windows xp time and date

If the battery is not at fault it is more than likely that the RTC Chip has gone bad.

Download Prime95.

http://www.mersenne.org/freesoft.htm

Prime95 is used to put your system at full load. You want your system at full load when checking your voltages to ensure your PSU is up to spec. The whole point is to make sure your PSU can handle what your system asks of it. When it is installed run it and go to Options and run the Torture Test. Run the Inplace FFTs (Max Power, Heat and some Ram).
If your PC restarts during this test you have a faulty Power Supply (PSU) and it will need replacing.

Download SpeedFan and check the Voltages and Temps while Prime95 is running.

You will want your 12-volt rail to be within 11.52 to 12.48 during load. This means when you are running your cpu at 100% you do not want to drop below 11.52 or you may experience stability problems including but not limited to system restarts and Windows crashes. For the 5-volt rail, you want it to be within 4.8 to 5.2 to be within the 4% range. As for the 3.3 volt rail, you want it to be within 3.17 to 3.43.

If the 3.3 Volt Rail is OK and you don't want to replace the motherboard just yet try this

Click Start, Run and type in CMD at the command prompt type in
Net stop w32time and press Enter
w32tm /unregister and press Enter
w32tm /unregister and press Enter
w32tm /register and press Enter
Net start w32time and press Enter

Check to see if the time synchronises properly. If it does load this batch file at startup.

Control Panel > Date and time > Time Zone

Be sure there is a checkmark in front of Automatically adjust clock for daylight saving changes.

Control Panel > Date and time > Internet Time

Be sure there is a checkmark in front of Automatically synchronize with an Internet time server.

There are 2 choices:

time.windows.com
time.nist.gov

I recommend [i]time.windows.com[i]

It's fast and easy to synchronize your computer clock to NIST time ....

You can synchronize your computer clock with UTC(NIST). There are two easy ways to connect to NIST, as described below:

# By Internet

This is the method of choice for most computer users. The NIST Internet Time Service (ITS) allows you to quickly synchronize the clock of any computer connected to the Internet. Simple client software allows you to synchronize your clock as often as necessary, and the service is completely free.
# By Telephone

The NIST Automated Computer Time Service (ACTS) allows computers with analog modems to synchronize their clocks by telephone using simple client software. This service is intended for computers that are not connected to the Internet, or that are behind a firewall. It requires making a phone call of less than 1 minute each time you set your clock. The call is long distance outside of the Denver/Boulder, Colorado calling area.

Keep in mind that ACTS only works with analog modems that use ordinary telephone lines. Digital modems, such as Digital Subscriber Line (DSL) and cable modems, cannot connect to ACTS. If your computer has a digital modem, use the Internet Time Service to synchronize to NIST via your Internet connection.

You can also manually set a clock on time using the nist.time.gov web site here:

it that the batch file doesn't help.

avast! Virus Cleaner - free virus removal tool: http://www.avast.com/eng/avast-virus-cleaner.html

Download Spybot - Search & Destroy 1.5.2 and install it. Update it. http://www.safer-networking.org/en/download/index.html

Download avast! and Spybot and run these two programs in Safe Mode.

What about where the time syncs. too. It should read time.windows.com under time properties>internet time.
(if this has been already posted, sorry)

Scroll down until you see "Download the update for Windows XP package now".
Hope this works for you.

Please post back if you have any more problems or questions.

You did do those Scans in Safe Mode as Spybot should have picked up on it.

Have a look at your installed Programs and see if there has been anything added relating to 2007, 2008.

It could be Winfixer if there is anything there.
