Recently my computer has been shutting down without warning, I ran a memtest to see if it was my RAM and i noticed that one of the sticks was bad so I took them out and started running on 4 gigs. Now a day later my computer shuts down again without warning and when I hit the power button it lights up for a second then shuts off. I then unplug the power cord and move it to another outlet and I keep trying. I then turn off my surge protector and turn it back on and it power ups without a hitch. I'm trying to figure out if this issue is computer related or I'm getting bad power into my outlets? I don't think my proccessor is overheating but I'm not sure of the best method of monitoring that is. I also don't know if its a conciendence that some of my ram has gone bad at the same time this is happening as well. Do you think I might of gotten a surge that my surge protector didn't protect me from? I'm not sure if I should replace the power supply or what at the moment. Also I don't have a UPS so I'm wondering if maybe I need to get one

The power supply is a Corsair 750TX

update: it just powered off again at the windows login screen. Inside the computer is warm, but its not to hot to touch or anything.
 
I ran prime95 for 30 mins while monitoring the temps with speedfan and the core1 and core 2 temps never went over 40c. So I don't think my CPU is overheating, the only thing left to check would be my Video card, does anyone know of any programs that will really bog down the video card, but runs in a window so I can watch speedfan?
 
well i loaded up WoW and stood in Dalaran which has the most players of anywhere in the game and my GPU never went above 45c so I don't think its a heat related issue...so that only leaves either the power coming from the wall or my power supply.
 
The power button on my case will get stuck pushed in and I have to use a screwdriver to get it to pop out, so I was wondering if maybe that was shorting out and sending a shutdown signal to the motherboard so i disconnected the power button from my motherboard, and used the handy onboard power button and so far it has not shut off, but I don't know if that really is the problem because it hadn't shutdown since I took out the bad ram on sunday, but shutdown today twice in rapid succession. Can anyone recommend a good UPS that might help regulate the power coming from my wall socket? I'm not sure if that's the reason but I have been meaning to get a UPS for some time now.
 
You can use the reset button as a power button, just move the connector to the power leads.
 
Also, if you have a circuit city near you, check out their sale. The one near me has 40-50% off of APC UPS units. I picked up a 750VA for around $50 (or was it $60?) last weekend.

What case do you have? If its a popular case, you can probably get the power switch RMA'd.
