First off the computer specs,
E8400 core 2 duo
BFG GTX 260
Corsair 650w PSU
4 Gigs of ram
I have been having computer issues for over two weeks now and I am at my wit's end.
My problem started when i accidentally tripped over my surge protector causing my whole setup to lose power so I immediately tried to turn power back on for the whole setup and to no avail. So after researching what could have happened on my droid I found out that it might be a PSU or motherboard problem. So I went to newegg and bought a power supply which is similar to my corsair, tried it out and computer still would not turn on (no POST, no external lights or mobo activity). So the next logical step I considered was a new motherboard and got the same exact motherboard, tried it out and still nothing happened. Then my friend tried benchtesting the motherboard and still nothing happened and then he also tried plugging in my mobo to another desktop which worked(a big relief).
After finding out it was the whole front panel that was faulty, I RMA'ed back the motherboard and PSU since both my old stuff still works fine and theres no point having the new stuff around. After getting a new tower, another set of problem ensued. Power keeps cycling on and off and its by random if it ever decides to legitimately turn on. I am pretty sure I have installed everything properly though cable management may be lacking. What I have tried doing is removing the PCI-E and see if it would boot up without it and still goes through a couple cycles and would systems let the system boot up. So after that I turned the power off, remove power plug reseat the power to the graphics card and it booted it up properly this time (which could still be a fluke.)I've also googled this issue to death and one of the probable issues was that there the CPU voltage isn;t enough and I don't know how much to increase this by since messing BIOS settings is beyond me.
Thanks for all your help and its very much appreciated.
