For the last few days my comp has been acting rather oddly.
After a while, it simply freezes up. Sometimes quickly, sometimes slowly.
The effect is somewhat like it's running out of memory. Programs slow down and it grinds to a halt. The mouse still works though.
I've run a defrag and a virus check in Safe Mode, but it's still happening.
A restart and everything's fine again for about 30 mins, then it freezes again.
Hardware problem? It's as if it can't flush the RAM and locks up when there's no more memory available.
