- ASUS M5A99X EVO R2.0 AM3+, AMD 990X, SATA 6Gb/s, USB 3.0, ATX, AMD Motherboard
- AMD FX-8350 Vishera 4.0GHz (4.2GHz Turbo) Socket AM3+ 125W Eight-Core Desktop Processor FD8350FRHKBOX
- 6 to 8GB of Corsair 1600MHz CMP4GX3M2A1600C9
- 650W Ultra ATX Power Supply (ULT-LSP650P)
- 240 GB Mushkin SSD (OS), 1 TB Samsung HD103UJ, 1.5 TB WD15EARS, 3 TB Seagate ST3000DM001
- SAPPHIRE Radeon HD 6850 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready
- Windows 8 64bit
I installed 2x8 GB of G.Skill Sniper F3-1866C10D-16GSR, then booted up the computer. It made it past bios and immediately shut down. Every boot since then has been an immediate on-then-off. I have done the following:
- Reset CMOS (battery and 1-2/2-3 pin reset)
- Revert to old RAM.
- Use one stick of RAM (old and new)
- Flash back BIOS update to the latest
- Remove extra HDDs and graphics card
- Disconnect all hard drives and graphics card
- Replace PSU
- Reseat graphics card, RAM, CPU
- DirectKey and MemOk
- Swap CPU
In some of the cases, the computer will start then stop (fans and LEDs start then turn off immediately). Without the GPU, I can get the system to start, but CPU_LED light is solid red, all fans are running at maximum RPM, and there is no output to the video card (I had to use a Radeon X1550 to reach this point).
I am out of ideas at this point. Is it possible I fried something?
Edit: tested with alternative CPU, same behavior.
Cases (unfortunately, there is no native video for the motherboard):
- CPU / NO RAM / NO GFX : Boots, CPU_LED red
- CPU / RAM / NO GFX: Boots, CPU_LED red
- CPU / RAM / X1550 : Boots, CPU_LED red, no video output
- CPU / RAM / 5770 : On-then-off
- CPU / RAM / 6850 : On-then-off
RAM in these cases is either old or new, the behavior appeared the same.
It seems like the 650W PSU has died, but with a replacement, I am still getting boot issues. I am RMA'ing the motherboard.
GPU tested on another system and failed. Is it possible that the RAM addition fried my entire computer?
Edit #4: RMA'd the RAM as defective and was approved for a refund.
