monitor losing signal

randomly (normaly when gaming) the screen losses signal and the pc becomes unresonsive (power botten dosnt work 2 turn off). i have tryed it on vista and still the same problem i have tried many diffrent drivers and still no fix.

 

Hi and welcome to the BBS,

I would investigate if there were temperature problems. Has dust been cleaned out of the case? Run with the case open and check that all the fans are spinning freely and particularly the fan on the graphics if it has one and seems to be related to graphics intensive programs like games. Consider that there may not be enough movement of air through the case and if extra fans may be required.

You can try reducing the resolution of the graphics if you are running at/near maximum for your graphics system. For games, it will be in the Options menu. Alternatively, you could probably turn off any "extras" like shaders, shadows, etc. (It should have information in the manual or Readme file, look in the game's folder.)

To me it sounds like one or several of the components is getting "stressed ".

If the power button doesn't shut it down immediately, it may be on a 4 second time delay.

Oh, one or two other things I thought of. Is the Power Supply being overloaded or not supplying the correct voltages?

Everest in my signature may be able to read information about the temps and voltages. There may also be readouts in the BIOS/Startup configuration settings.

i have already checked temp and fans all are fine the psu is a 470 tr2 which works fine have also tested system on a 550 tr2 still same problem. resolution is only 1024 by 768 and i had no extras active. i have done all the test i can think of and still the same problem. Some times in the event log i can see a bsod code of 0x000000ea. i have also tried a diffrent pic-express grapics card and still a simular problem happens. the on board works fine so im thinking there could be somthing wroung with the pic-e slot on the motherboard; is there a way of testing this.
thanx

 

If you haven't already, get any update for the chipset drivers.

When you about to change from the onboard graphics to the PCI card, go to Control Panel -> Add or Remove Programs and remove the listing for graphics programs. Shut down and put the graphics card in. Power up, if there is any problem getting to the desktop, tap the F8 key to go to the Advanced Options menu. Select to start in VGA mode. Install the drivers when you get to the desktop.

I think you need to remove all traces of the previous graphics software.

i have done all that many time with new and old drives still nothing works.

 

I'm getting low on suggestions. I try everything I can before proclaiming it as bad hardware. Graphics drivers can be very tricky sometimes and might lead you to believe it is a hardware problem. They can get "jammed ", I believe being due to the wrong version of a (common) file being installed. If that theory is correct, the on-board graphics drivers/software has the right version, it is not being overwritten for the add-in graphics.

I suggest booting into Safe Mode, going to Add or Remove Programs and uninstall the graphics programs there. Switch to the onboard graphics, boot back into Normal Mode (or VGA Mode when you use F8), install the driver/software for that...then go back to Safe Mode and uninstall those. Put the new card in and install the drivers/software for that one when you get to the desktop.

I originally saw the problem as "overheating ". I have found that the graphics can get overheated by having a bad set of drivers installed.

There is "sticky" post at the start of the Hardware forum dealing with reinstalling graphics drivers(?). I have never used it, if I want to remove drivers completely, I boot into Safe Mode and check for any listing in Add/Remove Programs, otherwise uninstall the graphics in Device Manager. Graphics is not just drivers, a "managing" program is installed as well.

[If you happen to have a spare hard drive available, swap it with your current system drive, install Windows with the new graphics card installed, that should confirm or deny.]

thanx for your help i have just installed new ati drivers that they brought you but i think it is the cpu over heating. when i ran a stress test the temp went to 67c which is way two high. what i dont get is that if the cpu is over heating why it only does it if there is a grapics card in and not onboard.

 

You don't give us much information. 67*C, when? At startup from a cold start? At startup after a restart? Checked from within Windows?

I would agree 67*C seems high. I won't tell you when I expect it to seem high. A cold boot would be one

Your CPU may not have a good layer of thermal (transfer) compound.

Your graphics seems to "give up ".

CPU or GPU?

I have recently found the bsod's it s giving me:
0x00000ea in windows xp
0x0000116 in windows vista
On any form there is no conclusive solution so im going to have to try and replace my graphics card and if that dont work moutherboard.
