Laptop shuts off after opening case to clean dust

Hi all,

I recently opened up my laptop case to clean out all the dust (it was overheating...) Now that I put it all back together, it shuts itself off (complete power crash) after a few minutes. The first thing I thought was that the RAM was corrupt, I bought new RAM, and upgraded it from 4 to 8gb. Weird thing is that the more RAM that is in it, the sooner it crashes. So, with 2gb of RAM, it will run and shut off after any attempt at the computer multitasking, with 4gb of RAM, the computer will turn on, but as soon as I try to open any software it crashes, if I put the full 8gb of RAM in, I can't even get to the logon screen.

My computer:
Toshiba A500
Intel i3
Windows 8
RAM (variable!)

Make sure you didn't unplug the CPU cooler, or get Everest or PCWizard and make sure the fan is spinning at all..

If you didn't inflict ESD damage (or any other damage), then it's probably a simple loose connection; perhaps a component needs reseated.

Scottiemedic: I can actually hear the fan spinning - I'm 100% sure it's not shutting down because of overheating - it shuts down way to quick for that.
ProStar - I'll try going through it again making sure everything it seated right and plugged in tight ... Is there any way to test for esd damage? Problem with a laptop is I can't swap out components to see if they are damaged ...

Well you sort of can, they're just not as easy to acquire as desktop components. There's really no simple way to test for ESD damage though as far as I know. It can rear it's head as mild, intermittent idiosyncrasies, or full on unresponsiveness from the hardware.

Have you run memtest+ on the RAM? I know, 'but it's new'. I have a 2x4gb set of Patriot that has an RMA on it on my desk, and it was new. Test one DIMM, one slot at a time (new stuff then old stuff). Maybe some junk is trapped in the RAM seat?
