PC hanging up.

Hello,

Recently I started experiencing some difficulties with my PC.
For some reason, while playing CS, I get a hardware hang up. The video suddenly stops, sound jitters for a few seconds and also stops, and the keyboard stops responding (even the caps lock light does not switch while pressing).
Also from time to time I have problems restarting the PC when this described problem occurs. I press the reset button, I can hear the HDD turning back on, but there is no video signal to my monitor, tried reseting a couple of times, still the same. Then I shut down the PC while holding the "Turn on" button for a few secs, wait a couple of minutes and the PC seems to be fine.  I have a guess that this might be my VGA problem.
I have opened the PC, tried cleaning the dust, this did not help. I also had an idea that this might be because overheating so I attached an extra cooler to my VGA, and also left the hood of the PC opened. It really gets all the cool air it needs. Please give some directions which part of my CPU it could be.
I also have a hunch that this could be caused by the power block, because the cooler of the power block seems not to be working. Also my PC is on 24/7 and at the moment it's cool. The VGA seems to be hot I might say. It is on the edge of the state when its too hot to keep your hand on the radiator.

Also from time to time when my computer goes to "screen turn off" mode, when I try to bring the windows back on , all I see is my wallpaper and my mouse. The mouse is responding normally, but I do not see the login screen. I tried all different combinations which still should work while not logged on, like ctrl+alt+del, some times they work and some times they don't. This might be a software problem so if this has nothing to do with the first problem, do not pay attention to it.

Hello Jammer1224,

There are a few things to try.

Get hold of a Desktop fan and point it at the innards of your open case. Does this help with the lockups?

Remove your VGA card and reseat it. It isn't unknown for a card to become a little loose due to expansion and contraction and reseating can help.

Have you upgraded video drivers lately?

Regards,

Robmonster

If the PSU fan is not spinning, then the PSU is overheated and probably damaged. Replace it.

The PSU seems to be ok. I have noticed that it works right now. I haven't updated the video drivers, but I am sure that this is a hardware malfunction. I've tried reseating the VGA. The case is open and I am sure that it gets all the cool air it needs.

Highfive Gives IT Their Time Back

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

A problem that only starts to occur under heavy 3D gaming and goes away after several minutes of waiting sounds like an overheating problem to me.  If the radiator is too hot to keep your hand on, that means it is operating beyond normal ranges.  Install a case fan and aim the air over the radiator - it should dramatically improve the cooling.

Extra coolers on the video card don't help unless they are pulling the heat off the hottest components.  They should be placed over the graphics chipset and the video RAM for best results.

It's not only about cooling the various parts of your PC, neither it's about spinning the fan of the PSU; it may be also about wattage power of your PSU. A VGA such as the one you're using needs higher wattage PSU, at least 450 w.

Good Luck

Sorry I was away. Since my computer has been sent to a repair shop. They said that the problem is in the mother board but its because it got blown off by the PSU.
