Ok first let me say, Wow, wasnt expecting these kind offers. Now we have some good news.
Good news, after much looking over things, i havent lost as much as i originally thought, what ive lost i.e blown is as follows
1 HD4890 1gb card - still have 1 left from crossfire
2 sticks of memory
1 HDD - thankfully not the one with IL-2 on it lol
And obviously the damned blasted stupid thing PSU!!!!!!!
Ive got no idea how ive got away with just those losses, at the moment this computer with the remaining bits working are running off a 350W PSU, which quite frankly is crap and old and i dont want to stress it and risk losing more.
slight bad news, ive gotta wait for a replacement PSU and ill be up and running again, albeit a bit underpowered from what im used to, but at least ill be back. new PSU should be with me by monday or tuesday.
So thanks for the offers guys, but as you can see, it would appear ive been slightly lucky that 50% of the computer survived.
