Hello, and thank you for your patience with me on my posting (to both of you who responded)!
You can disregard the comments related to Upgrade from XP to Vista and Windows 7. I should have just stated that I have found proposed resolutions for all three operating systems. Like others who are experiencing the same problem with their Lenovo laptops, and who are trying to find fixes on the web, have come to the same conclusion as myself - none of the suggestions/fixes resolve the error(s) on my G530 after the Windows 7 upgrade from Vista last fall. It was delivered with Vista and as a promo it included the Windows 7 upgrade as an added feature to buy the laptop on the Lenovo Shareholder's site, from which I purchased this laptop at a reasonable price but NO bargain price was paid by the person who bought the laptop for me as a gift (they own Lenovo stock, NOT me, btw).
I've searched every page on Lenovo Support, created several Service Requests with Lenovo and have continued searching for a fix that I can applyworks on my own. No luck.
To properly define the problems: after my upgrade to Win 7 (immediately upon receipt of the gift since the Win 7 discs were included), there are two problems in Device Manager:
1. "Base System Device" - It really is generic error which provides LITTLE to no information as to what this driver does or is associated with in the overall function of the laptop, however, I've found on Lenovo's site that this could be the reason that my wifi connections, at times, just drops for no apparent reason, or possibly that these problems are the reason that the screen freezes randomly when using it. On the "General tab" for the device driver in Device Manager: "Base System Device" appears under "Other devices" in Device Manager. Device Type: Other Devices. Manufacturer: Unknown, Location: PCI bus 2, device 0, function 3." Error below states "The drivers for this device are not installed. (Code 28) There is no driver selected for the device information set or element. To find a driver for this device, click Update Driver." Upon clicking Update Driver, it can't find a solution neither on the net, nor on my laptop. There's nothing on the Details tab in Base System Device Properties and on the last tab, Resources, it only states: "Resource Settings: This device isn't using any resources because it has a problem." I've opened SRs with Lenovo and they're not responding to any of my "Next Day Service" which was purchased with this gift from a friend. Sad that they don't reply. And the Representatives hang up on me when I ask for an address to where I can send the laptop back to them.
2. The second problem that I'm experiencing is a Network Adapter called "MbmLowExt" that is identified as being a product of Ericsson AB and a location of "0000.0014.0000.". The error message on this adapter driver is "This device cannot start. (Code 10) {Operation Failed} The requested operation was unsuccessful" on the General tab, and on the Driver tab it states: Device Provider: Ericsson AB", Driver Date: 10/29/2012, Driver Version: and the Digital Signer: Microsoft Windows Hardware Compatibility Publisher. Clicking on the Details tab shows that the driver files are located in C:\Windows\System32\Drivers\MbmLowExt.sys with the Ericsson AB Provider, File Version and the Digital Signer is the same as is listed above. Finally, on the Events tab (last tab), the Information for this driver states: "Driver Management has concluded the process to add Service MbmLowExt for Device Instance ID USB \VID_0BDB&PID_1926&CDC_0D&MI_06\7&204407CD&2&0006 with the following status: 0." I have no idea what this means and none of this brings up anything on the Net when I google the errors, which I include the machine type & other relevant information.
I'm unable to post screen shots to explain these errors on this site, so I thank you for any thoughts that you may have on this 2nd problem. Between of these two errors in Device Manager, I'm unable to associate "x" problem with Device Driver error 1 or 2, i.e., periodic crashes or frozen screens on the laptop to this device driver error or the first error listed above.
I have, of course, searched Ericsson AB's website thoroughly to try to find an update for this driver, to no avail.
Sadly, Lenovo has stated via telephone that both of these errors are my fault because I've added new software, which isn't true (aside from the Win 7 software that they sent to me!) because I spent the first month that I owned this machine installing NOTHING and trying to resolve these errors, so as to start using the machine with a "clean slate" the machine was delivered with these problems. The rescue and recovery discs are for my machine and Windows 7, so it's not like I can revert back to Vista easily without purchasing a new copy (if it's still available?). My SR's with Lenovo and attempts to ship the machine back to them go unanswered, so now I'm at the point where I'm having my friend dispute the large purchase on his Platinum Credit Card in an attempt to get Lenovo's attention that these problems are not my fault.
This certainly will be my last Lenovo purchase, no matter how much I like the Thinkpad style of laptops.
Once again, thanks for any thoughts that you may have or suggestions as to how I may find solutions to these problems, if any at all. I also appreciate your patience with me and my attempt to describe these errors!

Your errors appear to be that you have Vista or incorrect drivers for your hardware. Riider posted a link to their drivers page, just make sure that you select Windows 7 from the drop down so that you get the correct drivers. I recommend installing all of them over again so that you have the latest for everything. I recommend to never leave choosing drivers to Windows, chance, or any other website but always go directly to the system manufacturer for them (the only exception would be added components on a desktop, then you get them from the component mfg's site).

You have to be a little bit crazy to keep you from going insane.

Thanks for everyone's help! Unfortunately I've not been able to resolve the issue neither by the recommendations on this forum, nor by installing Window 7 again, so Lenovo's getting their laptop back due to poor service for "On-Site, Next Day Service" which was expensive and they still don't reply for weeks-at-a-time so we're disputing the charge on the Platinum card which was used to purchase the machine. I'll never buy any Lenovo product again...this has been an awful experience, sad to say.

I appreciate all of you taking the time to offer assistance!
