My pc (win7 x64) randomly freezes (nothing responds only solution is a hard reboot) usually once a day sometimes it goes for 5 days with no freeze.

Steps I've taken so far:

  • Updated all drivers from their official websites
  • Memtested RAM
  • Monitored temperatures/fan speed to see if theres any correlation to the freeze (all within norm)
  • Re-slotted components in case of bad contacts
  • Looked trough event viewer for potential causes
  • Tried to look for patterns in what I do before the freeze occurs so far seems pretty random
  • There is no minidump file as the pc doesn't BSOD

What are possible causes for full freeze (caps lock led doesn't work for example)?
Am I correct in assuming a bad driver would cause a BSOD instead?

I suspect a faulty piece of hardware likely motherboard/psu but I have no idea how to find out for sure.

Any ideas?

  • Possible hard disk failure. Check your hard drives for SMART errors [How can I read my hard drive's SMART status in Windows 7?](http://superuser.com/q/29240), and [What is the easiest method of checking SMART status for your hard drive?](http://superuser.com/q/14803) – DavidPostill Mar 27 '16 at 11:02
  • Did so, no errors reported – Jin Mar 27 '16 at 12:46
  • USB 3.0, no, no, no. Also stress/stability tested CPU with prime95 and GPU with furmark no freezes. – Jin Mar 28 '16 at 03:07
  • Ok deleted that, missed the part about this being a total lock-up requiring hard shutdown. What is the motherboard & processor? And all the rest of the specs of the hardware. Do you use a UPS? – Psycogeek Mar 28 '16 at 20:00
