I'm running an Asus P4C800-E Deluxe motherboard with 2 x 512mb of ram. A few months ago I got another 2 x 512mb sticks of ram off a friend who had recently upgraded. I still had 2 vacant slots for ram on my motherboard, so I put these 2 new sticks in along side my existing ram. I thought this would give me 2gb ram total, but instead, I turned the computer on after the ram was installed and it started up just as normal, but the screen remained blank. It was like the monitor wasn't getting any signal from the computer. So i turned it off and removed the ram I had just put in, then started the computer up again and it worked fine, just like before. They were both DDR1 ram. So it seemed that ram problems can cause the monitor to not recieve a signal or something?
Keep all of that in mind for my current problem.
So months after all of that happened I decided it was time to upgrade my ram properly, from 1gb to 2gb. So I bought 2 x 1gb sticks off the internet. When they arrived, I took out my old ram and installed the new sticks. I started the computer up and I could smell smoke. When I looked I realised that one of the sticks hadn't been clipped into the motherboard properly. So me being an impatient idiot had caused the motherboard to start smoking. I quickly turned the computer off and gave it some time, then I put my old 1 gb of ram back in. Once I started it up again, The monitor remained off, just like before. And this was with my old ram that used to work! So I assumed that the new ram I had purchased and the motherboard must have been burnt out by me and my imcompetence.
So time went on and I decided to by a new motherboard and ram hoping this would solve my problems. My Asus P4C800-E Deluxe motherboard is a few years old now, and not in production anymore. So I purchased a second hand, refurbished one off ebay (If I bought a completely new motherboard I would have had to buy a new processor and everything). I also bought new 2gb ram DDR1.
When the items arrived, I put the new motherboard and ram in, and all the other components. And when I turned it on it did the same thing again! No signal to my screen, but the computer sounds perfect! Feeling very annoyed, I tried a number of things, but no success.
I've tried 2 other graphics cards, a different processor, a different monitor and a different hard drive. With no luck.
So i'm wondering if anyone has any advice on what this problem could be. Any suggestions or help would be great!
Thanks a lot guys, muchly appreciated!
