Horrible Flickering/CPU Usage...?

Question

I recently started having alot of problems with my visuals with my computer, while playing games more notably the textures would tear and flicker but after enabling bios shadowing it stopped, a few days ago it started again and now after about an hour or so it gets so bad my monitor turns off and resets the screen, it gets miscolored, the desktop flickers and my CPU usage goes up and down, i dont have many processes running but system idle process seems to be 99 under the CPU category on the task manager, the specs for my comp are as follows;

Intel Pentium 4 3.20 GHz
1024 MB single channel DDR 400MHz RAM PC3200
nVidia Geforce 6800 GS

i've tried alot of things, new RAM didnt work, i doubt its my video card, its not the monitor, so im thinking it has to do with my operating system itsself, i updated my drivers, i fixed my registry, defrag'd, checked for disk errors...everything, virus scanned.
occasionaly it cuts to the blue screen and dumps my physical memory.

i've also set my Refresh rate to 85Hz, it was at 60 at the time of posting the question, but this only lowered the flickering it still is there.

okay, i completely removed the driver, downloaded the latest one, and it still flickers, it seems to get worse with usage yes, i disabled shadowing too and that made it a bit worse. could it be that im using a CRT monitor and not a LCD? maybe i should plug a flatscreen in and try that one out? the flicker is like, lines across the screen, and sometimes it disorients the text on the screen, its almost as if the monitor cant keep up with the video

okay i just plugged in a flatscreen LCD monitor, and there is no diffrence or change in the ammount of flickering, does that mean theres something wrong with my video card?

Answer 1

There's one key point to the details you provide ...
... that it gets progressively worse with usage.

This tells me that there is a hardware problem with the video adapter or the monitor ... probably a chip or circuit overheating.
The operating system doesn't deteriorate as you use it .... there has to be a physical factor involved.

There is a small chance that the video card driver is corrupted. This would also cause such symptoms. Try updating it.

YEP .... it looks like the video card is the problem.

nicely there are surely quite some procedures. I surely have not yet examine the different solutions so if I repeat some I make an apology. There are some organizations like Verizon which have a cellular telephone plan. What they do is once you get your baby the phone you've some telephone numbers programmed in (purely those that you want him to be able to call) and those are the purely human beings he can call on his telephone. Now any volume can call him and it is going to flow instantly to voice mail so its like a messaging service there. also i trust this plan comes with textual content messaging (necessary for the more youthful ones of today lol) like limitless or something and he may be able to textual content message each person and recieve them from each person. My mom were given it for my cousin and it purely value an extra $10 a month to characteristic it to her pre-present plan. yet another direction you are able to take is a few telephone organizations have parental administration features on cell phones. you are able to enable him to purely make call at certain situations, purely call certain numbers, purely use a particular quantity of minutes, etc. and that i trust there are even procedures of going surfing to bump up/decrease the minutes whenever you want on some. tremendous thanks to encourage to do abode artwork and such. If he does his chores he receives extra minutes. If he receives an F in a type his minutes get decreased. i trust Cingular/ATT has a telephone like that and probably T-cellular as well. there are countless tremendous innovations to come back to a call from you purely ought to discover whats acceptable for you. good success =)

try a lower res. to see if that works. if its only in 3d, such as games, probably a driver issue. All shadowing needs to be disabled in bios with highend cards.direct x files up to date? start/run dxdiag.exe. start with that...
