Downloaded and installed Windows 7. Been running Vista Home Premium with no problems. However, during the install (Dell Optiplex GX620)....almost complete and got a "input not approved"error floating on the screen. Nothing else. I rebooted choosing F8, and finally used the lowerresolution option and it finished installing. NOW...I'm not sure if this is the cause of the rest of the problems or not. I'm about to reformat andtry again.BUT.....everything loads up fine. But during the day, I will have for no apparent reason, it just go black, then into a blue screen. Messages are there, but not long enough to read what is causing it. Does not seem to be related to anything I'm doing. Completely random at this point.Very frustratingbecause when it is working, I love what Isee so far. But the Blue Screens I'm afraid will cause me to bail out of the BETA TEST until and if I can come across what is causing them.I realize there arethousands of combinations of computers, software, hardware, on and on and on and to narrow it down this soon into thebeta release may be a bit much to ask for.And lastly, the shut down part has never worked. No matter what option I choose, shutdown, or restart...it blue screens. It does not shut down in a managed way.SO...for now. I'm going to reformat and try again. Just thought I would throw out there what I've experienced so far.

After the install, did you run Microsoft Updates to look for a video card update? Plus if you think this is a bug please send it to the dev teams using the "send feedback" link next to the minimize button. : )

Yes, I have done all the UPDATES that I know to do. Yes, I think it's a bug, especially on the initial install. You're kinda left out in the dark with that error popping up like that, with no alternatives listed.After several attempts, and choosing the SAFE BOOT option, then finally noticing (my bad), the option to try and lower resolution...did I finally get it to install. I'm wondering if through all that, something didn't get corrupted in the install. Anyway, like I mentioned, I'm not that far along into it, that I can't start over which is what I think I will do. If the same blue screens continue after that, then maybe that will tell them something.I do send feedback every chance I get. I have no idea who and if anyone is getting or reading them, but I do send them, in the hopes that it will help in resolving these issues for the future.Thank you for your quick reply. I will try the reinstall and post here, but I find out.

Well I hope that the reinstall goes better for you, and the feedback goes into the dev teams database, so that they can see the problems without having to dive through these forums.

Try to do a memory test to ensure that your BSODs are not being caused by a bad module. Click the Start orb and at the search box type "mem." Run the memory diag tool as see what it reports.

Good luck with the reformat. As for the memory testing I would recommend that you download memtest86 (easily found on the net) That program picked up an error with one of my ram modules that the Windows memory checker never caught (I was having random BSODs at the time) This was under Vista x64 SP1, I don't know if the memory checker has been updated with W7 but at least it gives you another option.Asrock K8NF6P, AMD64 3200+, 1.5GB RAM, 500GB Maxtor SataII ,Asus 1814BLT optical

Yeah, there is a strange refresh rate issue that occurs during install I would say 1 out of every 5 attempts on both of my test PCs. I've never attempted to go into low-res mode to fix this, and frankly, I think it's safe to assume that since the refresh rate was wrong during your install, something else might be as well. I also think it is safe to assume that you should reformat and reinstall.

Hey everyone. Well, I did do a complete reformat, and resintall, with exactly the same problem. I'm assuming the install was either finished or very near finished when I got the "Input Not Supported" error. I left it along for several minutes, seeing if it would produce any other errors, or reboot, but it did not. So, I power the machine off, then turned it back on and pressed the F8 key, to boot into SAFE MODE, and took the low resolution option to continue the boot. It did then come back up and finished installing. I changed the screen resolution, and everything seems to be working again. I have noticed far fews blue screens at this point. I am using a DELL Optiplex GX620 computer w/2GB's of MEMORY, and an ACER V193 19" flat screen monitor. Not sure what's up with that, but it certainly should be something for Microsoft to look at before releasing (yes, feedback has been left).

try going to support.dell.com and download the latest video drivers from there. Either 32 or 64 bit depending on the Beta you installed

Okay, this is obviously the culprit. The video card is an integrated Intel (R) 82945G Express Chipset Family (Microsoft Corporation WDDM1.0). DELL does not have even a VISTA driver for it, even though I've been running Vista Home Premium with no problems. Intel's web-site, although lists drivers, but when I go to install, it comes up with OS not supported error. SO, I presume this is the root of my problem. However, even though I suppose all indications, are that this machine with it's components, are not going to work with anything other than XP for sure....I would still like to see some sort of warning come up immediately during the installation (of Windows-7, or even Vista for that matter), or some other way to exit the installation, other than the "floating" "INPUT NOT SUPPORTED" message. Just my opinion.
