Help With Athlon X4 645

post #1 of 11
Thread Starter 
So I downloaded Planetside 2 last night and tried it out. It was a lot of fun but my computer wasn't running it very smoothly. The game claimed that my Athlon X4 was bottlenecking my Radeon HD 6790 (not the best gaming set up, I know). This morning, I tried OCing my CPU from 3.1 Ghz to 3.3 Ghz. Apparently, my computer didn't like this because my computer didn't start. My monitor just displayed "NO SIGNAL". I thought "No big deal, I'll just reset the CMOS". My computer started but only showed a black screen. I reseated the RAM and the video card but that didn't solve my issue. Can anyone suggest anything that might get my computer to boot? I've tried everything I know.

Man I was expecting some responses...anyway I swapped out the motherboard and the RAM and it still is giving me the same issue. So now it's down to the video card, CPU and power supply.

What power supply is it? It's model, wattage? Let's hope you didn't over stress it by overclocking that tiny bit.

Try taking the graphics card out, boot up your computer and use the onboard for a bit and get into Windows to uninstall it. Then reboot install it back.

*if you have ddr3 1333 ram and didnt lower its frequency to 1066 before you overclocked,
you could have killed the ram.

*Try using a different stick of ram from another computer.
CPU's are very sturdy and wont get damaged by a small amount of overclocking.
I also doubt the motherboard is damaged because my Athlon X4 has been running at 3.3 Ghz with 1.39 vcore on a cheap 3+1 motherboard for more than a year.

Dont worry about the Athlon X4 bottlenecking your HD6790.
My HD6850 used to be in my Athlon X4 rig and there is little to no fps gain from upgrading to FX6100 at 4ghz.

...what are you talking about o_O
The only thing that could kill RAM is too much voltage and thus frying it.

I bought this PSU used from a friend a year and half ago for $10. It's a 750 watt Coolmax CUL-750B. My computer doesn't have onboard graphics. It's weird because my monitor recognizes my computer but it just displays a black screen. I've tried switching monitors and i got the same result.

I did not change the clock or the voltage of my RAM. I also swapped it out with an extra set that I had and still got the same result.

Ok guys, I got it to boot. I swapped my PSU out with a 250 watt I had in an old dual core PC and, knowing the 250 watt wasn't enough for my Radeon, I used an nVidia GeForce 9400GT. My friend is coming over this weekend with his PC so we can see which part is acting up. My money is on the PSU.

I would say so as well. What psu is it? The power supply is a component that you shouldn't skimp out on.

Those should be fine if you don't overclock. If you do, go for a higher end model of the same brand/line. You will be good with that.

It's a 750 watt Coolmax CUL-750B. I got it for $10 from a friend. It's lasted me a year and a half so I'd say for $10, it was a really good deal. I'm just glad I got this thing to boot so I have something to do my work on. Thanks everyone for helping me troubleshoot through this.
