Hola Have a customers Compaq Presario 2.4GHz Celeron w/ 1 WD HD/cdRom/floppy. WinXP/640MB RAM (pc2100). Originally she had 128mbRAM , but I upgraded it to 640mb w/Kingston. Her original problem was the pc cutting on and off randomly w/ in the last week or so. I took it home and installed the Kingston, cleaned a couple of virus's, cleaned a ton of spyware/adware and some other typical maintenance. Updated WinXP. Also took out the original psu and popped in a new 420W TT purepower w/18A on the +12V. The original psu had 14A on the +12V. I left the pc on 48 hours for stability....everything cool ...delivered the pc...everything cool...12 hours later she calls and says its doing the same thing ....I have it now and it wont even boot into WinXP...cuts off/on/off/on etc...have tested other HD's...not the issue...unplugged the floppy...not the issue...reseated HSF and tried different HS fan...temps not the issue...I'm at a loss. I see no jumper to reset CMOS. Could it be the mobo battery? Anyone w/ a sugges?

K....found & reset cmos...still cuttin out. Anyone?

Will it post?

 

[JBDan]

nope... well for a split sec every now and then it will

cuts on and off? Is it turning completely off, and then powering back up on it's own, or do you have to turn it on?

Set the date in the BIOS to something strange... Not todays date, but something in the future sometime. See if it maintains that date. If not, I would highly suspect the CMOS battery. Also, swap out RAM with different sticks if possible...

Also, are you leaving any PCI cards while you are testing? I had a PCI modem that was giving me all kinds of problems because it wouldn't go in all the way... Ended up being the problem.

Ahhhh. House power. Do you have a Seasonic Power Angel or multimeter? I'm guessing she is getting dirty power to the machine, and it is falling below the tolerances. If you don't have any test equipment, you could let the customer borrow a UPS (I don't really know if you could do this as per company policy, but as a matter of troubleshooting...), and see if that works for her. I had this problem when I was running just on the brink of overloading my PSU, by the way. 1100 VA UPS worked wonderfully.

Just a thought. I'm still thinking about it.

I have thought about that too....it now does it here at my house as well and I know I dont have any power issues here...gonna pick up a multi tomorrow at the Depot... tx for that

If it's not posting I hate to say this but, take everything out, and put it all back in as if you would building it new...including a reseat of the HSF.

LOL. You caught that before I edited it. Sorry, I reply as I read, so that I don't overwrite ideas in my brains RAM. And I'm been up for way too long, so my RAM is running at like half speed right now.

Another thing, I don't know if you have checked or not, is the power cable going to the computer. Had this problem recently on my server, cause the damn power cable coming from the UPS to the primary PSU wasn't in there all the way... Yay stupid stuff that gets you.

I wish i could be of more help.

My 865PERL Intel board was just acting different, sluggish and not right after SP2 was installed. At Intels site the BIOS can be flashed in Windows. After up-dating the BIOS
all was well once more. I had to clear the CMOS once and could not get on line or find the manual. The battery was removed for an hour than the BIOS was reflashed, that was six
months ago. The batteries last a very long time but it would be a good idea to check it with
a DMM and if it's down even a bit, change it out.

ok got it tx for the replies guys I just trialed and error'd it by unplugging every daNg thing in the case except whats neede to power it up and I deduced it to (of all things and I have never seen this in my repair work) the freeking USB wire that runs from front IO to the mobo. Unplugged it and all is well so far. Tx very much for the responses

 

[Cook1]

Ha!

Always some lil thing like that...gotta love PCs!
