I'm fixing an old Packard Bell Q6600 system that used to 'blue screen' having been given a punching attack by it's owner for not working (probably due to viruses and other malware).
The seemingly broken graphics card had been removed before the PC came to me. Apart from the missing graphics card the PC appears undamaged inside and out. Having installed a new CMOS battery and 'factory reset' the hard drive to make sure there are no viruses it seems to run fine running iplayer and other basic stuff.
Now I'm testing it with prime95. I'm getting a weird thing though. I've run it a couple of times, this time it has been running for an hour. Workers 1, 2 and 3 have completed about 20 tests, but worker 4 (CPU3) seems stuck on test 1. There are no error messages.
So, the plan is to sell this system, but I'm not sure in honesty if I should sell it as working with this issue which deosnt seem to affect anything else or if I should start doing things like taking out reseating the CPU and HSF.
Update: While I typed this, the worker 4 thread at just over an hour has completed test 1. Is this normal?
