So hello, i've got this problem

I bought a mobo and cpu for about $130
It was ASUS M5A97 Pro rev 1.01 and AMD FX6300

So i hooked everything up, started the pc, but the GPU wasn't moving
No beeps no nothing

So i noticed this solid red CPU led right next to a CPU
(i never saw this anywhere), so i start looking it up
Mostly people said that its a CPU problem, it has bent pins or it didn't sit right in the socket
Now, i looked for bent pins and there were non of them

THE BIG THING IS!

I managed to start it! I accidentally read something like "fast switching it off and on"
i did some experiments

When i start pc, everything is spinning, hard drives, CPU, PSU, but not the GPU!
But i noticed when i switch it off (by PSU), the GPU moves a bit!!

So i remembered that fast off and on

1. Turn the PC on
2. Pull the psu switch off, until red led is off
3. Pull the switch fast ON, and GPU moves a bit
4. Then red led blinks twice or three times and GPU starts moving and it finally gives me the beep and boots into windows



now i know this sounds weird, i actually made a video for you guys to see waht's going on
Here's the link:

I even updated mobo bios, with latest one

Now this is very weird, like something is blocking CPU from reading on..

I never knew what this red led was, but when i start it ok, i goes through CPU, then memory, then GPU and then bios

It's like a little check mark, like, yeah CPU is alright, memory's fine, yup, GPU rocks, bios okay.. and then its windows...

I have no clue..

Maybe something electrical? Capacitors or something?

Here's a video from another angle:

I tried with diferent cpu, different gpu and rams
status quo

I have :
FX 6100 (turns out dude sent me wrong one)
ASUS M5A97 pro
R7 360 2gb ddr5 oc by gigabyte
2x4 Ballistix ram working on 1600mhz

I didn't knew in what thread should i post this, sorry for that

Now sorry my english, i'm from Croatia
 
This definitely feel like capacitors or PSU. in my case first start died around post time ( beep sound) and everything turned off. When I pushed button second time everything booted normally. Problem was with faulty PSU that did overcharge MBO.
You sure have to check PSU, and possibly directly search for this MBO problems. ASUS forum might be place to look.
About CPU, I think burned one can have similar problems, not sure, but if it booted then benchmark it. Should die in progress or show really bad results.


if the problem is with capacitors turn machine off. pull power cable and keep pressing on button few times, leave it for 5 min. If problem will repeat itself then its very likely capacitors problem.
 
It's not the PSU, i checked it with 3 different PSU's

I also tried with different CPU and different RAMs

It's probably MOBO, but it can run when i do that trick

I'll try this CPU benchmark, what benchmark should i use?
