Sometimes it crashes when the PC isn't running a game. It crashed when I was playing GTA V and when I rebooted, it crashed to black again. I wonder if the PSU is failing.

Update: Memtest86 ran and said there were no RAM errors

1. yes 2. Within the last 2 weeks 3. Last recorded temperature was 60.1 C 4. Not yet 5. No 6. Yes, MSI GTX 970 NB: I was playing GTA V to measure the temp of CPU at crash when I alt-tabbed, causing my PC to crash. Curiously, the screen didn't lock up, it just froze

Whenever I play games like GTA V, Battlebit, or GMod, my PC monitor will cut to black after a while. Like, no BSoD even. My LEDs will freeze up. I vacuumed out the dust from my PC, and it still crashed, albeit it took a longer amount of time to crash. GPU temp at crash was around 70 C. I have the latest GPU drivers. What could be causing this?

Yes, I fixed it

When I try to access my BIOS, it doesn't display anything. My monitor just goes black when my BIOS loads. It says DISPLAYPORT NO SIGNAL, then goes black like it is about to load, but it doesn't. It just goes right back to DISPLAYPORT NO SIGNAL. My DisplayPort cable is connected to my GPU. I tried connecting an HDMI cable from my Mobo to my monitor, to no avail.
