I have a Dell Dimension 2400 with 2.4 Mhz and 40 gig HD that I bought about a year ago. This is the $499 machine they advertise, but with 256 RAM. It worked fine until about a month or so ago, now a couple of problems: Now often times when I am on the web, it locks up or 'freezes' on me, when I do a 'cntl-alt-del' and bring up the task manager, under the processes tab I find an item listed as svchost.exe that is hogging all or nearly all the cpu memory. Any ideas? The other problem is on startup of the pc, after the initial splash screen (which also shows F2 or F12), the screen then goes blank except for a blinking cursor at the top left corner. After 5 to 8 minutes the pc will go ahead and completly start up.???? I have just replaced the RAM with a new stick of Kinsington 512MB memory, no change at all.
