Solved Computer suddenly turned off and wont start.

Specs: Windows 7, 2.1Ghz
Okay, so I was playing video games when my computer suddenly turned off. I was playing for about 2 hours now. When I tried to turn it on again it wont turn on. No signs of it having power. So I decided to check it inside if I burned something up while playing since it was pretty hot, nothing seems to be burned. I check the power cable, the one connected to the psu and it was kind of burned so I replaced it with a new one. Still no luck. I tried pressing the power button for 30 seconds and turned it on again, still no luck. So I was thinking it was my power supply since the power supply I was using is a stock psu that came with the case (its a fortress case and the psu is 700w model gpl 3cmsf)... I was thinking of replacing the psu with a new one... Any recommendations for a good but cheap psu?

Gigabyte A75M-DS2 (rev 2.0)
AMD A6 3500 @ 2.1Ghz
Palit GeForce GTX 550ti
4gb Ram

Also if you have any suggestions on how to fix this so I wont need to buy a new psu. I'm actually low on budget right now.

I'm tired of a freaking piece of crap pc o.O

Power supplies with a single fan go exactly that way so that they remove the excess heat from the case and blow it out of your system. They are more efficient and quieter than the ones with the smaller fan at the end panel and they move more air as well. The Corsair 430W or the 500W models will be fine, the 600W model only if you plan on a major upgrade in your graphics card. That 430Watt model has more amperage on the 12Volt rail than many 600W units which makes it plenty for you since all of the high draw components rely on the 12V rail and any power supplies with high numbers on the low voltage rails is wasted and there just to be able to list it as a higher wattage model number.

You have to be a little bit crazy to keep you from going insane.

"I tried pressing the power button for 30 seconds and , still no luck"

What does that mean "turned it on again"? Did it turn on or not? Any LEDs lighting up or fans coming on?

"since it was pretty hot"

It sounds like you may have simply overheated the CPU & it shutdown to protect itself. Did you allow the system to cool down for a while before attempting to restart it again?

Yeah, I cooled it off at about 5 minutes...
I read about something that I should unplug my desktop and press the on button for about several seconds and release it. Then I tried to plug it all again but it still wont on. No fans and lights working at all... I tried the paperclip test but the psu fan didn't wind up. Does that mean it's dead?

Sounds like the psu fried. Look at any one of these Corsair psu's with a rebate right now. Most importantly pick one with a SINGLE 12 volt rail. I list the corsair line, but you can use any brand you want as long as it has a single 12 volt rail and is 80+ certified. Good Luck.

I am unsure how many watts should I get? Would a 600W work? Any PSU should work right? As long as it has 24 or 20+4 pins and a single 12v rail. What about the pcie connector? Is it 2x6+2?

Thank you!

600 should be more than enough, but Newegg has a power supply calculator on their site too. 20+4 and 24 are the same thing. 20+4 allows you to unhook 4 pins if you just need 20. most good power supplies have 2 six pin pci-e connectors. I'm not sure what the GTX 550ti uses, but you can google it to find out.

You don't need a 600W PSU for that setup. The Corsair 430W is plenty good enough. And it's on sale for $20 after rebate.

Im planning to upgrade my cpu in the future so I was thinking of a higher wattage... So a 500 watts is enough right?

The 430W PSU is enough.

The Corsair Psu you gave to me has it's fan on the top.. But my case doesnt have a hole on top since the psu is placed on top.. Is it safe to place the fan facing the mobo?

Oh. So the fan takes in air not flows it out of the psu? Okay... I'll order one now and get back if it works.
