| Jerry <Jerry@JerryThinks.com>: Aug 13 11:58AM -0700 I have a Powerspec B639 desktop that has a bad motherboard. Runs Win 7 Pro Seems that the video portion has gone bad and is shorting out the PS. PS resets after a brief powerdown. (not original PS, installed a better one) So looking for one of the following a replacement motherboard that has Win 7 Pro drivers. this is a must as I cannot go to a later Windows OS ! a way to disconnect power on the MB going to the on-board video so I can try a plug in video card that I have and has Win 7 drivers. any other suggestions appreciated. Thanks ! |

The OS drivers are on the HDD. Just replace the motherboard with a close rev and be prepared to reset the bios settings at start-up to the default values at least once, before inputing your own changes and preferences on a later boot cycle. The default start-up settings will make sure that any board enhancements are recognized by the operating system. If the MB bios is older than on your previous MB, you may consider reflashing it to a more current rev, but unlikely on products mfred after ~2008. RL |

I did see one of the ones like that without the hard drive for about $ 100 shipped. As I do not need 'gameing speed' I have bought about 5 or 6 refurbished computers off ebay over the last 10 years. All but one is still working fine. Some were bought just to get a slightly faster computer with Win 10 on them because Turbo Tax quit working on other systems. |
| Ralph <Ralph@Ralph.com>: Aug 13 11:03AM -0700 I have a remote control car that has a dedicated control and receiver at some unknown to me frequency. Not bluetooth or wifi. It was a Christmas toy. It is a substantial car nearly 18" long. It uses a 8.4v nicad battery that I cannot find and really want to NOT use. I can get the battery specs if needed. The car is on vacation in the mountains right now. lol I want to replace with Li Ion cell type. I need help designing the replacement. Suggestions or instruction please. |

I use a Dremel with a small stone wheel. With the die exposed, it's much easier to melt the solder under the IC from the top with hot air. I use solder paste with lead (still available) to install the new chip and it has a lower melting point than the original solder, so installing it will take less heat/time than if you used lead-free. You have a schematic for the TCON??? Wow, it's nearly impossible around here to get a schematic much less a block diagram. |
