Constant BSOD after fresh Windows install

[sotech]

Hello community, I'd like you to help with this annoying problem. I've recently formated and installed win 8.1 on my pc, but then i've got bsod's over and over again. I've tried uninstalling drivers and re-downloading them but there seems to be no solution.

I'm new to this, so if you may, guide may through what I should post and how to do it

Some specs:
AMD Athol II X3 445 Processor
4gb RAM
Amd Radeon HD 5800 Series

Thank you in advance

Without a Crash Dump I can't really say, based on the loose information I have I suspect that your Boot Manager was corrupted or damaged during the installation. You're not barking up the wrong tree assuming it's driver based, but if it's tied to your Boot Manager it won't matter if you're re-installing drivers. I would try running Startup Repair to see if you can repair the drivers tied to your Boot Manager.

The other thing is, it might be worth just re-installing the OS. You'll have to do that if Startup Repair fails.

If either the Startup Repair or reformatting work, I'd highly recommend you back up your data with a disk imager like Macrium Reflect or a snapshot tool like RollBack Rx.

If you want you can post the Crash Dump and I'll have a look.

I should've explained a little better. Well, first of all, I can boot normally, I can watch videos and use the machine without any kind of problems. But when I open a game, 15mins later, I get BSOD (first I got a IRQL LESS OR EQUAL. After a few hours, I got 2 KMODE EXCEPTION NOT HANDLED (i've managed to read their dumps, the only driver crashing was ntoskrnl.exe). Then I got a bsod white lines no readable text

Here's a list of things I did to check:
-Memtest: no problem, both rams, tested separately
-Windows memory diagnostic: no problem, same as above
-sfc /scannow: no problems found

What should I post or do now?
