Question Disclaimer: Howdy. I've been browsing the forums for the last hour and a half looking for a similar problem, so first let me say that I'm really sorry if you have answered this question a million times. I kept finding related questions, but have tried everything I have read and still haven't fixed this problem.
My Amount of Technical Knowledge: This is the second time I have ever built a PC from scratch in the past 8 years, so I don't know all the acronyms and such, but I feel i know enough to at least answer any questions you can pose.
My Problem: My computer will randomly (with no set pattern) lose power for 3-5 seconds and then just restart itself. Upon restart, it shows me the options for how to restart windows (in Safe Mode, in Last Known Good Configuration, or Normally). Sometimes upon losing power it will not restart, and pressing the power button on my case causes the case fans, CPU fan, and Video Card fans to stutter but not start, and the computer does not power on. If I reset the power supply for 15-20 seconds and try again it will start most of the time, but on certain occasions it won't start at all.
My Computer Build:
CPU -- Intel i5 2500K
Motherboard -- ASRock P67 Extreme 4
RAM -- Corsair Vengeance (2 x 4GB) Low Profile
Graphics -- MSI GeForce GTX 560 Ti - 448 Cores
Storage -- 1 old Seagate 1TB drive. 1 old Seagate 300GB drive.
Power Supply -- XFX Core Edition Pro 550W
Case -- [strike]My old Antec 900[/strike] Changed to Antec P280.
Optical Drive -- ASUS DRW-24B1ST
Heat Sink -- COOLER MASTER hyper 212 Plus
SSD -- Intel 320 Series 80GB SATA II (MAIN HD)
NOTE: If you need links to the exact parts I bought, I have them. Parts are from NewEgg.
History of Troubleshooting:
1) Computer worked fine upon first build and lasted 3-5 days without a shutdown during heavy usage (Addiction to SWTOR).
2) Around day 5 the computer starts to randomly lose power. This happens when I have SWTOR and Steam up. I assume that is the problem and don't run the programs together.
3) Day 6 - Computer starts to power down multiple times in a row (3 to 4 times) but then works fine for the next two days. I did not restart the system during this period. The system could have rebooted itself when I was away at work and I would not have known as I leave no programs running when I leave it.
4) Day 8 - The computer finally won't power on at all after a power down, and I get the fan twitch error mentioned above.
4a) I discover that holding down the power button on my old beat up case as hard as I can will start everything up fine and assume the button is the problem.
4b) I buy a replacement case (Antec P280), disassemble the computer from the 900, and reassemble it in the new P280 case. Everything again works fine for the next (1) day.
5) Computer starts to randomly lose power again.
6) Come to Tom's Hardware forums for help.
7) I have done all 23 steps in the checklist of troubleshooting a new build that won't POST (I'm not 100% sure what that word means BTW). Everything was OK. I am currently running Memtest86+ because I saw a thread about it.
8) I am now posting here for help.
I'm sorry for the super long message, but I assume the more information I post the better. If anyone needs more information, please let me know. If this is the wrong forum, please let me know.
For anyone that made it this far, Thank you so much for reading!
