I have a dell e510 its about 5 years old and recently it started shuting down and starting back up again, it seems to be more frequent lately to the point where its not even letting me log on, I changed the power supply and cleaned it out but no luck.

if your warranty go to the supplier computer . However you can use the software diagnostic coming with the computer and test it for to see if a problem a software or hardware.

God bless you

It seems that your system memory is the cause of problem
You can run a diagnostic check on the system memory.
If you have two memory sticks in the system try to run the system with one memory stick installed at a time, This will give us a proper idea of which memory stick is causing the problem.

How old is the fridge? Newer units will run more frequently and make "running" noises.

Is one of the options to disable auto restart on error? If so, choose that one and you'll be able to see what error is preventing you from starting. Post it back here so we might help.

If your laptop is more than 5 years old with all the new technology thats come along lately it's probably time to replace your old work horse. The cost of repairing an old laptop can be more than the cost of a new one.

I also have this same problem, which seems to be occurring more and more lately. Any solutions?

well it looks like starter is going bad or the battery is bad if not that try checking fuel filter history and or fuel injections

Sounds like a bad mobo. 8 years! Damn let it die already LOL..!!!

I had this same problem with my Arcam AVR300. I ended up shipping mine to an Arcam repair center and they repaired it and shipped it back for under $200. The problems were cracked connection on the start relay and they replaced power supply diodes. Very well worth it and now I can enjoy it again!

Try a system restore. If that doesn't work download and revert back to the old bios.
