I have a custom built PC that is exhibiting some...odd... behavior, something I've never seen before. It was working fine one day, and the next day, it wouldn't start. Seeing as I wanted an upgrade anyway, I purchased a new motherboard that was compatible with all my parts. While replacing the motherboard, I accidentally damaged the CPU. Well, I wanted a new one anyway... so I got a new one. Seeing as I was replacing a ton of parts already, I bought a new PSU because the old one was super loud. When I slapped it all together, it starts up, lights, fans, drives, they all start. But I get no display from the monitor. No beeps, which I believe means it doesn't POST. I figured it was the RAM, because after removing the sound card and graphics card, there was nothing else that I hadn't replaced. When I remove both sticks of RAM, I get a continuous beeping, and according to the mobo handbook, means no RAM. So I think the mobo is functional, or atleast partly. I bought new RAM, but it still didn't work. I tried 3 monitors, with both VGA and DIV. So it's probably not the monitor, either.
Now, let me get to the random part. Every 20 or so boots (I should also mention, for about 3 out of 5 boots I have to unplug the PC because it won't powerdown via the button), it will POST and I'll get display. Then, after about 2 or 3 resets, it won't work again. This confuses me so much, because even when I change nothing, it will/will not work. My thought is that maybe it has something to do with the RAM not clearing or something. I also reset the CMOS battery, incase that had anything to do with it, but no eval. I found some weird suggestion online about holding the power button for 30 seconds while it was unplugged. That did nothing, but I didn't expect it would...
I've replaced just about the entire computer, and all the parts are compatible. Done about everything I can think of, but nothing has worked. Hopefully someone can help me here.
And as I side note: When I do get my computer to boot, it says my hardware has changed and I have to re-activate windows. But it says I have to call Microsoft to do it. So I get this fancy automated voice that asks me to enter in a code into windows, then it asks me "How many computers have you activated with this copy of Windows?". Well, I had it on my computer before I replaced everything, so I said 1. Then he yelled at me for violating my 1-use license. I dunno what's going on there, do I have to re-purchase Windows 7? And they wonder why people pirate software... That's just a bonus question, though.
- 8GB of DDR2 RAM (Corsair)
- AMD CPU (I don't know what GHz or model because I can't find the box... (I think its 4 cores of 2.8Ghz)
- ASRock A785GM-LE Motherboard
