Two days ago my computer started to freeze randomly, along with hard disk stopping. I tried updating the drivers, but it didn't help, so I checked hardware and found out that the power line was loosen. After I re-plugged it the hard disk didn't stop anymore then. But when I boot normally the computer BSODed with the error code 51. Everything is fine in safe mode though. So what seems to be the problem? Please help!
Hi skygate,
Error code 51 is a registry problem, it may be due to either the RAM or HDD.
Diagnostic Test
RAM TEST
Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 7 Forums
Note
MemTest86+ needs to be run for at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.
Make a photo of the result and post it.
Addition:
If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
If errors show up and you see them a lot later, no problem, the errors don't affect the test.
Diagnostics Test
HDD TEST
NotePlease run HDTune first, in the order posted!
- check the health,
