Question about Dell Inspiron 530 Desktop Computer

1 Answer

Not able to access programs or shutoff correctly

This happens only when the computer has been on for a number of hours. When I try to open most programs, a red sign comes on saying I do not have "correct permissions." Then when I try to reboot or to shut off, the computer gets stuck in one of the phases, and I have to push and hold the start button to force a shutoff. When I turn it on again (even if immediately), a screen says the computer didn't shut down normally. But then I tell it to "open windows normally" and it does, and everything is fine..all programs work, shutoff works, no problems....for a few hours.
This happens every day, even when the programs which I have been using during the day are different from those of the preceding day. Help.

Have you opened the computer case and cleaned out all of the dirt and lent lately? The way you discribe it happening after a period of time leads me to think the CPU is overheating .

Tip

Flashing BIOS via software




If you have access to the computer when it's turned on, you could try one of those programs that remove the password from the BIOS, by invalidating its memory.
However, it might happen you don't have one of those programs when you have access to the computer, so you'd better learn how to do manually what they do. You can reset the BIOS to its default values using the MS-DOS tool DEBUG (type DEBUG at the command prompt. You'd better do it in pure MS-DOS mode, not from a MS-DOS shell window in Windows). Once you are in the debug environment enter the following commands:
AMI/AWARD BIOS
O 70 17
O 71 17
Q
PHOENIX BIOS
O 70 FF
O 71 17
Q
GENERIC
Invalidates CMOS RAM.
Should work on all AT motherboards
(XT motherboards don't have CMOS)
O 70 2E
O 71 FF
Q
Note that the first letter is a "O" not the number "0". The numbers which follow are two bytes in hex format.

Assuming that you are correct about being malware free, my next best guess is that the machine is overheating. Overheating can cause a PC to slow down. A simple way to help with an overheating PC is to clean all dust from it, especially dust stuck in the fans and on the CPU heatsink.

Desktop keeps rebooting, not the system, just the desktop


Hi
Sorry to hear about this happening. What was the last true function that your computer done that was "correct"?

From run type
cmd,
restore option from Start; all programs; asscessories; system restore.



From run, type msconfig will show you the programs you are running. might be able to locate the file you mention above.
hope it helps

Loopback IP


I don't think the loopback IP can be disabled. Some suggestions: Try looking in the Registry for the Windows Media Encoder settings. (uninstalling doesn't necessarily delete the registry settings) Make sure the program is running with the correct permissions (Run-As Administrator, for instance). Check your Windows firewall (or other security programs you have) to make sure it's not preventing it from working properly.
