all has been working well until today,i bought an acer 19 inch monitor and an xsonic(some generic brand im guessin) keyboard and a generic optical mouse. after installing these everything worked fine for about 4 hours when the computer just randomly shut down, so i restarted it and logged in again.. about 1 min later it shut down, i repeated this process 3 times, then was able to run adaware and spybot, however it shut down about 5 mins after finishing scanning. Im not sure what the problem was .. so plz help

I just installed Win98SE on a machine, with a new HDD, and previously had Win ME on the machine (and old HDD). Now I get the machine up and running, but it shuts down intermittantly. Just out of the blue.

Let me know if you found out anything as to the cause.

Thanks.
