Detailed Memory Test can be performed during bootup to prevent PC from even booting up if there is a memory fault. There are free programs on the web to run detailed memory tests. You can use these to verify. However, one simple method to verify is to put a small fan on the air vent of the Dell and check whether your PC still has the symptoms. If it does, then the problem is not CPU heating up.

Insert the XP disk into the computer.

Restart the computer.

Press any key when prompted to boot from the disk.

Press "Enter" at the first screen and "F8" at the license terms.

Highlight the drive containing XP and press "R," repairing the operating system boot files and removing the log-on loop.

The glitch logs you in and then logs you off the account.

This problem is usually caused by one of the programs that load during the computer's start-up.

Fixing this issue is a matter of ensuring that whatever program is causing the problem doesn't start up as soon as you start your computer.

The dial-up modem would install inside the computer in a PCI slot. VERY easy to install but a couple considerations before doing so... There are different sizes depending on whether the OptiPlex is a mini-tower or small form factor case. Also - you would need drivers for the modem that are compatible with the operating system you have installed on the computer.

This problem occurs due to various reason: too many software on your startup or your C: drive is full or may be because of virus. You can do a couple of things: 1. try freeing up your C: drive space, delete unnecessary things and leave at least 15% of space free. 2. Defragment your C: drive, Go to start and write Disk Difragment and press enter. Select C: drive to defragment it (do #1 first) 3. Turn off startup program. Go to start and write 'msconfig', a window will appear, click startup tab where you will find list of software name, untick the software you don't need then apply to restart.( Caution: This step is not recommanded for someone who knows what they are doing).
