Posted June 25, 2019 Motherboard Pegatron M2N78-LA Bios 5.10 Processor AMD Phenom 9750 Quad Core 2.40 GHz OS Windows 7 Professional - 64bit Video Card (Onboard) Nvidia GeForce 9100 Nvidia GT 430 Ram 8gb DDR2 (4x 2gb) Power Supply 430w Computer turns off (no BSOD, just powers off) about a minute after loading windows 7 normally Computer will run fine in safe mode, even under load, with no shutoffs I removed the video card and re-plugged all motherboard power, running off onboard graphics Ran Memtest with no issues on Ram Fans run fine, and replaced the thermal paste on the CPU, so I don’t think it's overheating. Computer will turn off while attempting to boot from Linux boot CD, even with main HDD removed It seems to me that it has to be a hardware issue given it won’t even boot from a CD, but the fact that it runs just fine in win7 safe mode makes me doubt it could be the CPU or PSU. It's a very old computer used only as a media device, but the puzzle of what is wrong has me stumped. Link to comment Share on other sites More sharing options...

Posted June 25, 2019 First off, please change your lext color. It is near impossible to read under dark mode. (EDIT, not sure if it was a bug, you changed it, or a mod did. But your text is normal now, so disregard this) As for your issue, it sounds like a hardware failure for sure. When it powers off do the fans spin up or does it just go dead? Brands I wholeheartedly reccomend (though do have flawed products): Apple, Razer, Corsair, Asus, Gigabyte, bequiet!, Noctua, Fractal, GSkill (RAM only) Wall Of Fame (Informative people/People I like): @Glenwing @DrMacintosh @Schnoz @TempestCatto @LogicalDrm @Dan Castellaneta Useful threads: How To Make Your Own Cloud Storage Spoiler Guide to Display Cables/Adapters Spoiler PSU Tier List (Latest)- Spoiler Main PC: See spoiler tag Laptop: 2020 iPad Pro 12.9" with Magic Keyboard Spoiler PCPartPicker Part List: https://pcpartpicker.com/list/gKh8zN CPU: AMD Ryzen 9 3900X 3.8 GHz 12-Core OEM/Tray Processor (Purchased For $419.99) Motherboard: Asus ROG Crosshair VIII Formula ATX AM4 Motherboard (Purchased For $356.99) Memory: G.Skill Trident Z RGB 32 GB (2 x 16 GB) DDR4-3000 Memory (Purchased For $130.00) Storage: Kingston Predator 240 GB M.2-2280 NVME Solid State Drive (Purchased For $40.00) Storage: Crucial MX300 1.05 TB 2.5" Solid State Drive (Purchased For $100.00) Storage: Western Digital Red 8 TB 3.5" 5400RPM Internal Hard Drive (Purchased For $180.00) Video Card: Gigabyte GeForce RTX 2070 8 GB WINDFORCE Video Card (Purchased For $370.00) Case: Fractal Design Define R6 USB-C ATX Mid Tower Case (Purchased For $100.00) Power Supply: Corsair RMi 1000 W 80+ Gold Certified Fully Modular ATX Power Supply (Purchased For $120.00) Optical Drive: Asus DRW-24B1ST/BLK/B/AS DVD/CD Writer (Purchased For $75.00) Total: $1891.98 Prices include shipping, taxes, and discounts when available Generated by PCPartPicker 2020-04-02 19:59 EDT-0400 身のなわたしはる果てぞ 悲しわたしはかりけるわたしは Link to comment Share on other sites More sharing options...

Posted June 25, 2019 How many times have you run it in safe mode? Sounds like a fluke one off thing. I kinda doubt it is but honestly these symptoms are odd af. Does it BSOD or just off instantly. Download mem test and give it a run (if it loads) maybe a fault ram stick thats particular? Sadly after that my only suggestion is a psu switch (im assuming its easier to test a new psu then a new cpu and mobo). Link to comment Share on other sites More sharing options...

Posted June 25, 2019 Author Fans spin when it powers on, it reaches windows and works normal for about a minute, powers off, fans spin to a stop. Runs in safe mode 100% of the time with no issues, even when running CPU stress tests. Memtest ran and has no faults. No BSOD, just shuts off immediately like the power switch was flipped. Does so even when trying to boot from CD with no windows hard drive connected to the computer. Link to comment Share on other sites More sharing options...

That was my thought too, a driver issue or some program, but it wouldn't explain crashing while booting from a Linux CD with no windows 7 drive in the machine right?
