So, my computer decided to fuck up.
It was after messing with the OS (Windows 8 FTW) - So I assumed unplugging hard drive and booting up some live cd would help. It didn't - Some splash screens and consoles loaded up, but never the full grafical OS - and I tried a few. Then I went to test my RAM with memtest and found out it was broken - so I sent it to the manufacturer, got my return. I tried to boot it (a live cd) with new (tested) RAM and no hard drive - same failure as before. If I boot it up with the drive, it doesn't even boot - it stops after Veryfing DMI pool data. Also it quite often says CMOS failure (but not everytime) so I bought a new battery - and it still does.
RAM - checked.
Hard drive - irrelevant.
I assume it's something with my mainboard(ABIT IN9) than. But I have no clue what could it be and how I can fix it. Any ideas? (I can post more info, just tell me what is necessary) Thanks in advance.
