- Intel core 2 quad 2.4 GHZ
- 4GB RAM DDR2
- Old motherboard, from 2006/2007 I think
- Corsair H70 water cooler

Hello Hexero;

What PSU and what motherboard?
What does happen when you boot your PC?

 

[hexero]

Hi! Thanks for a fast reply!
I don't remember the brand, but that brand does not exist anymore, but made very popular motherboards.

The PSU is a Corsair AX 850.

When I boot the computer it happens the same as always. All the fans start etc. No beeping, but it has never been any.

Try pulling the little battery on your motherboard out for a couple minutes and see if that fixes it

Even without the monitor you should be able to tell if the system has finished the boot and loaded windows. Even if you can't see it on the screen. HDD disk activity and the like.

Will try those things, thanks.
But what could the problem be, any guesses?

No idea what's going on in your system yet.
Probably not a power supply issue....not with a Corsair AX 850.

Here's my computer booting. I just came to think of that my HDD indicator isn't connected or something, so that won't help me.

But! On the end, I filmed a thing that shows how far the PC has booted, and it's stuck at C1 or something. Normally it's up at 70 when it's fully booted. May the harddrive be the problem?

What does your manual tell you about that C1 diagonastic code?

 

[hexero]

I'm at a LAN atm, so my manual isn't here. I opened up my comp, and found the model name. It's a "abit IP35 Pro".

So I searched at google for "abit IP35 Pro c1":

And I found a guy with the same problem; no usbs working, screen is black, etc.

Turns out it's the RAM then?

Thats the first place to start troubleshooting.
Test with 1 stick at a time. And you can test more than just 1 slot in case a slot went bad.
If you can find 1 stick that is good, you'll probably want to pick up at least 1 stick that matchs the boards specs.

Borrowed my friends DDR2 RAM, and now it works! Thanks for the help!

Glad it turned out to be that simple and not a major expense to fix.
