I was using this computer for the last 4 years purely as a media centre. Something has gone amiss somewhere, as a while ago it has decided to boot up fine and then freeze mid-operation. It seems to do this regularly until it's cooled down. Then as soon as it heats up it will freeze again.

After this happened it gave me an excuse to build myself a high spec home theatre PC. So I have absolutely no use for this now. It may be an easy fix, i.e. may need thermal paste re-applying etc...  but I am no computer expert when it comes to diagnosing faults. Hence being sold as spares or repairs.

Please note that the hard drive is NOT included, as this has data on and I need to format it, but can't due to it freezing up. Comes with mains power cable, but no keyboard or mouse included. In good condition other than the fault and missing hard drive.

I'm looking to just get it out of the way, so £25 takes it o.n.o.  I would prefer collection (from Wrexham, North East Wales), but would be willing to post if cost is covered.
