Hi all, just signed up here. I did ask this Q on the intro thread but after I read that no questions should be asked there! I had my Dimension 3000 in standby when we had a power-cut and next time I looked I had the flashing amber power light. After reading up on possible causes I disconnected everything, lifter the bonnet and popped the battery. Checked battery was OK and refitted then just connected the power lead. I noticed a single green flash (accompanied by a jolt of the fans) then the usual amber flashing light. Green light in m/b was on. So I just went round and re-fitted all power leads and gave everything a wiggle. I even lifted the RAM. Tried again - same. Put the RAM back and thought I'd try a different mains socket (why not?) but as I plugged the lead into the PC - BANG! Power lead 5A fuse is OK but no lights at all now...... Any idea if a fresh PS (HP-P2507FWP) will fix things? Many thanks guys.
