Newly built computer freezing after first day.

Hi I have recently built a new computer for my brother, I didn't have much experience in it before but I talked to a few people and was informed that all the parts were fine.

ASUS P8Z77-V LX2 - ATX / Z77

ASUS GeForce GTX 660 Ti 2GB DirectCU II

Corsair PowerSupply (PSU) CX600 600W 80+ Bronze

Corsair Vengeance Low Profile 8GB DDR3 PC3-12800 1600MHz

Intel Core i5-3570K

Seagate Barracuda 1TB (Cache 64MB / 7200RPM / Sata 6Gb/s) ST1000DM003

After building in originally wouldn't show any VGA or HDMI signal, but after switching the slots the RAM was in it worked fine. The PC ran fine for the first night of usage.

Today it has been incredibly slow and when opening almost any program it will slow to a near stop then blue screening and restarting instantly without me even being able to look at the blue screen message.

Any help is greatly appreciated.

  1. Check memory settings in BIOS, make sure they are right.
  2. I have all of them set to auto, but as far as I can tell they are auto set at the right values anyway.
  3. Reseat memory modules then run memtest86 to see if you get any memory errors.
