hi guys, ive decided to start a new thread on this cos you're probbly sick of hearing my ramblings in the upgrade thread.
ive installed my new 6600gt card, but its not working right. fs9 plays fine, but games such as doom 3, medal of honour etc, not so good....
im getting horrible lines, missing graphics, and black blocks of colour on the screen! ive tried the latest drivers, all the different settings, and everything else i can think of. ive a couple of ideas, but as im not too knowledgable on these things id love any hints you can give me
this card needs a power supply, which i have connected, but ive just read the booklet (again) and it says to use at least a 300 watt power supply, mines only 250 watt, plus its powering a sound blaster audigy platinum pro, as well as everything else. could this be the problem, the card isnt getting enough power? if so can i measure the output somehow? and how much power do these cards need? my only other idea is that maybe my cpu is too crappy, its a celeron 2.8 r and ive got 512 mb ram. sorry for the long post, but im feelin pretty frustrated. cheers guys, nick

I think that this could be due to an old/new driver clash. Open up Device Manager, click on display adaptors and uninstall the one named after your old video card. Then download Driver Cleaner (google it) and clean up your nVidia drivers, then restart and install the brand new drivers.

This problem wouldn't have come about if you waited and built a new PC from scratch, like I told you to!  ;)

im hanging my head in shame....
ill try the driver thing, cheers mate

I got into the habit these days that if I do a major component change I re-format.  I use all the latest drivers etc or recommended ones, that way I know I have a fresh clean system. Just my way of doing things though.

how do i go about reformating?
ive tried as the mad robster suggested, but its still the same. ive even tried a different power supply, again with no luck...  its really startin to pee me off now...

Detailed guide to how to reformat your hard disk

This should sort everything out, Nick.

Rob.

ive just scoured my spare room, and it appears i dont have have an xp disc. i think i should, but windows was already on my pc when i bought it.(it was a demo machine) does this mean i cant re-format?

I think it does, unless you buy a Win XP disc from PC World or wha'ever  ;D But then that means another

aaaaaaaaaaaaaaarrrrrgggghhhhh! i need a drink!!!!  ive absolutley no idea what to do......i think i will need a new pc after ive kicked this ones ass

Dont panic yet.  I take it its a package PC that you have upgraded.  Lots of these do not come with there own OS disk, but they come with a 'system restore' disk.

You would have to use this in your case.

Restore disks are a personal hate of mine though, they always put a load of crap on your PC that you do not need.  Thats why I build my own systems and have my own OS disk and do it my way!

i cant even find that! is there any way i can 'make' one, or do i need the one that came with my pc? cheers, nick

ps. im calmer now, ive had a beer and a fag...

oh dear....just found this forum, read it and weep....

the amount of people having problems with 6600 gt's is incredible. only wish i'd read this first.  all the reviews i read on this card couldnt praise it enough, but i can  assure you otherwise. my only problem is what to do now.  i'll try a few more things but if i still have no joy then it will be going back to overclockers....

Iits probably your power supply.

Get a new good one. Some PSU, even though they are rated for 500 watts can't produce a stable current.
You said your gpu clock speeds a lower. Its cause the GPU underlocked itself to prevent low voltages from destroying it.

As for an OS, get a XP disc.

Dont read to much into forums when there are problems.  The same thing happened to me.  I had pre-ordered my 6800Ultra and before I received it the forums were fillin up with people with problems.  this was only due to it being a new card and a few teething problems.

When I received mine I put it in, loaded drivers etc and it ran perfectly.  Though I did choose a manufacturer that I knew wasn't having many problems.

People use the forums a lot more for problem solving than they do for saying how good their card is.  This is because most people are too busy playing games on their new cards!!

There are a few 6600GT probs there but there seem to be more 6800GT probs which is worrying as that card has been out a long time and most of the probs sorted.

Anyhow Hopefully you read through the 6600GT probs.  Drivers recommended were either 66.81 or 71.24 drivers, both available from www.Guru3d.com

I will tell you the few glitches I knew about b4 getting my card (Unsure if it will help yours though) :

Turn 'Fastwrites' off in BIOS.  It caused major stuttering on my card.  Known problem on the 6800's not sure about yours though

Get a registry tweek called Coolbits.  When you get this and run it, it will add overclocking functionality to your display properties.  Ensure your 2d and 3d clock speeds are the same (again if they weren't performance was lost)  the newer BIOS versions on the later 6800 sorted this, just check yours to be sure.

Any other problem you have will be down to drivers, software setup and that your PSU is good enough.  Have you run DXdiag and checked that all accelerators, i.e. 2d and 3d are working correctly?

ive got cool bits already, and ive just checked dxdiag- no problems there.....ill try some different drivers and see what happens.  i really want to sort this problem cos i understand these cards are very good when they actually work!!! cheers for your help guys, keep it comin!!!! nick  :)
