as soon as i rebooted from the 10.5.5 update

the screen flickered with anomalies like this

http://trsrockin.com/images/m_encounter.jpg

i thought nothing of it well it just happened again 3 times in a row

one time it went into a kernel panic and as i rebooted while filling out the kernel panic report it did it again

this time it wouldn't boot it just gave beeps not sure how many its either 2 or 3

so what's the diagnosis guys?

Three beeps defective memory or defective memory slots.

Try reseating the modules very firmly.

If no joy remove one pair of whatever memory you have and boot again.

Next try booting from install DVD and run Repair Disk and then Apple Hardware Test, which also checks memory.

Still no luck beginning to look like a logic board, so maybe off to local Mac dealer.
