I recently built a new computer and after several hours spent getting it to actually work and run games, it suddenly turned off and now won't turn back on. The video card said it needed a 400W minimum psu and the one i got is 450W but I'm not completely ruling out psu failure. I tried unplugging the drives, video card, and fans just to see if it would actually turn on, but it still wouldn't. Anyone have any ideas?
 
try another PSU. 450w is mighty weak, you might have toasted it. Other than that there are tons of ways to kill a computer. Check the Ram, the Mobo, the CPU, and the PSU. It will be one of those if it can't post. Most likely is the PSU or mobo if you get nothing, if lights come on the mobo, or the fans run for an instant the PSU is probably NOT the culprit.

More important that the wattage (to an extent, I wouldn't build a pc with less than 550w) is the quality of a PSU, get a decent one, Enermax, Silverstone, Hiper.
 
get a 550 watt or 600 watt psu cause mine said needs 400 or 450 for vid card but with cpu ~usually 20 - 30 watts and all other devices which could be anywhere from 10 watts to 100 watts or more

so get a 600 watt atleast id say because you probably killed the PSU trying to get too much power to something that cant handle it
 
Take out all the cards including video. Unplug all the drives and all the connecitons to the MB besides the speaker, power button and cpu fan power then reseat the memory. Fire it up... see if the cpu fan turns and if it beeps.

If so power it off and start putitng in a few compunents at a time and firing it back up until it stops.

You can also look at the manual for the MB and see how to reset the BIOS. Give that a try if it does not beep too.

if you get a beep and the spu fan spins turn it off and start adding stuff back in. Every few connections fire it up and see if it still works.

If no beep... its the PSU or MB. There is a rare chance that it's a CPU but I've only ever seen one CPU do what you have described.
 
I forgot to add, double check all your connections. I can't tell you how many times I've built a PC only to have it not work because I forgot some silly cable. Check and double check all your power connectors, and do as scragg says. Also you can pick up a power supply tester at frozencpu.com or almost any local PC store (the little guys, not best buy/circut city) pretty cheap, and it sounds to me like that is the culprit. Either way don't put it off, you should be able to RMA anything that's not working.

Can you provide me with complete specs of the computer, models and all...
 
im the one building my own computer, but with the help of my uncle, it could be tough, assembling it is easy but installing programs and stuff could be tough
 
Processor: AMD Athlon 64 X2 Dual-Core Processor 4800+
(65W) - ADO4800DDBOX - Box CPU - Socket AM2

Video Card: EVGA 320-P2-N815-AR GeForce 8800GTS 320MB GDDR3 PCI Express x16 HDCP

Memory: DDR2 2GB PC5300 Dual Corsair

Mother Board: ECS GeForce 6100SM-M Socket AM2

Sound: On board

Hard Drive and CD Drive: I don't know, salvaged from older computers and I'm at work right now so I can't take the case apart and look at them.

Case & PSU: Raidmax Ares Mid Tower Case /w 450W PSU

Fry - where are you located?
 
it says minimum of 400w. i would highly sugggest getting at least a 500w psu for that, most lickely you just fried your psu. You need power to be sending other places than your gpu, such as your cpu and mobo. I think you fried it
 
I'm really hoping that its just a blown psu, but since the LED lights and fans briefly come on when i try to power it up, i'm not so sure it is.
 
i would suggest a pc power and cooling power supply, kinda pricy, but they are the best and most stable out there
 
Yeah that's a bit overkill for an am2 system though. If you stick to Hiper, Enermax, or silverstone you'll be fine, without spending more than the other components. (there is no doubt that PC power makes some of the best, but they also cost way up there. He's only got an ECS mobo, chances are he doesn't want to break the bank.)
 
Sadly when it comes to buying new parts or paying rent, I think I will have to pick paying rent. I guess I'm stuck to using my laptop for a while.
 
ECS is not a brand I'd generally go with for a MB. Also... you may find the onboard sound problematic. You might consider a sound blaster x-fi. If your MB is bad and you have to replace go with a name brand. Asus, Gigabyte, MSI, are all generally good.
