Hi Chris, I don't have an answer, but it appear the messages may be linked to a failed install as the are in the temp folder. C:/Document1/KEN/LOCALS~1/TEMP/WER3576.DIR001MINI010305.OIDMP The ~ generally is a indication of a automatic backup; possible due to the hardware problems. Here is an article on power supplies; Power Supply Reference Sheet posted by Thor Here are the ATX allowances for power supply voltage spec deviation: +12V DC output +/- 5% (11.4V to 12.6V) +5V DC output +/- 5% (4.75V to 5.25V) If measurements show that the voltage deviations are outside the ranges specified above, then it's time to get a new power supply. *** A digital portable voltmeter is about $20 which you can find in almost any hardware store. You want the one with the pointed contacts not the clips to test the 4 pin connectors. OK the point of all this is that lets say that you had a hard drive gone bad or are called to fix somebodies else's pc where their hard drive has gone bad and in both examples the drives were relatively new or even just a year old. Reminder. Be sure to get a DIGITAL meter. ie not the kind with the needle display. Before I risk putting in a new $100 drive I ALWAYS test at least the +5 volt line that would plug into the hard drive. Yes, I'll often find that in systems where the hard drive seemed to fail prematurely within a year that the +5 volt line is reading 5.35 or 5.4 and in that case I'm NOT going take the chance and toast the new hardware. In this instance/example a new PS is a must in my opinion. Note that as power supplies fail the voltage on the five volt line goes up and that's one of the killers of HDDs. Many bios's also have a voltage reporting section but it's still nice to have the meter as your FIRST opinion. Popular places to find it in the bios is either on the chipset or power page. Use the BIOS as your SECOND data point, if at all. Let's go through an example on how to do this. Your meter should have a red and a black probe so you can stick them in the 4 pin power connector. The wires are colored as follows: Red | Black | Black | Yellow The Red wire is +5 volts. The Yellow wire is +12 volts. Both black wires are ground. With the pc on, put the red probe in the red hole and the black probe in the black hole and read the voltage. Healthy pcs will generally show perhaps 5.05 or 5.11 volts which is fine and well within the tolerance. If you test the 12 volt line you will generally find it OK even if the 5 volt is outside the tolerance. Which is why I said the five volt seems to be the one that really matters when dealing with failed drives.

He has a P4, 512mb RAM, using XP. His comp keeps re-booting. He gets a message about recovering from a serious error. His local comp guru has so far changed his motherboard, RAM, CPU, video card and he got a new tower not including power supply. Each time something is replaced, it works fine for a day or two, and then it starts again. This latest time the error message was - BC Code: 10000050 BCP1: FFFFFFFF BCP2: 00000000 BCP3: FFFFFFFF BCP4: 00000000 OSVER 5-_1_2600SP:2_p Product 256-1 C:/Document1/KEN/LOCALS~1/TEMP/WER3576.DIR001MINI010305.OIDMP C:/DOCUME~1/KEN/LOCALS~1/TEMP/WER357.DIR00/SYSDATA_XML. The other thing is his screen goes discoloured around the edges of the monitor when these problems happen. Any ideas? thanks chrisP For a web-based membership management utility and information on list policies, please see http://nibec.com/24hoursupport/ To unsubscribe, send a blank email to 24hoursupport-request@xxxxxxxxxxxxx with "unsubscribe" (without quotes) in the subject.
