Alright, so I just joined this forum specifically because I want help with this issue. I -really- want to get it fixed and I'm currently praying that it's something that can be easily fixed without spending an ounce of cash.

Here's my build at the moment.
GPU: Radeon r7 260x Sapphire, 2GB OC edition
CPU: AMD FX-4300
Motherboard: ASUS M5A78L-M LX PLUS AM3+ AMD 760G Micro ATX AMD Motherboard
PSU: Antec VP-450 450 Watt Energy Star Certified Power Supply
RAM: Crucial Ballistix Sport 4GB Single DDR3 1600 MT/s
HDD: Seagate Barracuda 500 GB HDD SATA 6 Gb/s NCQ 16MB
Case: Rosewill Dual Fans MicroATX Mini Tower Computer Case FBM-01

So, I recently built a gaming computer about a month ago. Everything went fine with the build and it was, overall, a good experience. About two weeks back I took a look at the interior of my case and frowned at the wires I saw. It was -certainly- not helping air flow and it may have been one of the reasons that artifacts appeared in my games after a while of play.

So, I took it upon myself to rethread the wires so it'd be neat and help air flow. Unplugging the case from the power supply, I pulled the wires back around the other side then plugged them in all properly (of course I touched something metal beforehand so I wouldn't have to worry 'bout static). It was a bit of a difficulty trying to close the other side of the case after that, but I managed to get it done...

So I was playing on my computer, having a good time... when I suddenly heard what sounded like a "click" (that frequently occurs when I press the power button to turn the computer -off-) and my comp just up and died.

I panicked, thinking that it was something like the case panel pushing too hard against the wires and causing them to -snap- or something. I opened it up and after a bit of work I put all the cords back to their original... not so good position.

It was working fine for a while after that, but then shut down again, making me worry that I damaged my cords permanently or something like that. However after a while (and me stuffing the cords as a tangled mess as far from the fans as I could) it started working once again.

Now my PC usually performs a diskcheck on startup. One of the weird things I've noticed is that it seems to follow a pattern when it dies. Which makes me think this may be a software error of sorts. It usually dies after loading to a certain percent on startup and when I use Startup repair it always dies at the exact same time. I'm being earnest, I started my computer up and used startup repair each time... each failure was within about a second from each other.

So, can anyone please help? I'm seriously worried for my comp!

It could be several things.

It could be a blown capacitor on your motherboard. I have seen this happen before, but on older motherboards. That does not mean it cant happen to a new motherboard. I would visually insepect the motherboard to make sure this has not happened. When i encountered this, the errors that were coming up mad it look like it was a bad stick of RAM, until the blown capacitor was discovered.

Your video card requires a power supply of 500 watts. That is coming from the Sapphire website...

So it could very well be that your powersupply is just not enough watts.

Huh, well the PSU worked fine before when it came to running the graphics card, but I suppose I should give you guys an update.

I tried moving the PSU wires around on the optical drive and HDD, it actually would start up without shutting down this time! I ran start up repair, it was working fine... yet around 35% the computer would shut down to configure the updates. It would restart as though everything was normal then state "failed to configure windows update.

The motherboard shows no visible sign of damage, so I'm thinking that the cause of this -could- be something as simple as the wires to the HDD being twisted. At least, I'm -praying- that's the solution.

Good news everyone! I messed with a few wires around the HDD and it was a full three hours before it started acting up again.

I decided to use some other wires to connect the HDD and disk drive to the PSU (I have, far and away, an excess of wires with this thing) and it hasn't died yet!

I remain cautiously optimistic about this now. I wanted to thank all of you for the help! I appreciated it more than you know!
