In some cases, the Memory (RAM) can be damaged from electrical surge, and thus the computer will not start and the monitor will not be active. Do not touch the internal leads as they are not the problem. In closing, a CPU is very sensitive to power surge and the CPU in some cases can be defective. All in all, with so may options or repair issues; only a professional has the equipment to search for the solution. Good luck: DaytonComputerDoctor@hotmail.com
Depending on how long the power was off, your desktop power supply circuit capacitors may have fully discharged during the power outage. This will effect how fast your computer will turn on when you press the power button. Turning off the power by pulling the cord, or a power outage while the computer was on will usually result in a message that Windows was not shut down down properly when you try to restart it. Also make sure your computer isn't plugged into a 'switched' receptacle that's wired to turn on a table lamp etc from a wall switch. It's usually the bottom half of the receptacle that's switched while the top plug is always 'hot' or powered and unswitched in a wall switch controlled recepacle situatation.
Sounds like it could be the power supply was damaged from the power outage. If you have another PC you could pull the ATX power supply out and install it in the gateway and see if it boots up. Power supplies are fairly inexpensive so look for an aftermarket one...buying a replacement from Gateway will cost alot more. If the power supply turns out to be good then remove one device at a time the try to boot up. Sometimes a bad cd-rom drive or harddrive can cause a problem. My best guess it is the power supply.
while rebooting u press the F5 key for a while, it will redirect u to a boot menu,in this boot menu u have some special options to boot like boot in safe mode,safe mode with networking ,debugging mode,last known good configuration boot,start normally,etc u first boot in safe mode and try to deactivate rebooting in ur own technicand u have more options try all of them it will be ok in 2 or 3 options
the easiest option will be to do a system restore to before the outage; Start/All programmes>accessories>System Tools>System Restore.
Then choose restore my computer to previous settings, then choose a date that is not greyed out.
Hope this sorts it
