I tried to overclock my AMD X4 845 just for the hell of it which ended up being the worst mistake I made. After overclocking from 3.5 to 3.8 my computer wouldn't boot so I read that resetting the bios by using the jumpers would fix it. I held a screw driver on the pins for about 5 seconds but the computer was plugged in which I think messed everything up. I tried to take the cmos battery out for 10 minutes, unplugging, resetting to optimal settings, and everything I could think of. I also tried to restore my PC to a previous date. Nothing works and I get the starting windows screen that freezes and then goes into a blue screen for a split second which then starts the whole process all over again.

My specs (if it even matters...)

AMD X4 845
8gb Hyperfury X ddr3
Gigabyte GA-F2A88XM-D3HP
Gtx 1050ti
Seagate 1tb HDD
450w PSU
Windows 7 Professional 64 bit

Since I don't think you reset the BIOS correctly, do the following. unplug your PC and remove the side panel. Remove the CMOS battery from the motherboard and with the pc unplugged hold in your PC power button on your case, this will drain all your capacitors from the PSU and motherboard, after doing this the CMOS memory will lose power and reset since there is no battery inside then replace the battery plug the PC back in and try to boot again. This will reset the BIOS, if this doesn't fix it you may be looking at a bigger issue like a dead CPU. Also when you overclocked did you change the CPU core voltage at all?

Sorry I accidentally downvoted you trying to reply and I did change it in the bios but I never saved those changes before booting back up. I think it might be a corrupt file though since I put in my A4 5300 and it was doing the same exact thing...

Well, the A4 5300 Isn't overclockable, so I would remove it if it's trying to apply those settings to it. Are you certain you didn't save those settings? If it did save and the voltages were too high you could have fried the CPU.

I know, just wanted to test if it would do the same with another cpu, and its showing 3.5 ghz for the x4 still. i reset it to defaults for voltage and everything in the BIOS. i also swapped my hard drive to an old 40 gb i had laying around that has windows 7 installed on it and its still going through the same process of showing the gigabyte logo screen with the f key options and then it says "starting windows" and then restarts. im positive i never saved any voltage changes. i did save that overclock though which started this entire thing that i immediately reverted back to default.

I tried that through the dvi port on the board and i even swapped out my 1050 for my gt 710 to test that out and they all did the same.

I don't think that Athlon has video output capabilities so you may want to swap in that A4 and try the outs again. Otherwise I think you may have fried something, my first guess would be the motherboard since you already tried the CPU, I would take it to a computer shop and have that board tested along with your GPU PSU and Drives to make sure nothing else was corrupted or broken.

I fixed it by just reinstalling all my drivers and the OS from the CD I did eventually find. I made sure I backed everything up and checked my hardware this time lol (all of which is detected and functioning properly).
