Many problems

[nickginminden]

ok here is the whole story...

I have a HP a1412n.

It doesnt work.

It started having problems turning on a month ago. I took it to staples and had a new power supply installed.  worked fine.  now when i push the power button somtimes it comes on somtimes it comes on then turns right off.  I opened it up and looked for anything obvious. nothing.  so i tried to do system recovery. it goes through system recovery then goes to a blue screen:

if i dont select system recovery it goes to the safestart/regular start screen. ive tried all the options and it just comes back to the same screen.

ive run F1 (setup) reset all defaults...nothing

i tried to boot using the xp cd it gets to the part where it says to insert the cd and press enter. i do. then it says cd not reconised

also if i start it in safe mode it shows a black screen with a bunch of lines saying stuff about the drivers

other blue screen

Hi, let's try to address why the computer sometimes turns off during a boot.

Can you check the motherboard for any bad capacitor's. (leaking or deformed)

Check that all connector's are connected correctly.

Re-seat the memory.

Make sure to pull the power plug from the back of the case before you start.
