    Well I think it is the motherboard now because I took the motherboard out and physically examined it. I looked on the back and spotted some things on where the cpu is placed. It looks like just random gray material, maybe the thermal paste? Anybody agree?

    You probably don't have the HSF on correctly.

    I've followed this thread since the beginning, and you have no business putting your hands inside a computer, period. I know you'll think that's not constructive, but that doesn't make it any less true.

    One thing Biostar does not mention in its CPU support list is the BIOS versions required to support the different processors. Your CPU is definitely compatible with the board but could there be an off-chance that a BIOS update is required?

    Hopefully others can shed more light on the issue.

    Yeah, you could try starting from the beginning - take everything out from the motherboard, then put some new thermal paste on the CPU and make sure the fan is attached corrrectly and that there is a good contact between them.

    That's a little harsh don't you think... everyone has to start from somewhere!

    I'll try that and CaptainCranky stop being cranky. :D

    Took my cpu fan off and it appears that the paste is dried up. I guess I'll apply some more after I go buy some. I'll return with the results.

    Put new thermal paste on and the parts will power up with only the 20 plus 4 pin main connector in, but with the 4 pin cpu connection in the parts receive power for a split second then shut off.

    Also when I say the cpu gets hot I literally took off the cpu fan and felt if the processor got hot and it did.

    Then you probably still may not have the HSF fan on correctly. Too much thermal compound is as bad as too little.

    What you're telling is that when you hook up the CPU power, ("the 4 pin"), the system quits. If it's not a problem with the HSF, then you've damaged the board, CPU, PSU, or all three.

    My original statement "you have no business putting pour hands inside a computer", while you don't agree with it, is nonetheless factual.

    Less than one percent of shipped electronics parts are defective when shipped. Yet, (I think) more than 5% are returned as "defective".
    People returning things as "defective", make prices go up, not to mention causing the rest of us to wade through pages and pages of their of their bogus, "reviews" at Newegg. It seems that everybody that can't get something to work also has "high technical ability". I tend to equate "very high technical ability" with a "massively inflated ego", and nothing more.

    Now, as harsh as my comments may seem, I really do want your computer to work. I think you haven't "rehearsed" or researched enough before trying to do this task, and you're paying the price.

    I further believe that you need more help than you can hope to receive this, or any other forum. There are certain skills involved with the assembly of electronics equipment, and they're not instinctive, they need to be learned. Most of us tend to take this for granted, since we've built many machines. I've made fatal mistakes in servicing my computers, but that said, I also know when I've made them, and that goes a long way toward not repeating them. So, someone who doesn't know that they've made a mistake in the first place, is in deep caca, IMO.

    A friend that can give you hands on assistance, might prove to be your salvation.

    That said, I'm sure everybody here will continue to assist you in any way we can.

    Okay well I don't think the problem is my cpu fan because I don't see any evidence of the thermal compound on the motherboard, but lets hypothetically say the cpu fan is working perfectly fine what could the problem be. The fans and sata devices are getting power and the parts seem to get power. However I know my power supply might crap out when I put the cpu connection in I have tried another psu and it has not worked. This leaves the cpu which does get hot with the main connection in and I haven't tried it with the cpu power connection in because the system shuts down immediately once turned on. This leads me to believe this is a cpu problem. I had my friend who is pretty good with computers and he agrees that because the fans and other devices receive power that the motherboard should be good, but the power supply is also at fault too.

    So my options are to buy: Cpu and power supply or Cpu, motherboard and power supply. Should I just buy all three to be safe?

    And also Captain I am sorry for driving up prices and believe me I have researched. I waited 1 month before buying the parts and making sure everything was compatible and I was watching tutorials on how to build a computer. I even waited a week once the parts arrived for my experienced computer building friend to come and help me make sure I didn't screw anything up. I am just pulling my hair out trying to find out why this is happening to my computer because my friend just thinks it has been "bad luck". Again if anyone has any useful information on my problems then I would truly appreciate it.

