First of all, this is not a new problem, but one that I experienced consistently since I installed w7 x64 on my new barebones laptop in 2010. My other laptop is sent for repair so I thought I might revisit this laptop which has been in storage.
The problem is, the laptop will suddenly freeze when in use (especially under high load), sometimes pre-shadowed by the hard disk light turning solid and the PC lagging significantly. The end result would be long pressing the power button to turn it off before turning it on again.
The diagnostics I have performed up to today are
1. chkdsk on C: and D: partition - No issues found
2.Hd Sentinel health check - Very healthy disk, 98%, 2 non repairable bad sectors. Approximately 5000 hrs in use, 50 failures, which seems reasonable upon consulting other forums.
3. Memtest86 - A total of 5 tests for each combination of ram units and slots. 4 passes for each test, 0 errors.
4.Clean and replace CPU and GPU thermal paste - No noticeable difference
5. Format and reinstall Windows - Problem comes back after a while
After doing all the above tests, I am still unable to identify the source of the problem.
At this moment I suspect three things:
1. The laptop is not made for 64 bit Windows that is currently installed, so I should downgrade.
2. The power supply is faulty
3. The hard disk is indeed faulty despite favourable diagnostic results.
This problem had made my $1300 investment into a paperweight sitting in my storage. If I can in anyway make it a reliable machine for even light web browsing, I would be ecstatic.
Will appreciate any tips and guides, thanks guys.
