Alright, so I have a bit of an older system. Video card died about four months ago, I assume it was the video card, as the display went to a checkerboard pattern, distorted color, and soon, even in safe mode, wouldn't recognize a higher resolution than 800x600. (I should also mention that when I built the computer in the first place, I discovered it had a bad PCI-e slot. If a video card was placed in it, the system would restart itself immediately after booting up. My fix was to simply put the video card in another slot and it ran fine for a couple years.)

So I got a video card for christmas, assuming this would fix the problem. However, when I installed it (in the PCI slot my old card used), it would turn on for a second, and then turn off. Wait about five seconds, and turn off again. It would keep doing this until I turned the power supply off.

I have tried installing my old card, at least see if it would boot up (which it used to) that didn't fix it. I've tried removing one or the other RAM stick, also didn't solve the problem. Removed the motherboard battery and replaced it, didn't solve the problem.

Is it the power supply? Or the motherboard?

Assistance will be greatly appreciated. Been dying to play Fallout 4

Totally makes sense. I used to be an engineer for Asus, and having to send emails to people who didn't realize that compatibility was a thing was always the worst part of my day. I don't mind being a second pair of eyes if it saves everyone money and grief.

Sure!

(I built this system in 2011, can't afford to build a whole new one just yet)

Well, the top one is broken, causes a reboot loop. And the bottom one is inaccessible because the powersupply and video card can't occupy the same space-time.

Pretty sure it's not the video card, as I've tried both of them and the computer reacts the same way. I think I need a new power supply. Current one is 750w, would I need a 950 or more you think?

Well the old card did work... kinda. Like, months ago when the card broke, it wouldn't display properly. But the system would boot up still, but no resolution was higher than 800x600, it didn't give me the option.

So I let the system sit for a while until I could get a new card. I've switched the cards out and back again and it has the same problem no matter what card I had installed: it won't stay on longer than 2 seconds. And then after about 10 seconds it tries to start up again.

Alrighty, so I just so happen to have an extra power supply and gave it a shot. I misread the power requirenents and didn't know that 550 would be enough. So I tried it and had the exact same problem.

The motherboard itself appears to be the problem.

The case wouldn't allow the big honkin' card to get into place to try the bottom slot :/

The good news is, however, a friend of mine didn't get a 3DS for christmas and I might sell her mine, if she's interested, and get the new motherboard that way.

Sounds like it could be a short in the mobo. Take the board out of your case and put it on a wood or plastic table, then hook everything up and see if it boots. If it doesn't, take out your CMOS battery, give it a couple minutes, then put it back in. A test system would be your best friend if you can find one. Don't just keep power cycling over and over. If there is a short, you could damage your card and CPU.

It's not impossible, but I wouldn't really think so. If it's dusty enough for that to be a relevant concern, it's too dusty. Take everything out of the case, give it a good clean with some canned air and reinstall it.

I'd like to thank everyone who answered this thread. New motherboard came in and everything works...

Except the hard drive. I stupidly took it out of my computer case and it somehow got damaged (SATA port is broken) in the few months it wasn't working. Just a trip to the Buy More tomorrow and I think I will have it up and running.

I had windows 7 installed on the old hard drive and can run system recovery software off of it, but I can't actually load windows without a blue screen. If I find my windows install disc (pretty sure I know where it is), will I be able to install the same copy onto the new HDD?

Edit: Was expecting to need to buy a new copy of windows 7 but authenticating went smooth. PC is up and running perfectly! Thanks again for all the help and guidance!
