EVGA nforce 590 sli, buzzing sound
Hey everyone. Ive been having this problem for quite some time. Every once in a while.. usually while I am gaming and my comp gets hot, my computer will make a loud buzzing sound for about 1-2 seconds and then (usually) reboot itself, sometimes it won't reboot if i hold my mouth just right. I can't tell if the sound is coming from the power supply or the motherboard, but does this sound like bad caps? Another weird this is, i'd been getting bsod's, so i took out a stick of ram one at a time until the BSODs stopped. When i tried to put the ram back in (hopeful thinking), the computer wouldn't boot and would stick on the "finding ram" post code. I dont have another motherboard to test this ram in, but why would my ram just go bad all the sudden? Or is that a symptom of Bad caps, perhaps powering 4x 1gb sticks of ram is too much for some bad caps?
None of the caps on my motherboard have any visual signs of plague, I know that doesn't mean they aren't bad.. but I don't have an ESR meter yet, so I thought i'd ask if anyone else had symptoms like these with bad caps. My power supply has a lifetime warranty, so im not gonna open it up. Thanks a bunch!
edit: oh the power supply is an Antec Truepower Trio 650w.
