Hi everyone, hope I'm asking in the right section

My pc seemed to stop working after installing my new fan Cooler Master TX3 EVO.

Things in cronological order:
-Changed PSU, went from a very low tier one to a Fortron PPA5005003 "Hyper" 500 W (http://www.amazon.it/FSP-Fortron-PPA5005003-Alimentatore-colore/dp/B00LMBSTTA?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s01)
-Tested booting/shutting down several times, all went good, Pc was working properly
-Changed the CPU fan to get more reasonable temps (

-Pc was turning off by its own on start up, nothing different with entering the BIOS and using windows startup repair (this screen -> https://wpcf.neosmart.net/sites/5/2013/08/Windows-failed-to-start.png)
-Reinstalled the old fan, PC booted properly w/o shutting down, all seemed to work properly again
-The following day I tried to reinstall the old CPU applying the thermal paste better, was wondering if those shuts down were because the CPU was getting to its Tcase (100 °C).
No video signal from the monitor
Fans were spinning
Pc was shutting down by itself within 10-40s
-Reinstalled old fan
No luck this time
-Reinstalled old PSU
Same
Tried to see if those self shut downs were still there, after mounting the old fan and PSU again,it seemed like it was more like a matter of 10-20 mins
Once happened that I accidentally unplugged the monitor power chord (while it was on), PC immediately turned off
-Tried booting w/o hard disks/readers, case fan and just with a stick of RAM (tried with each stick on each slot)
Nothing
-Tried another 100% working old monitor (so different power chord, VGA cable and monitor itself)
-Tried to short the second and third pins which seem to concern about CPU fsb speed
(The mobo manual says "Short pin 2 and 3 if using a 1333 CPU, otherwise the system may not work properly). First and second pins were shorted before.
-Tried resetting CMOS twice
1)Using a paper clip (instead of a jumper, I think I lost it) to connect those 2 pins with it for 5-10 s (as the manual said). Nothing different
2)Took out the battery for 50-60 mins, placed it again and shorting those headers like previously
Both times with the PSU's power chord unplugged and probably turned off
-Tried using a very old video card
Accidentally broke the white plastic thing of the PCI-E, so not sure if I insterted it correctly
No luck ;_;

My specs:
Motherboard -> Asrock G41M-VS3 R2.0 (Socket 775) - 1 month old
CPU -> Intel Core 2 Q9505 @2.83 GHz 1333 MHz FSB speed - Bought "used, almost new"; 1 month old since then
RAM -> Kingston 2x2 GB DDR3 1333 MHz - 3-4 years old
GPU -> none (Integrated Graphics)

Also:
- There's a bent pin on the socket; its placement is a VCC/VSS one, a redundant pin for supplying power according to Intel datasheets of the Q9000 CPU series

The CPU don't seem damaged
(tried my best ->www.4gp.tw/ba3u/1459547457948.jpg)
- The Mobo sadly took some screwdriver hits (not really hard ones), mostly on the pure PCB, sure not on sensible parts
-Tried to be aware as much as possible to static electricity. Wore proper clothes and touched every 2/5 mins the metal of my chair/case/power supply if turned off

Sorry for eventual mistakes, wrote this on mobile.

I'd like to be sure at least on what's not working

Any kind of help is absolutely appreciated, thanks : ))

1| Bad PSU , swap it out immediately
2| It's never a good idea to run a system with a bent pin on the CPU socket as it can and will cause an issue on the CPU and later see all sorts of issue like sudden shutdowns as you've stated above.
3| You're best option right now would be to borrow an LGA775 motherboard that supports both your Q9550 and DDR3 1333MHz ram and see if you can at least get to your desktop boot screen. Speaking of desktops, what OS are you running while you're working with the above spec'd hardware?

Sorry for my very late reply : (
The bent pins were the problem.

I took the PC to someone, he managed to partially fix them, saying that they aren't really stable and taking (correctly) out and on the CPU again could result in the PC not working again.
Since heatsinks and coolers apply a good amount of pression on the CPU I'd like to know if changing cooler could potentially result in this problem.

Is also the Fortron a bad PSU?


(Thank you very much for your help : )
