First off, thanks for your reply MicroBell.
Now with installing new OS I have 3 harddrives that I have tried in the system. Each one has different OS, win2000pro, winXPpro and win98se...
The WinXP is a fresh install and a New WD harddrive. this belongs with the system.
I've attatched a picture (hopefully you can see clearly enough)
that points to 3 suspect capasitors on the board..
maybe this is the problem....
But I will see what I can do about trying a new PSU. would you recommend getting a 300W or higher PSU. The one thats in there at the moment is only 250W ( could this be a prob aswell )
