Hey folks,
I'm currently investigating a custom built PC that is having some issues that I believe are related to the power supply. Upon booting, everything seems pretty normal. However, when graphically intensive programs are run, from games to say Photoshop, there's a pretty loud buzzing noise coming from the case. At first thought, I figured it was the GPU since it only occurs when intensive graphics are being drawn, but when I opened the case and listened, the noise seems to be coming directly from the fan in the power supply.
I did some research and thought it could be coil whine, so I started using it to see what would happen. After about 3-4 hours of running more graphically intensive programs, the PC powered down unexpectedly. No damage seems to have been caused, but its definitely something more intensive than coil whine.
Here's the current specs of the PC:
- Intel Desktop Motherboard DP67BG
- Nvidia GeForce GTX670
- Intel i7-2600K processor
- 12 GB DDR3 RAM (can look up specific type tomorrow if necessary, don't have access to machine at the moment so this is all from memory).
- Thermaltake TR2 RX 750W power supply
- 1 DVD/CD drive
- 2 Solid State drives
- 1 HDD
Unfortunately the Thermaltake 750W power supply is not new, it was given from a friend that didn't use it anymore, but it already had extensive use and he wasn't sure what shape it was in. First thing I tried doing was switching the power supply over to a Corsair 650TX power supply (650W), but it won't even boot to BIOS when I use this power supply. I tried switching out the GPU for a less intensive GPU (tried a Nvidia GeForce GTX560) but still the same results. I also tried removing all but one SSD (the one that has Windows loaded on it), and removed some of the memory down to one stick of RAM, but that also didn't help.
I recently tried flipping the jumper switch to reset the BIOS, but that didn't work. I thought about resetting the CMOS by removing the battery and letting it lose it settings, but wasn't sure if that was the next best step or if I should try other things first.
I can still get the computer to boot by switching back to the Thermaltake 750W power supply, but it refuses to post to BIOS with the Corsair 650W. I could be wrong, but I feel like the Corsair 650W should have sufficient power to run everything, much less when I removed 2 HDDs/SDDs and bumped the GPU down a bit.
I unfortunately don't have anyone around the area that I could use to test parts with, and while I believe its the power supply, I'd like to try to solidify that guess a bit more before I run out and get a replacement just to have it not post to BIOS as well. Any thoughts?
Thanks
