Windows 7: System freezes and restarts randomly

System freezes and restarts randomly

I've been plagued by random restarts and freezes. After booting it's says "bootable device not found", than I restart system manually and everything is fine. This happens approximately every two weeks. In Event viewer I have a lot of errors and warnings. At time when system freezes and restarts in Event viewer writes "Critical".

It could mean that your hard drive is failing. You can use Speccy - Advanced System Information Tool To gather information about your pc and post it here.

That program will inform you who makes your hard drive, and then you can go to the manufacturers website and use their disk tool to see if its failing.

This scenario usually indicates a problem with the hardware. To help isolate the problem, check the following items:
1. Overclocking: Disable overclocking to see whether the issue occurs when the system is run at the correct speed.
2. Check the memory: Verify the memory by using a memory checker. Verify that each memory chip is the same speed and that it is configured correctly in the system.
3. Power supply: Make sure that the power supply has enough wattage to appropriately handle the installed devices. If you added memory, installed a newer processor, installed additional drives, or added external devices, such devices can require more energy than the current power supply can provide consistently.
4. Overheating: Check whether the system is overheating by examining the internal temperature of the hardware.
5. Defaults: Reset the system back to the system defaults to see whether the issues occur when the system is running in its default configuration.

1. Overclocking is is already disabled.
2. Checked with Windows Memory Diagnostics Tool and everything is fine.
3. Power supply is good. I didnt added anything. I have laptop.
4. Checked with Novabench and everything is fine.
5. Already did it several times.

I think that problem is in hard disk (I am not sure). When I used disk tool (from the manufacturers website) to see if its failing. My hard disk partitions has been disappeared for several minutes and than it comes back.

Dont know what to do next

You could also test the HD with Seagate Seatools and see what it reports.
SeaTools | Seagate

The report you attached also shows:
29GB SanDisk SSD i100 32GB (SSD)

Are you sure the SSD is ok?

Which alternative should I try: 1)S.M.A.R.T. check 2)Short drive test check 3)Short generic 4)Long generic 5)Advanced Tests

I tried Short drive test check and SSD fail

What should I do now?

I always start with Short tests because they run quicker.
Then do Long tests as they can take hours to run.
I don't think this tool works with SSDs, but I could be wrong.
Other utilities are needed for SSDs as far as I know.
Also the tests that do a Repair only work with Seagate and Maxtor HDs as far as I know.

SSD tools I've used are:
CrystalDiskInfo - Software - Crystal Dew World
Disk Benchmark | ATTO

I really don't know what is best to test SSDs ... perhaps others more knowledgable will reply.
Maybe SanDisk has a utility ?

Everything is fine.

How can I check if SanDisk has a utility ?
