I need help about my PC

ok pajd tanan until After nako g.disassemble nako ako PC to clean it (removed videocard, hdd, psu) then placed everything back, dili na mo boot ako pc..

Mu ON siya (tuyok fans sa CPU and vcard and mka feel ko ga dagan ang HDD., but akong monitor mu ingon "NO SIGNAL" + wala power(lights) ang Keyboard and mouse. dili cya mu post.


Mao ni ako specs:
Phenom x4 9550
MSI k9a2-cf
Kingston ddr2 2gb 800mhz
Coolermaster realpowerpro 550w
Seagate Barracuda 120gb HDD
AOC 21.5" led monitor

ive tried a lot of things but i don't know if na try na nako tanan to diagnose the problem..

What I did,

1. Rechecked all cables - and yes, sakto connection tanan.

2. Replaced videocard with ATI 6870 - wala gihapon signal sa monitor

3. Replaced motherboard with Asus m2n68-se and placed the processor - tried On-board video(wala gihapon) -tried both videocards(still wala gihapon)

4. Tried removing the Hard drive - still dili gihapon mu boot ( no signal gihapon ang monitor )

5. Tried the VGA and DVI connections - still wala gihapon

6. Checked monitor (VGA'd my laptop to my monitor and mu display mn cya) - so dili monitor ang problem..

7. Tried removing the RAM - but No signal to my monitor still.

8. Tried placing the RAM on a different slot - still nothing..

9. Disassembled everything (out from the case) then put the parts together WITHOUT the case - still no display - rule out nako ang Grounded nga Casing na..

I hope maka help mu guys - ka2 mga experts and pros.. help hehe

Disassembled everything (out from the case) then put the parts together WITHOUT the case - still no monitor signal/display , no power (lights) to keyboard and mouse - so dili grounded ni..

any more idea(s) about this problem guys... I'm thinking Power supply or Processor?

[werty]

-pull-out psu
-test psu with voltmeter if hatag pa bag sakto na voltage each pin...
-short green(power-on) and green pins to power it...

report back if voltages are OK

[PROBLEM SOLVED]

Had it checked sa PC EXPRESS North Recla.
Turned out twas a DIRTY memory (he only had to clean the gold plated pin sa akong memory kay nag build up na daw ang hugaw didto).

Good thing erasers(for cleaning) we're made... Saved me a lot of bucks (since I was thinking of buying a new PSU lol) - I guess they're not only made for pencil errors hehe

Total cost for repair: P150 pesos.

thanks for the helping effort guys... Happy New Year!