    First, we need to define "hot". A running but idling CPU should only give off a slight "warmth", (at the HSF) and not be anything you would call hot. For this to be true the CPU HSF must be on correctly, with the correct amount of thermal compound. If you substitute the PSU and the system still does the same thing, it makes sense that it's not the PSU. (At least to me). Unless of course you broke the second PSU by putting it into a snorted system. Please check the position of the case standoffs, if there are no solder "lands" around any given hole in the mobo, don't put a standoff post there.

    If this did the exact same thing when the mobo was out of the case, then you may have done static damage to some components. Another possibility is that the CPU is not in its socket correctly.

    The CPU gets hot and I tested this by physically touching it when I turned on the system. I heard about this on another forum to see if the CPU is actually working. When the fan runs the CPU doesn't get fried and it looks like no damage is being done so I don't think it is that. Also during building I was wearing an anti-static bracelet made by Rosewill, but I suppose I still could have done static damage to some components. I have checked the standoffs and all of them fit in a corresponding motherboard hole for screwing. Also I have reseated the CPU many times making sure everything fits and then carefully pulling down the lever until it is secure. So now it looks like the main culprit is the motherboard I presume?

    What was the second PSU you tried? I'm not so sure you can rule out a weak, defective or inadequate PSU.

    The second psu was from a dell system and it runs 375 watts, but keep in mind I did not use my high-end graphics card I was using integrated graphics.

    If the Dell PSU actually delivers 375 watts, it would easily run any board with integrated graphics. Still, it needs to go into another machine to see if it survived the install into yours. Heck, with a 65 Watt CPU, a good 250 watt supply would probably boot and run.

    You could be in that "elite" one percent that received a defective CPU or motherboard, at this point it's getting hard to tell.

    Okay I'll install it into it's original machine and see if it works. I'll get back with the results.

    My original machine would not post with the old power supply, the power button on the front just flashed orange. I guess the power supply got shorted out.

    So it seems the second power supply, the one you used to test with, is bad so you really don't know if the first power supply is any good yet.

    Incidentally, your conclusion is not true. Just because the PC is getting some power doesn't mean the PSU is fine.

    Well I don't think the PSU was bad because it worked in the system before I tried to put it in. So what could have happened during the building/troubleshooting process that could have messed up the second power supply?

    Can't say what's happened with the second PSU, but it's probably because of your quick plugging in/unplugging procedure.
    Either the board has a short or the power supply does.

    What exactly happened to the first set of parts? Your PSU blew up and took the rest of your components with it?

    Are you certain that your CPU is compatible with your motherboard? Is it only compatible with a certain BIOS version, which is newer than the first BIOS made for that board?

    You may well have damaged that board by having the standoff in the incorrect place. Where was it placed in relation to the components on the motherboard? I.e. in the CPU area? If so you may have shorted the CPU, or a capacitor. In the most recent examples of this happening to an inexperienced friend, one of the CPU mosfets blew up.

    That Raidmax power supply isn't likely to be of high quality or reliability, which is why it trashed everything in the first place. A quality PSU wouldn't do that. You'd be wise to invest in a Seasonic S12 or Corsair HX branded power supply. Your computer relies on having stable power going to its components continuously, it's the most important part, don't cheap out.

    First set of parts PSU broke and I just decided to replace the mobo and cpu because my friend who was there said it was likely the CPU and mobo were damaged by the power supply.
    My Cpu is compatible, however I don't know if it needs a BIOS update, but I have reset the Cmos/Bios multiple times. Also, I believe the standoff was around the region of the ram/cpu, but I'll need to double check that. And now with multiple failures I will indeed opt to buy a more reliable PSU and thanks for some suggestions.

    Also my friend says that when he built is computer he didn't use stand-offs. How is that possible? Wouldn't the motherboard short out against the back of the case?

    Just got done reading your whole thread. Your so called "Computer Literate" friend sound like a ruhtard. Have you tryed putting you PSU into the dell to see if the dell will post with the new PSU? if the dell wont post, the looks like you have 2 fried PSUs on your hands. go ahead and open the both up and grab the the wires you can inside to see if this fixes them! but seriously it sounds like your going around in circles with this build. It might be better just to leave it to a professional at this point. and by professional i dont mean "GEEK SQUAD".

    It depends on the case. Some cases have built-in standoffs stamped into the sheet metal of the motherboard tray. A couple of my cases are like that.
