One night I turned off my computer. The next day it wouldnt turn on. The power light comes on and blinks rapidly, now I cant get it to turn off or on. There is no boot up, no nothing. I real new to messing with computers so Ive been hesitant to open it up. But then I dont know what Im doing anyway. If anyone can help figure out this I would greatly appreciate it

have you tried holding the power button in for about 10-15 seconds? this will usually kill the power to the board. Then power up and see how it goes from there.

Yeah, Ive tried holding in the power button, held it for 2 minutes and the light doesnt go out. There is nothing running on the computer, it just wont turn off and the light blinks very rapidly. It hasnt booted up either. No fans running, no nothing. I turned it on one day and all it did was start blinking.

Have you tried pulling the power cord from the back of the system and plugging it back in? If so does it still do the same thing?

Yeah Ive pulled the plug and even turned off the switch where the power cord goes. Same thing happens, as soon as I plug it back in the light is still rapidly flashing and not doing anything else

If you are plugged into a surge protector or UPS, try plugging it straight into the wall. If killing the power for a few minutes doesn't do the trick, it sounds like a hardware failure. Could be faulty power supply, or mainboard as the first possible culprit. I would suggest getting it looked at by a competent technician.

If it is the ram shouldn't the fan inside be still running?

I think it may be a power supply or the mother board.

I think its the power supply or the mobo thats gone, dont think there would be any issues with the RAM, dead ram would simply bring a blue error screen but other hardware would still function like the fans, drives etc.

Lets just hope it is the PSU not the mobo for ya.

Thats what Im thinking PSU or MOBO lets hope its your PSU for expense sake. try another PSU first in your machine you might just find the solution.if you can remember something suspicious that happend when it was working good/previous night you might just find an a hint to what might have caused it.

You have piggybacked on an old thread. (27 Days Ago)
Unplug any/all CD/DVD, Floppy (if fitted) any/all hard drive and remove your Video card. Plug your monitor directly into the motherboard. Try to see if you get a message on the monitor.
What ever happens, start your own thread and give a lot of details about your PC and OS. How long this has been happening, what you have loaded or updated etc... And explain what you have tried.

Hi highlandshighsc and welcome to Daniweb,
Please read the rules for posting in these forums. No piggybacking, as you have done. No abuse to other posters, as you have done.
And as a matter of interest the odds are about 90% chance of RAM being the problem of no video display to about 10% mobo.
Therefore, start your own thread, don't use your post to be abusive, get your facts straight and supply much more information if you require assistance.

when ever the blinking light comes up, that means the mother board is dead... you can call the company and check if your warrnty is still valid.. if its not i think you need to buy a new motherboard.. but before you do that make sure you have the right rams and video card that can fit in the motherboard.
