I bought an Asus Z87 Sabertooth mb along with a Intel i5 CPU one week ago. Although I managed to install a new OS, the booting problems have been appeared from the very beginning. I was restarting 2-3 times before pc was going to booting stage but for last 2 days it's not booting at all. When I push the power button, motherboard gives random red lights every time. Some times it gives CPU led, sometimes VGA error. Can you please help on this issue?

Hi, test with another PSU like alexoiu suggested. Also make sure that all power connectors are properly connected, 8-pin CPU / 2x6-pin PCI-E (Graphics card) / 24-pin ATX etc. Clear the CMOS, and remember to reload the Optimized defaults in the bios after clearing the CMOS. See what happens when booting with only 1 memory module installed. Make sure the CPU Heatsink is properly installed to eliminate overheating issues.
I tried another psu but there is no improvement. I also tried booting with only 1 memory module installed, but same issues are on going I dont think PSU or the other hardware causing the booting issues cause in the first 2 days i was able to use my computer and i also managed to install and use Windows 8. But computer started to fail while booting gradually.
