About a week ago I started noticing a burning smell in my room and quickly deduced that it was coming from my PC so I shut it off for the night. The next day I took out all of the components, cleaned them, cleaned the fans and the motherboard and inspected everything for signs of burning. The only thing I noticed was a stronger smell around the PSU. I re-assembled, booted (with the side panel still off) and everything was fine. The burning smell started up within 3 or 5 minutes and at this point I was already purchasing a new PSU off tigerdirect. Within seconds after finalizing the purchase, poof, a pop sound came from the PSU and a small column of electrical smelling smoke came out from the PSU.
Fast forward three days. I received the new PSU, hooked it all up. The motherboard green light comes on. I tried then tried to boot. No keyboard or mouse lights come on. The GPU fan sounds like it is spinning a little faster than usual but this may be paranoid bias. No image being transmitted to the monitor. Probably most importantly, I noticed the CPU fan spin for about 2 seconds weakly and then stop all together.
I googled the issue a little and come across this advice:
---------------------------------------------------------------------------------------------------------------------------
1) Disconnect the power cord from the back of the computer & open up the case.
2) Wear an anti-static bacnd or at very least discharge your static by touching a metal surface
3) Disconnect the main 20pin ATX power connector from the motherboard & the square 4pin ATX2 power connector
4) Remove any PCI cards you have & disconnect ALL drive cabling from the MOTHERBOARD. Also disconnect any internal USB fly leads from the motherboard.
5) You should now have ONLY the cpu+heatsink/fan, memory & video card installed. Locate the round silver battery in the bottom right corner of the board. Just below it, you'll see a plastic jumper cap. This cap should be covering 2 pins (pins 1 + 2) with pin 3 bare. It will be marked JP1. Move the jumper to cover pins 2-3 instead. Leave in this position for about 30 seconds, then return the jumper to its original position (pins 1-2).
6) Reconnect the square 4pin ATX2 power connector & the main 20 pin ATX power connector. Make sure that the case speaker or buzzer is connected also.
7) Make sure the only external devices connected are the keyboard/mouse & monitor. Reconnect the power lead & power on the system
---------------------------------------------------------------------------------------------------------------------------
I followed these directions and tried to repower the system. Upon trying this I notice a slight change in behavior of the PSU fan. It now rotates ~30 degrees every quarter second or so, spastically, for about 3-5 seconds and then stops all together.
I have no idea what to do as I really depend on this computer heavily for my senior classes at university. I thought replacing the PSU was going to be a fix and maybe it would have been but I am guessing that the PSU frying out may have overloaded and fried some aspect of the motherboard, the CPU itself or even the GPU. I am clueless as to what to do further.
Computer was built ~6 years ago. Everything is from the original build except for added RAM (about 1 year ago)
Computer specs:
Motherboard: M4A79XTD EVO
CPU: AMD Phenom II X4 955 Black Edition
GPU: ASUS Radeon HD 5770
RAM: G-skill ripjaw series (3 sticks combined 10 GB)
PSU that fried: OCZ StealthXStream OCZ700SXS 700W
new PSU: Cooler Master eXtreme Power Plus 550-Watt ATX
My strongest suspicion is that the CPU got fried. Should I do further tests to confirm this before I go ahead and get a replacement. Is it recommended I just get a new mobo, cpu and gpu altogether (this would suck) ? I would like to be able to game again if any of these are the case I would also greatly appreciate any suggestions on current GPUs, mobos and cpus that have a lot of bang for their buck!
Thank you so much for taking your time to help me out.
