Random pc crashes, not starting back up.

Hey, lately I have been having problems with my pc. Randomly my pc will freeze, everything stops responding apart from my task bar, if I start clicking icons on my task bar that eventually freezes too leading to a BSOD or until I just have to turn it off. Then while loading, sometimes it starts back up normally but most of the time it gets stuck on the boot menu and I have the occasional "Reboot and select proper boot device or insert boot media in selected boot device" or "A Disk Read Error Occured. Press CTRL+ALT+DEL to restart"

Here are my pc specs.

Intel i5-760 Core Quad Core 2.80GHz
ATI Radeon HD 5770 1024MB
ASRock H55M Pro Motherboard
4GB Ram
Windows 7 64bit

Anyone have an idea of what could be causing the problem?

More about random crashes starting back
  1. What is the brand and model, not just wattage, of your PSU?
    You could have a failing hard drive in general, or a corrupt swap file in particular; the issues when booting suggest the drive as a whole may have opted for early retirement. If you don't have them, make backups (if you can).
  2. The power supply is Right-Tec P4-650W
  3. +1 for failing hard drive. Goto device manager and find the model/manufacturer of the drive. download a diagnostic tool from the disk manufacturer and see if it says anything interesting. Win7 has build in backup to USB external drive. Programs like 'acronis true image' do a great job and have trial versions (and work well enough i actually bought a copy).

    Also, downlaod a USB bootable diagnostic (liek the one from cosair). See if that finds anything.

    good luck.
