Computer stops responding

June 28, 2009 at 12:29:59
Specs: Windows XP
I have a problem where my PC stops responding in games or windows. If I press the mouse button a couple of times the computer then beeps, my cursor hangs for a couple of seconds. Then the cursor will move before halting and the PC beeping again.

This happened once when i was playing a video, the video + sound continued on fine. If this happens in a game, the whole game hangs.

I have the latest drivers + bios + windows upates for my machine. The temperature in windows is also fine and does not seem heat related.

CPU 2.99Ghz Core 2 Duo
4Gb Kingston
275 geforce Novatech own brand
750watt power supply and some other gubbins.

canispeaktodave, my SWAG, memory. Since all seems fine for a period of time and THEN it acts up, sounds like some memory filling up.
Emptied 'temp' files lately? They're usually deleted at shutdown.'Always on' machines need to be rebooted now and then to let Windows 'clear it's head'.
How about 'index.dat'? A common ailment is a file called 'index.dat'. It gets read every time and can take quite a while if it’s too bloated. It's like a log file and keeps a record of every site you visit on the web. Empty, it's 32K, but it can grow HUGE. It's a protected file and can't be deleted by normal methods. CCleaner (free @: can get rid of it (not to worry, it gets rebuilt EMPTY on the next boot.). All this falls under the heading of 'routine maintenance'.

Unfortunatly I do not believe that to be the case, thanks for the reply. It's a recent build. 250gb bootdrive and a 500gb storage drive, both with plenty of space.

What I do not understand is it seems unrelated to heat/cpu intensity etc. The only difference is when it happens in a game the game crashes and needs a reboot. If it happens when using the net it can recover if I leave the computer alone for 5 minutes.

Here is the events that unfold:

1. Computer hangs, in game or just windows.
2. The mouse cursor can still move
3. If I click the mouse button roughly 6 times, the computer beeps and then the mouse stops.
4. 3 seconds later another beep, and the mouse cursor has moved to where it should have moved to before it beeped.
5. Repeat number 4 until unhangs

It's almost like it is a problem with the message queue that gets filled up with commands and it's one in one out, a bit like if you queue up too many key presses in dos.

Any ideas?

canispeaktodave, still sounds like a memory thing to me.
HD size isn't the issue, it can have massive space available and make little difference. RAM memory is what matters.
To play games, watch videos, etc. I'd like to have at least 1 gig. Anything less seems apt to trigger buffering and cause what you describe.
The whole idea behind the scan, shutdown, etc. is to scrub your RAM and make sure you don't have extras claiming any of it. HOW MUCH RAM DO YOU HAVE INSTALLED?

I have had similar issues on computer before where the power saver mode was the cause. I don't know how other people feel about this, but often times the first thing I do when I complete a fresh install/build of a computer it to completely disable this feature.

Some software and hardware simply do not function well with it.

Sorry Ed in Texas, are you selling that cleaning software? I'm not sure if it is a form post as i mentioned how much ram i had in the first post. I'm very sure it isn't a problem with the ram "filling" up, windows does a very good job with memory management and utilities like you suggested do free memory but move it into the page file causing slower access to the memory that has been moved. Thanks for your response however.

Shannonk, i'll have a go at that thanks. if i turn off power management in the bios the computer wont start up. Are you talking about windows power management?
