Sooo I messed up. I posted earlier about this board, and how I could only use the bottom pci-e slot. My solution was to switch motherboards with the one of my brother's pc, as his case doesn't hinder the bottom slot to be used. The board worked fine before with a 2600k, and I updated to the most recent bios After I inserted a 2500k, I got no post. So when I boot up, without even a graphic card nor display connected, one piece of ram (doesn't matter which slot), no sata drives, it goes in a loop, from 14 to 19 to 20. Sometimes I get 00, but one of the ram sticks I used might be bad. When I press clear cmos button on the back of the board, I get F3 (recovery image found). Tried ram that worked -before the switch. Before swapping the parts It gets stuck on 20, this happened often. Without ram I get error 14, static. Things I tried: clear cmos, taking the board out and looking for shorts, reseating the cpu, there are no bend pins on the mobo, trying different kinds of ram on all slots, putting the graphic card in all 3 slots. Power supply works fine. Only variable left is the cpu, but I'm not really inclined to open them up again, I have only so much thermal paste. Do you think I botched the board? Or maybe microcode error from the cpu? The cpu worked before the switch, and I took both out at the same time and put them directly in the motherboards. At this point I'm seriously considering buying a new mobo and ditching this horrible motherboard

Hello everyone, Not sure where I could of posted this so I posted it here. I have an AMD CPU & recently I noticed it's been a bit slow from time to time. I checked BIOS and Cool & Quiet is disabled, but CPU-Z is saying I get 1.4Ghz when I'm idling, Why won't it disable? I have reset BIOS to defaults, rebooted then re-disabled it and nothing. I have turned it on, rebooted, turned it off again etc. It never used to do this. Any ideas? Thanks

(Generated by PCPartPicker 2013-06-02 14:20 EST+1000) I've recently updated my system with a new PSU, Graphics Card and Ram. Everything else in this list was happily running until a few days ago when it randomly shut off. I assumed it was my old PSU as I'd had some trouble with it before and it was due for an upgrade anyway. I tested that the PSU was powering on the system (minus the graphics card) before installing it and everything appeared to be fine. I didn't actually test it with a monitor though. After installing everything in the case except for the graphics card I decided to boot up the system to remove my old drivers before installing the 7970. However, the system restarted after less than a second. Upon showing something on the monitor I was informed that there was a CPU over voltage error and was given the option to go to the bios to change my settings. I reset everything to defaults and tried again. This time the computer restarted roughly twelve times before I switched it off manually. I tried again only to be told that in addition to there being a CPU over voltage error that Surge Protection had been enabled to protect my motherboard from a faulty PSU. So far I've considered that either the CPU, motherboard, PSU or some combination of all of them is at fault and that I will have to return something or everything. What am I looking at here? Is everything dead or can I salvage something? Thank you for your help, I'm kind of freaking out here. I really appreciate any thoughts you may have, even if you're not 100% sure.

Hi, Abit NF7-S - Does anyone have one of these please? An electrolytic capacitor (C475 adjacent to Dimm Slot # 1) is missing on the Mobo that I'd like to use for on my test-bench and I'd like to replace this. Should anyone on here know what value and voltage rating this is meant to be I'd be most grateful to know. Thank you.

It seems that the Phenom II x2 555 can be unlocked to a Phenom II x4 B65 processor the vid: I have this set-up: Motherboard: Biostar A780L Processor: AMD Sempron 140 unlocked to Athlon II x2 440 Graphix Card: AMD Radeon HD 1GB 6750 RAM: 2GB DDR2 A generic 600W Power supply which I want to replace with a branded FSP Hexa 520W Here is what is shown in cpu-z based on my PC: http://s8.postimage.org/6u4ypgk91/Untitled.png Originally, I am planning to buy a Phenom II x4 955. But I found out that it has been phased out for almost a year now. All I have found so far are Athlon x2 dual cores. I can't believe it. Right now, I have a Sempron unlocked to Athlon II x2 440. So, I though that unlocking Phenom II x2 555 to Phenom II x4 B65 is possible for my mobo provided with the PSU. But I want to hear from you guys especially about safety measures. I am a newbie here but I am aware of the possible consequences that I can face after unlocking. The unlocking of Athlon II x2 440 came from just a video turorial. I hope you understand. If it's not really recommended to unlock it, will the Phenom II x2 555 alone will suffice for playing AC3? I am also staggering for the low fps issue.
