PC restarts on startup

[1two3]

Hi,
My pc was working fine intil 2 weeks ago when I suddenly started getting bluescreens occasionaly. But today, after I got a blue screen saying Kernel stacked inpage error, the pc just reboots right before the windows loading screen.
specs: Radeon 1950x, Intel core 2 quad, 2 x 1Gb ram, Asrock 4coredual-sata2, and 600w psu.
I can provide more details if nessesary.

Will need the exact error code and message. Have you tried to get into Safe Mode or try a repair install? How about last known good configuration?

How are your temps? It is hot and humid out now PC's are getting really hot.
