Memory Upgrade
Random Access Memory (RAM) wears out over time. If your PC frequently freezes, reboots, or brings up a BSOD (Blue Screen Of Death), bad RAM just might be the problem. Corrupt files can be another sign of bad RAM, especially when the corruption is found in files that you’ve used recently. Another possible symptom: The PC slows down considerably as you use it, but seems re-energized after a boot.
