No POST/Display after Overclocking

[Kevv233]

So I got a used pc and for the last two months it was working mostly fine until (dumb me) tried changing the settings in the BIOS to (Core Unlocker + Overclocking of +4% to try), before this I usually used the Core Unlocker feature alone (though every so often it disabled itself for no apparent reason).

---

 

Things I noticed:

The system starts, and the fans start spinning, but there is no beep and no screen output.

The PSU fan makes a strange sound but stops after a while (it did this before, but I ignored until now).

The CPU Socket is slightly dusty (but it seems that the CPU still did contact in the past).

 

Specs:

MB: Asus M578L-M LX3 AM3+

CPU: Amd Athlon II 160u

RAM: 4GB Kingston DDR3 1333MHz (2x2GB)

PSU: BRB ATX 550w X 24 P 1S

 

What I tried:

• Removing RAM Sticks and replacing both RAM sticks with a single 2GB module (in both positions).
• Connecting system speaker to hear error codes, but no error codes.
• Removed RAM and CPU to hear error codes, but nothing.
• Removed CMOS Battery for 30s to [hopefully] clear all settings.
• Tried shorting the pins instructed in the motherboard manual (I may have done it incorrectly, though).

 

I was thinking of getting a multimeter to check PSU like what it said the README, and cleaning the CPU Socket with compress air. Thanks guys for your support

try a different psu

But the fact that it doesn't give any beep code for no ram is kinda a bad sign

Try removing CMOS for 5 min with PSU off
