Specs: Windows XP
This HP computer has defective capacitors that will go bad after three years. I gave HP a chance to stand behind their product, but the India based HP customer care refused to put me thru to a supervisor. The agent refused to stand behind the defective product and only offered to repair the product for $129.00. I was able to fix the motherboard by replacing the capacitors myself. If you know how to do this, do it yourself and it will only cost about 35 cents for each cap.

Hi, just wondered where you got capacitors like that for $.35 apiece. I'm a ham operator but don't have any capacitors like that in my tool box.

I am having all kinds of trouble with my HP m8300f, and didn't know what the trouble was til I read everybody else was having the same problem. My HP m8300f is only a little over 1 1/2 years old.

Sincerely, proberts4

Hello, yes you can get capacitors at digikey dot com. The bad caps are the ones that have the tops bulging up. You can call digikey on the phone too and ask for tech help when you pick out the caps you need. I also suggest when you go to replace the caps, cut the old ones off, or bend them over and break them off, then re-solder the new ones on over the ends of the old ones. i.e. don't try to un-solder the old ones, the motherboard won't take that much heat. good luck...
p.s. - the caps actually cost 58 cents each and i needed 8 total, so i ordered 10 and the shipping was $5 so it all came to about $15 total.

Hi sorry to bother you. I have the same computer and recently started getting blue screen then restarting. I tried everything even a reformat. after reading your post I looked inside and noticed some bulging caps. I just wanted to know if you were getting the blue screens also. I might call up digikey tomorrow and order some caps, but not sure if that will fix it.

Yes, the symptoms started with freezing up, then blue screen. Then restarting over and over. This is because the caps are shorted out, and when the video card and memory turns on, it overloads the power supply.

Bulging caps are the visible symptom. When you remove the caps, use a soldering iron, and heat up the solder pad while pulling the cap to one side. Be careful not to over heat the solder pads. Also be very careful not to touch the sensitive components on the board.

Have experienced the m8300f failure.. to the point it took out the power supply. Replaced the PS and nothing.. So now I have the mother board out and am looking at ordering the 1800uf 6.3v bulging caps. Plan to replace all 9 of the 1800uf 6.3v. Only 6 are bulging.
Wouldn't it be a good idea to get caps with higher voltage / current ratings? Are these the caps you replaced? Did the computer work after replacement?

Hi,I have the same problem.Put comp in Staples and they told me it was my hard drive so I replaced the 640 hd with a 1TB it worked for 21/2 months and went blue screen. I played with it for 1 week and brought it to bestbuy where after 1 week I was told of the 6 capacitors that went bad.
I also called HP India and got the same thing, only they would not go for the $ 129.00 they wanted $ 350.00 and shipping would be on them (GEE THANKS).
Glad I found this sight THANKS for the info. aceatola@aol.com

Hi, it's aceatola again, I called HPCorporate Head in Palo Alto Ca. and spoke to a Richard they refuse to acknowledge there is a problem with their m8300f.
So I am in the process of filing a complaint against HP with the Attorney General of Ca.
I sent an E-Mail last night and I am waiting for the paperwork to be sent.
I also sent this link to the A.G. as proof that HP knows of this on going problem,
no guarentees but lets see what happens. Good luck to all.

I am also having problems with my hp m8300f. I bought it in March of 2008 and I started having problems with it about April 2010. I replaced the RAM and the problem was fixed (or at least the symptoms were hidden) for about 3 months. Then it went out again and I replaced the RAM. Now my computer won't even run, it just bluescreens.

I also have the M8300f and all I get is the BSOD. I am not knowledgable about replacing the capactors and would like any recommendations for getting these replaced?
