pc froze and now running good after chkdsk

Then just leave it be and see what happens over the next 4-5 weeks. If the problem comes back, let us know. :)

It may be graphics card or memory related. There are no known problems with Firefox.


Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).



Download and install HWiNFO64 Download to check hardware temperatures.



Run Hardware - Stress Test With Prime95 to determine any hardware problems. Run each test for a few hours or until you get errors. Post back if you get errors.



Use FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net to test the graphics card GPU. Then use the |MG| Video Memory Stress Test 1.7.116 Download to test your graphics card memory.

i dont know if this would be any useful info but after my pc locked up i had to reboot and i got this message

this can be caused by unplugging a removeable storage device such as a usb

That message indicates that your hard disk has corrupted or damaged sectors again. Run Disk Check with both boxes checked, again. This is beginning to look like a failing drive, so backup any important data as soon as the disk check completes.

Good news is, idle temperatures look good.

If you end up replacing the hard disk, see if it improves stability.

Bad clusters means you had bad/damaged (physically damaged) sectors. This is a mechanical problem with the hard drive. Physically damaged sectors by itself does not mean the drive is failing; drives are actually designed for bad sectors and have spare sectors to replace them. However, if the head is running into sectors and clobbering them, damaged sectors will mount to a point where there are not enough spares to replace them. That is one way in which a hard drive may cease to work. That is why I said that if you continue to have hard disk related problems, you should consider the drive as failing. I would run disk check again and see if any more bad clusters are found.
