Computer freezes/crashes exactly one hour after boot up?

[richjamacian]

The past few weeks, my main desktop (custom build) has been freezing and crashing an hour after boot. If I decide to reboot, I'll get an "NTLDR is missing" error. I'll power off the computer and wait a couple of hours and it'll boot normally. Otherwise I'll just power off holding the power button and the computer will boot like normal.

I've been trying to see what the problem might be. Temperatures are always fine. Memtest came back fine. I bought a PSU Tester (http://www.newegg.com/Product/Produc...82E16899261023), wondering if something was wrong with my power supply. The only thing that would happen is that if the tester was being held a certain way, the +5vSB would read as faulty, but be fine when the tester was readjusted. That might have something to do with it but I'm not sure.

I haven't tried running the computer in Safe Mode yet, and all virus scans come up clean. It's just really weird because it happens exactly an hour after booting up (+/- 1 minute).

Some specs just in case y'all need it:
AMD FX 8150 (previously OC'd to 4.2GHz, but now running at stock clock)
Corsair GS800 PSU
HIS Radeon HD5850 (Rocking it old school)
HyperX 2x4GB
Crucial 64GB SSD (for OS and programs)
WD 1TB data drive (for data)
Samsumg 1TB data drive (for data)

Crucial M4 known firmware bug. Update your firmware, then you should be good.

Yup, as soon as I read the thread title, I thought "SSD bug".

I had the M4 bug myself. Easy peasy.

I figured it was the SSD, but because my BIOS is UEFI, I couldn't use the windows tool and I didn't know you could manually install using the ISO lol. But, I finally got it working and everything seems to be working as planned. Thanks all :awe:
