PC seems strange CMOS checksum error?

Having problems with a Acer T120.

I found a vga dell lcd monitor that looked okay on the curb. So, I took it home and plug it in, it seemed okay, so I attached it to the downstairs pc. When powered on, no image. Monitor will turn on then it has this weird blue line on the very top. I swapped the monitors and the acer monitor would do the SAME thing. Nothing on the screen but a blue line on top.

I bought a new vga cable, that was not the issue. So, all I can think of was to buy a low profile video card. Mostly because I dunno what else to do. The monitor is connected to the video card and it works kind of. Some issues came up with the "installed" video card.

This is the video card:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814125346

On post, everything was enlarged and cut off but I could see the screen. I tried installing the drivers for the video card and it would not yet me. It said I needed Admin. rights. This is for Windows XP and their is only 1 account to the computer. But I can SEE something on the screen so that's important. I think swapping the vga cable broke the video port on the mobo. I thought it was okay because I had both monitors plugged in to the surge protector. I first had the VGA cable attached to the dell monitor then removed it and tried putting it on to the acer monitor.

It's okay now, but it seems slower in performance. Also this came up:

CMOS checksum error
Warning! Now system is in SAFE MODE. Please re-setting CPU Frequency in the CMOS setup? F1 to continue to SAFE MODE.

After hitting F1 windows loads. It's working like usual but it feels off? Not very specific issue, but it is slower than usual.

Can someone help me understand what is wrong? I am unfamiliar to CMOS andI do not know why I cannot install the video card drivers?

Also it says on startup New Hardware detected. Now this seems strange "HD Audio"?

Thank you in Advance.

For the CMOS checksum error, i would replace the CMOS battery as it could be going out. Here is guide on how you would do it. After replacing the CMOS battery and hopefully windows boots properly, i would update all your drivers.

I would reset the CMOS, perhaps replace the battery like killer suggested, but more importantly, I would try the old monitor on the computer. There could be a very good reason that monitor was on the curb in the first place, there could be a short in it which may cause some of the issues you are having.

Yeah, the monitor did something to the mobo vga. With the video card the monitor I have works again via vga. I'm putting the one I found to the curb. Or make something out of it.

Just a battery change is welcomed. I will try that.

But what about the admin rights? That is odd and why "hd audio"? I'm trying to install a video card.

The monitor likely has a short, which drew to much power from the onboard video which is what caused the damage. As far as the HD audio, your video card comes with an onboard high defintion sound card, to allow you to stream both video signal and sound throught the HDMI port. Virtually all modern video cards have this feature.

For your checksum error, Try going into your BIOS (usually the f12 or del key on startup) choose load fail safe defaults, then exit and save changes. If that doesnt fix the problem, go ahead and change out your CMOS battery, their fairly easy to replace, just remove the old one and either write down the part number or bring it to your local computer shop/watch shop/wal-mart and find a matching one.

As for the administrator account, there is still one though it may be hidden. You can access it (assumimg its not password protected or you have the password) by pressing f8 on startup, and going into safe mode, on the login screen for safe mode, administrator should appear. Go into administrator and follow these steps:

•Right-click on My Computer

•Click on Manage

•Expand Local Users and Groups

•Click on Groups

•Double click on Administrators

•Click on Add

•Enter the account name on this machine that you want to assign administrative privileges to.

•OK your way back out.

Then reboot your machine normally, and see if that fixes the problem.

I do not see that listed?

This is a non admin account. Only account on computer. •Expand Local Users and Groups is hidden from me.

Well, theres always the ol fail safe, wait until windows is booting (you see that loading screen) and pull the power plug, windows should give you a boot menu that gives you the option of safe mode on the next boot. As far as the CMOS battery, yes all that should be involved in that regards is replacing the battery-which is normally about 5 bucks.
