Dell Dimension E510 Startup problems * need help Troubleshooting *

Ok, so the basic diskette seek failure problem is fixed however now, I have a looping screen set.

it powers on, it reaches the Screen for start normally , safe mode , safe mode w/ networking and such. I select start normally,  gose into splash and continues to loop those two screens. only.   now I have a Dimention E300 something and swaped the HDD's and they both boot...kinda I'm currently reinstalling windows on the one.

When I booted the E510  I did have a series of simi long beeps of like 3 second beeps like 6 of them before I removed my ram and tried reseating those. that fixed the beeping issue.

any idea's gang?
