why does my pc restart on its own? it happens occasionally, sometimes when i put a diskette in the floppy drive or a cd in the cd-rom. SOMETIMES.

another prob i have is why do i have to shutdown twice before my pc turns off?

We need a lot more info...

Which version of Windows, complete specs (CPU, RAM, hard drives, etc), when it started doing thins (if it always has or just recently started), and whether you have installed anything new lately.

Possible causes:

-Everything not completely seated on the motherboard.
Reseat everything.

-Overheating
Check the system and CPU's temps either in BIOS or with temperature monitoring software.
If the system temp gets over 45 deg. C, then remove the computer's cover, and run an external fan. If this fixes things, then install additional case fans. Recommended locations are lower front and upper rear of the case.
If the CPU gets over 60 deg. C, then make sure there is thermal compound between it and the heat sink. If that's ok, then replace the compound with Arctic Silver3.
If no luck, then install a higher capacity heat sink fan.
If still no luck, then replace the heatsink with a more efficient unit.
Also, make sure the computer's fans are running, the vents are open, the computer is not
located in an enclosed space, and there is no internal dust build up.


-Overtaxed or bad power supply
Swap it out with a different(preferably higher wattage) unit.

-Bad memory
Remove and reinsert the memory a few times, try it in different slots, do not use any optimal settings for the memory in BIOS, and swap it out with known good memory.
Also, do not mix parity and non-parity memory.

-Bad video card.
Swap it out with a known good card.

-Bad MB.
Swap it out with a known good MB.

-IRQ conflict with a network card.
If no problems show up for the NIC in Device Manager, then remove it from DM, shut down, uninstall the card, and restart.

-Check for viruses and spyware.

-Uninstall kazaa.

Random restarts......if it's the same machine, it could be related to the virus problem you are facing in the other thread. (http://www.pcguide.com/vb/showthread.php?threadid=28140)

Yep, I agree, that needs to be resolved before anything else, it's probably causing all sorts of other headaches, and you can't tell until it's gone.
