PC Freezes Dear Tech Support, Once in a while my PC Monitor and Mouse operation freezes. I have Professional AVG 7.5 for the past three years. No virus shows up. Could it be a hardware problem? I have unplugged and re-plugged all peripherals and cleaned out the CPU and motherboard with a vacuum. What?s next? Much appreciation Mano.

I know this is an old post, but maybe it will help someone in the future. I own the same computer and had this exact problem with Kaspersky Internet Security. Turns out KIS 7 was detecting PS2.SYS as a keylogger. When I blocked the file from loading (per the software’s recommendation), I lost connectivity in both my mouse & keyboard. Eventually, I had to allow the file as an exclusion in order for things to work. Kaspersky says this is a known issue.

When the computer freezes is it just the mouse that freezes?  Can you navigate using the keyboard?  I would recommend running memtest 86, and prime 95, just to check your memory and processor respectively.  How frequent is the freezing?  Have you tried stopping a few of your larger processes?  Have you installed anything new recently?  Also I would try reseating your memory, and maybe having your power supply checked.  Doing these things will help limit it down some.

HP D9811 monitor freezes and then starts blinking on and off

Since you mentioned that your mouse freezes and your keyboard freezes, I'm pretty sure your problem does not exist in your monitor at all, but in the computer itself.

The first place I would look for a fix is in your video card. Since you started with a 98 machine and upgraded to XP, I'm not sure how that was done. It has been problematic in my experience to run a FAT32 file system under a XP operating system, and in those days it was a common upgrade.

The problem with it was, and is, that the drivers are built for an NTFS file system and FAT32 is on your pc.(maybe)

The first change I would make (well, as a tech, it would be to erase the hard disk and reinstall the os, but let's just talk about the fix here) is to look at the drivers for the video card, and check with the manufacturer of the video card for the most current one.

If that is already the most current, check the file structure to see if it is FAT32; and if so, consider backing up your data and reinstalling the OS under NTFS files structure.

good luck

My iBook G4 continues to run slowly and/or freeze

Try resetting the PRAM by turning on the iBook then holding option + command + P + R and wait till u hear another chime. If it still freezes, it may indicate an application may be causing it to lock up hold shift after you hear the chime to boot OS X into safe boot.

Laptop 'freezes' after about half an hour of operation

Is the hard drive making a clacking noise, and/or does the mouse freeze only once or freeze and unfreeze a few times before dying completely?
