I upgraded my 1150 Cpu from a 2.6 celeron to a 3.2 P4 mobile cpu.
the machine booted fine and worked fine for some time.
though after a while it shut down due to a over heat and now when i boot the screen is blank,
the fan comes on , the hard drive starts and shuts down then the fan stops.
i reinstalled the 2.6 and everything is as it was before the upgrade.
i know this 3.2 should work because through research i found that others have used a 2.8 P/N SL725 with no problems
and the 3.2 P/N SL77R both have the same specs.
I am at a loss any guidance would be great.

If it shut down due to overheating, it could be that the excess heat in the case fried the GPU. Have you tried connecting it to an external monitor to see if that works?
