PC Help - 8 months old

Hi, Im new to the forums, I would class myself as advanced, but Im hoping you guys would know whats wrong this time?

I have just put my room back to normal, am a radio ham, only alteration this week is an old valve radio sitting on my desk between the tower and the monitor!!! :frowning:

Firstly the pc became very slow and started to be choppy, after two re formats things seem a little better, the wireless internet from BT keeps dropping out, the pc and applications seem a lot slower, and now the dvd drive has stopped see the links for what ive found so fat

ATAPI DVD A DH16A1L not reading blank dvd’s - FixYa

Now the dvd rw drive dont work, do you rekon its a virus?, the valve radio? the heat or the full moon???

Thanks Lawrie x

What’s the specs of this system?
