I'm not a genius building computers, obviously, I built two pcs in the past and just "finished" the third one. The first two pcs I've built are fast without any lag at all. I think the first pc I;ve built is a decade old. Works perfectly.
Now, I've put together a third pc and It's acting well... weird. It's slow, that blue halo by the cursor shows up, I get "Not Responding" messages, installing anything takes so long that I had to end it. Sometimes I cannot shut the pc down, it just won't let me. i also cannot install realteck audio for sound. Just a lot of problems.
All the parts were bought new. The CPU is an AMD FX-8320 Vishera and the motherboard is a MSI 990FXA Gaming. Actual assembling of the parts were done normally.
After putting the pc together, I let the computer idle when it's under the bios screen. The idle temps. are 20-22 Celsius. Motherboard temps are in the same range. Motherboard detected the 16GB (2x8GB) ram. First thing I did was updated the bios. Computer acted wierd with windows installed, not sure if I did something wrong so I reformatted the hdd and started again.
Windows didn't have driver's for wireless card, so I used the TPLink software no biggie. Installed Panda AntiVirus due to the fact it's lightweight. Firewall is Comodo. I have the same two software on another computer, that computer is fine. I don't think it's these two software causing the problem. No other security software is installed. OS is windows 7 professional 64bit.
Tried to install software for video card. It took about 15 mins and still not installed on HDD? PC froze. I have no idea what's going on. Sata cables are brand new as well. Could the ram be defected? I dunno, what should I do?
