Hi, my brother's PC has been freezing up over an year now and I'm getting tired of it, so I'm writing this to see if I can get some help. So, every time I try to play a game or watch a video on Youtube, my PC freezes up and I can't do anything, not even move the mouse. The only thing I can do is restart with the restart button. It gets frozen up if I have opened for example Skype and Winamp at a time... Specs: 1.7Ghz AMD Athlon XP 64MB Nvidia GeForce MX 440 512MB RAM 80GB Hard Disk This PC is quite old..around 5 years.. I changed the Processor to the one I have (1.7Ghz AMD Athlon XP) and the Hard Disk too (80GB Hard Disk). I changed the processor because the one i had before overheated and it..blew up and the hard disk blew up too :D (After i changed them i have this problem with the freezing up) I think my problem is from the hardware since I tried reinstalling WinXP and i Formatted the Hard Disk too..

imapi, SWAG, my guess is memory. When there's not enough, buffering is triggered. While that's going on, things come to a screeching halt and it may seem like the machine locks when in reality, it's quite busy. If you wait long enough, does it come back? Seems to me you're trying to do a LOT at once. HTH. Ed in Texas.

I tried waiting for about 30 mins but it doesnt come back...its not too much things its normal to have open 2 programs...to watch a video on Youtube i have to terminate much processes from the Task Manager. Before I changed the CPU and Hard disk it didn't freeze up and I had open more than 2 programs at once.. Guitar Hero 3 roxor

There may be several reasons why your computer may be freezing. First question is when was the last time you cleaned your registry. Having a corrupted registry can cause a whole host of errors and problems. Freezing up is one of them. If you have a lot of unnecessary registry keys that are hogging up your computer resources. Your computer is bound to choke. Scan your registry with a good registry cleaner. If you pull up more than 20 errors or duplication, clean your registry. 2. Depending on your RAM specs and your computer usage. This could also be a the issue. Having an insufficient amount of free space does not allow your RAM to function properly. If you are using a lot of RAM by net surfing or other activities without enough empty space your will get freezes. You don't need to buy new RAM but you should increase your free space by removing unnecessary data and perhaps increasing your virtual memory. The below link will show you how. 3. Spyware could be the culprit, so do a scan and see if your computer is infected. 4. Another area is a hardware drivers. This could be the problem if new hardware has been added to the system. So, the drivers should still be up to date. So try the first two suggestion and see if you can get your computer to stop freezing. Check your drivers. 5. Lastly, check the dust buildup on the fan to make sure you system is cooling properly http://www.delete-computer-history.... none

1 - I tried this with Regcure, it found some errors but it's still freezing up. 2 - I freed up ALOT of space on my hard drive but still freezing up. 3 - Tried scanning with Norton Antivirus and after that with NOD32 but still freezing up. 4 - Tried with the program Driver Scanner (Uniblue) but its still freezing up. 5 - Cleaned the dust built up but still freezing up. :( Guitar Hero 3 roxor

Check out the resource manager. 1. Press CTRL-ALT-DELETE 2. Click the Resource Monitor in Task Manager 2. Click the tabs under Disk, Memory, CPU and Memory. 4. Search for any irregularities, spikes or interruptions. You may have bad sectors on the hard drive that causing the computer to freeze when trying to skip or read the bad sectors. none
