Hey guys, so I've been sorting through other solutions here and haven't found anything that's helped me so far.

Updated my processor to the AMD A10 7870K APU a few months ago and have had nothing but trouble with it. Constant blue screens and it's really slow, even to start up. I've tried everything, all drivers are up to date.

My specs are:
A10 7870k processor
Asus A55BMA/USB3 mobo
2x4gb RAM
1tb HDD
Windows 7 64bit

I'm not using a standalone graphics card at the moment which I thought might be my problem, but my previous processor was the A6 and that ran without any problems using the integrated graphics. Any questions just ask, I might have left out something important!

That a great mobo, go for it. If you want something cheaper then buy this https://www.amazon.com/ASUS-Micro-DDR3-Motherboard-A88XM/dp/B00KCLIFUE/ref=pd_lpo_147_tr_t_3?ie=UTF8&psc=1&refRID=B19MYFNDQQ8FCGZ88Z13

I would say that you firstly but the mobo and then the PSU. Although PSU also can be the cause but I'm sure about it so you are better upgrading the mobo first.

First of all A55 chipset can't work with that processor properly. For A8-A10 series you need to have at least A68 series mobo. You have an unlocked A10 series APU so you should buy an A88 chipset motherboard or A78. Yes, it's mentioned on ASUS's website that it supports the 7870K but to utilize full potential of that APU you need a better chipset.

Can't find a model or make on the power supply, just its general info so I think you're right about needing a better one. Should I be aiming around 750w with a branded power supply? And if so is there any you would recommend in particular, especially if I'm going to add a GPU to my system in the next couple of months?

And thank you darthvader30 for that info, I've definitely considered it already, I'm going to look into an upgrade!

I'm not an expert on power supplies, someone else would be better suited to answer that question for you, but you don't need anywhere near 750w. Your system in total probably draws less than 150w under torture testing, there's just a good chance that your power supply isn't delivering good, clean power.

As darthvader30 suggests, it could be your motherboard, but I'm skeptical Asus would list your CPU as supported.

If you can, then go for Corsair RM550x. It's a great PSU, fully modular, 80 plus gold certified and has great ripple suppression. If you want a cheaper PSU then get Corsair CX550M. You can't go wrong with either one of them but the RM550x is better if you plan to overclock.

Thanks for the help guys, going to invest in a new power supply first, probably the cx550m and if I have to go the mobo route I'll be going for the Asus A88X Pro or Gamer, which would you recommend darthvader30?

Just want to add one little thing from experience, if you find the problem continues even with the other changes then check your RAM. I was having horrible problems with an APU and discovered if I disabled its XMP profile and manually set it up the memory then the blue screen issues vanished. I did a lengthy Prime95 torture test with no errors when before it was halting after a few minutes.
