glitchy video windows & games etc

[mun_boy]

Hey, a few days ago i built my own pc and get everything (frivers etc) installed n then run into a problem - the mouse movements are jumpy n glitchy, and videos i try and play are extremely jumpy, freezing every couple of seconds, n games are the same..

i have in it a gigabyte EP45T-UD3LR, intel quad core Q9550, 4gb ddr3 ram, nVidia 9800gt 1gb graphics, 1tb westerd digital hard drive.

i originally thought it was the operating system, but i bought a brand new xp operating system n tried that n still nothing, then tried fideling with the graphics settings but still nothing

if anyone has had this problem or has any suggestions as to how to fix it, it would be greatly appreciated.

Hi mun_boy and welcome to TSF,

Sounds like you have missed your graphical drivers. Make sure they have been properly installed. Use my sig to get the latest Nvidia drivers.

[mun_boy]

thanx karlos for ur quick reply but my drivers were installed from the cd straight after the motherboard one:
driver version - 178.24
stream processors - 112
core clock - 702mhz
memory clock - 900mhz (1800mhz data rate)
memory interface - 256bit
memory - 1024mb
Vidoe Bios version - 62.92.6D.00.07
IRQ - 16
Bus - PCI express x16 Gen2

thats the system info..

i seen a few other posts on here with similar problems, tried following a few of the things but have not worked.. its hard to expalin what it happening but its really annoying, it will even do it while im typing (like freeze up momentarily) n ill loose a whole line of words.. would it be the graphics card or could it be something else.. like the divx ive installed or something? iunno.. i thought i knew a bit about computers but apparently not haha

Open up Task Manager and see if there are any processes that are using 100% of your CPU.

[mun_boy]

cpu usage is at 0%? so its happening for basically no reason?? (well there must be one i suppose..)

maybe could you post a screenshot of your msconfig
start
run
type "msconfig"

go to the startup tab and post a screenshot of it

also maybe post a screenshot of your installed programs

What make/model is your Power Supply?

[mun_boy]

the power supply is a "WideTECH" ATX650W..

[Aus_Karlos]

This PSU does not have the required wattage or amperage to your run PC. It has barely enough power to run the card by itself. Its stated that the PSU only has 70% efficiency which brings the total output to 550W.
Attempting to run your PC under gaming conditions in its current state could damage hardware components.

To run a 9800GTX you require at least a 800W PSU with 32A on the 12v line (I recommend 850W 12v @ 40A to minimize PSU stress)

I would say runnig a 9800GTX requires at least a corsair 650w
and a corsair 750w is recommended

[mun_boy]

so what makes my power supply so bad.. its a 650W and got heaps of spare power slots... n the graphics card only takes 2 inputs anyway?? how would another power supply do it any different?

[Mcninjaguy]

ita rated at 25C for its full load a good PUS is rated at 50C
it has dual rails with about 30% less amperage than the same wattage PSU by Corsair 650w)

big big difference in quality
never ever buy a cheap PSU and expect any decent performance or reliability

[mun_boy]

thanx, got a PSU on order, ill post back if it works or not... hope it does.. lol

[Tiber Septim]

Mind telling us which PSU you have ordered? Was it one of the ones Aus_Karlos recommended?

[mun_boy]

it was one of the ones he recomended, cost like 280, um, 1 x 850W Corsair TX-850 ATX Power Supply, 140mm fan, Dual PCI-E Grap

[Mcninjaguy]

good choice you can put any graphics card (if you want to upgrade) into that system now

keep us updated

[mun_boy]

ok, so i got the PSU yesterday and installed it last night, been mucking round with it this morning n its still doing the whole glitchy thing, ... i noticed there was a driver out so i installed that but still no change..

[mun_boy]

*new driver out (182.50 or something)
