No POST, RAM is okay. Unsure about Motherboard, CPU and PSU.

I've recently had a problem where my PC doesn't post. No video signal out at all but all fans are okay. I have tried a different GPU but the problem is still there. The problem started after I opened my PC and removed and reinserted the RAM. I have since had a friend check the RAM and he said it was fine. To my understanding the remaining causes of the problem can be either one of the motherboard, PSU and CPU. I have removed the everything from the motherboard and put all the parts back but alas I still have the same problem. If there is anything wrong with either the motherboard or the CPU I am planning on replacing both parts, but I don't want to replace the parts and then realize that the PSU was the problem.

Is it possible that the pSU is my problem and how big is the chance? What I can tell the PSU isn'y usually the problem in these cases but I am looking for a second opinion. Any help would be greatly appreciated.

Thanks in advance! :) 

EDIT: Forgot to mention that the DRAM light is solid red. When hrld for about 2 seconds it starts flashing faster and faster for about 30 seconds but then it goes back to solid red.

HI
Start you PC with ZERO ram installed
If you hear beeps errot then you Motherboard might be ok - it`s detect missing ram ...
Next one is to disconnect all HDD , DVD ,,
Start with only One RAM module installed
Check them all one by one
If you still not get POST - motherboard is good suspect

Try to clear CMOS - jumper clear

Hey, I've tried all that excluding resetting CMOS with the jumper solution since my MB lacks the jumper reset for CMOS. But when trying all the solutions the problem remains the same. Sadly I don't have an internal speaker to troubleshoot with. Any ideas?

This is incorect state - you mobo HAVE CLRTS jumper !
this is the manual :
http://www.asus.com/Motherboards/M4A89GTD_PRO/#support
go to page 2-21 - Jumper - Clear RTC RAM
- follow the steps

report back after CMOS clear

But what is the difference between resetting CMOS by removing the battery and resetting CMOS with the jumper? I have reset the BIOS by removing the battery.

Well removing the battery will have the same effect on most of the mobos.
I advise you to folow the CLRTS clear procedure as it`s described in the manual.

If you still experience temporary fix you may change you mobo battery
If the problem is there again you may start to worry about you mobo.
In tha last scenario i`ll go for PSU test with known good one
At the last place you must test you CPU on different Mobo.
Is not bad idea if you manage to run you sytem - try to upgrade the bios before you go for Motherboard R.I.P
Also make visual inspection of the Motherboard for visual BAD capacitors .... it may be the the problem at the first place :)

I replaced the CPU and the motherboard and everything is working as it should now!
