Curious as to what resolution you're playing these games "maxed out" at. Bet its 1024x768, which is not maxed by any means. BeavermanA

Beaverman gets a gold star for being smart.

djspl, I've had it with people who have an attitude that they are offensive and think they know better. I'm an IT worker at a big company that designs maps for GPS devices. My responsibility is to archive data, and guess what? Those data archives are burned to DVD's! Do you know how unreliable ANY media really is? Even tape, floppy's, carving it into stone, paper, HDD's, etc. ALL (!) are unreliable. Should we stop taking backups and processing data because of that? NO! And I deal with these CRC errors as well when Quality Checks have to be done. Guess what? When I see CRC errors, most of the time the disc is dirty or bad, but sometimes, it isn't. When the OP already mentioned it working fine on a different PC (what I do at work as well: CRC errors on 1 PC often don't get regenerated at a different PC) I thought about either heat or RAM. Yes, I use a different approach then most people, but when you deal with CRC errors almost every day, you start thinking differently. So next time, before you start calling people names, you listen to people who have EXPERIENCE!!! A 5-second Google search and then a 2-second copy-paste job is not experience!DirkVDV01

You said it yourself "Guess what? When I see CRC errors, most of the time the disc is dirty or bad, but sometimes, it isn't".

He said the disks worked on his old PC. To you and DirkDVD that might automatically discount any notion of  damaged disks. So committed to this was DirkDVD (whom you are backing up) that he didn't even mention the most common cause of CRC errors (if the error occurs while trying to read an optical disk), the damaged optical disk.

I on the other hand wonder... Is the OP saying 

1) that just yesterday he installed the game on the old PC and today he installed it on his new PC?
Or
2) that he installed the game 2 years ago on his old PC, the disc worked perfectly and has flawlessly performed a million CD key checks, but now the game won't fully install on his new machine?

Maybe I am assuming too much, but I'm thinking that #2 is closer to reality. Therefore, assuming #2, as an IT professional surely you can see that:

A) trying to install the game requires much more from the disk than a simple CD key check at the start of play. A major scratch on the disc might not affect the CD key check, but could easily affect data needed to fully install the program.

AND

B) if there truly were a gap beteween installs, then surely the disk would have a chance to get damaged. The simple, instantaneous act of carelessly setting it down on the wrong surface when switching games could quite possible cause a fatal error to the disk. Now personally i take care of my media, but having helped MANY people with their home PCs at their home I have found that 99.9% of people have no problem just leaving optical discs around, unprotected.

AND

C) if his ram were to blame would he not be getting other errors, or does all of your experience say that his ram is simply not compatible with his Kotor and GTA disks?

Golly, I guess I'm no IT guy though. The OP should probably take your EXPERT advice and looked for the obvious problem of his rig overheating, but only during the installation of Kotor and GTA.Time for him to get some faster fans or buy new memory? After 35 PC builds consisting hundreds of hardware and software combinations over the last 7 years I have yet to see ram errors that show up only upon the reading of specific optical media. Of course all of those PCs I hand built hardly qualifies me to answer a question as complex as a "CRC error while reading an optical disk" question.

Well, we here at "Backyard Computing" still say the OP has either disc or optical drive problems because the OP never stated he had any other problems, like "all my games crash randomly after a minute of gameplay" or "I get these random blue screens for no reason" or " I always get these unexpected program errors and I'm forced to close my applications all the time" or "when gaming my computer just hard freezes" . Where I came up with all of these obscure scenarios? I don't know.

I never called anybody names. I simply presented my argument and told DirkDVD to do the same thing he told me to do. I cut and pasted nothing. I provided a link to back up what I was saying, unlike some posters on these forums who simply spew biased, uninformed answers based something they read somewhere else.

Burned optical DVDs as archives? Of course you know that out of all of the media you mentioned, burned optical media is THE MOST volatile? I did actually know this already, so don't think that just because I'm posting a link that I just learned it. I'm posting a link so that others can read up and determine for themselves if I have any experience in the matter or not.

[QUOTE="rockerebay12"]^djspl

Thanks a bunch for the link. Unfortunately, I cleaned the discs a bunch in between downloads, and though I havn't tried reinstalling in a day or so, the installations all got to 50% within a matter of minutes...no slowdowns at all

guess I'll just try again, but thanks anyways

The CD/DVDs you buy and burn at home are much different than the CD/DVDs that come with games.

Production CD/DVDs that you would buy in a music store or that are found in games are replicated, or pressed from a glass master. They are not burned. They also have a protective coating that keeps minor and some major scratches from harming the reading of the data. Nothing is burned and no dye is used.

Optical media that you buy for your PC is burned with a laser that changes a dye coating. This is a much less reliable method of writing data and this type of media does not have a protective coating. Be aware that this type of media has a limited lifespan due to the nature of the dye.

Both types of media are susceptible to CRC errors, brand new or not. My GTA Vice City disc did not work due to a CRC error right out of the box. A quick trip to the store for a new copy solved the problem. Cleaning the disc can help, or it might not.

All it takes is one little scratch in the wrong spot. Don't leave your game discs sitting around without a case. Just because it still reads a CD key check at the start of play doesn't mean all the data is intact for the next time you need to install it.

I have something you might be interested in too...I'll give you a great deal.

[QUOTE="Gregoroth"]You've probably disabled a modem driver or something along those lines. Just enable the processes again and have a look at all of the descriptions. Don't disable important stuff such as anti virus processes or anything that relates to terms such as 'BT' etc. It may should you the program path as well.trix5817

Your game disk is bad.

Google is so incredible, all I needed to do was type "cyclic redundancy errror" into the search bar. Try it.

What is it I should think twice about? Just because he could PLAY the game with the disk in his old computer doens't mean he can INSTALL the game now.

Can scratches on a disk not happen in between then and now? Do you not realize how careless people are with their disks? He is trying to read data from an  optical disk. 99% of CRC errors when you are trying to do this are due to a damaged disk. It's either the drive or the disk, but his problem does not scream "RAM" right away.

Do you even understand how unreliable optical media is?

If it were system ram don't you think something other than the process of reading data from a disk would be affected? Or is this one of those one time things where his ram is not compatible with reading data from his Kotor disk? You know, because that happens a lot. Or maybe it's his ram overall, it's just that Windows and all of his other software seem to not be affected, even though that software was installed with the same process of reading data from the disk. "My ram works great with my Windows disk, but I tell you my ram hates my Kotor disk". Right.

Maybe you should think twice about posting things yourself?

Hint: most of the time, start with the incredibly obvious.

Your game disk is bad.

[QUOTE="blazethe1"]basicly, if you know NOTHING about computers, it would be helpful for the company you're buying the computer part from to say, yes, this will help you fit in. (nothing against vista, but people shouldn't buy stuff just cus its new and cool)KSlater85

So why use Vista? Maybe you weren't around during the XP/2000 launch era, but this type of stuff happens every time. It takes some time to stabilize an OS. There is not a forum on the planet that hasn't discussed the perils of jumping on the new OS. NOBODY predicted that everything would work perfect at the launch of Vista.

Do you think Nvidia and MS have all of this as a second priority? Do you have any idea how complex these things are? An XBOX 360 has to run XBOX360 software using the same hardware found in every XBOX360. Software for a PC needs to be compatible with a million different types of hardware and software combinations. 

How could Nvidia have done a lot better? You obviously have vast knowledge of driver programming and the steps it takes to release one to the masses. Nvidia has been making drivers for years right? They could have banged this one out in a couple of days. A driver is a driver is a driver. You could have called MS and told them, "hey, Nvidia needs those programming tools in case you guys forgot."
