Need build help!!

I just finished building my system. I boot it up an only get a picture for maybe 15 seconds

I think my ati 4850 isnt getting enough power

http://www.newegg.com/Product/Prod [...] 6817194003 <- power supply

I get 2 beeps on start up but i think that is normal

A red light flashes on the 4850 on start up tooo


PLEASE HELP

That isn't a lot of information to go off of. Some things you can try are:

Unplug everything except video card, processor, and 1 stick of ram

make sure everything is seated properly

make sure the 20/24 pin and 4/8 pin connector is hocked up to your mobo

Reseat your heatsink. It could be that your cpu is getting to hot and causing the system to shut down. Also make sure that you have the correct amount of TIM applied

minus the fact where that isn't a very well known brand of power suply (i would consider getting a new one as a crappy power supply can take out your entire system if it decides to give way) it should have more then enough power to power a single 4850

When you get a picture, what is it of? is it just the system posting? can you get into bios?

Thermal grease. did your heatsink have TIM pre-applied on it when you got it, or did you put it on yourself? Also if you can get into the bios and check the temps of your cpu

How do i enter the foxconn bios?

I didnt put on the heat sink properly at first somehow it came loose or i didnt put it in right

Ok right now im 99% sure my heat sink is the problem


When the system shuts down i reboot it really fast to check the cpu temp and it is either 116c or 115c


Do i need new thermal paste?

or

Should I go and buy an aftermarket heatsink

^+1 an after market heatsink will do you wonders, but even the stock heatsink should sufice (but you will need to get some thermal paste)

Your cpu should be idling around 30-40 C so that is defenatally the problem.

When you get a new heatsink or just reseat your old one you will have to wipe off the old thermal paste and apply new thermal paste. To do this you can either use Arctic Cleaner 5, this one will clean the heatsink off better then any other one but will cost more, or just use rubbing alcohol (i would doulbe check this one and make sure there isn't a specific concentration that you need to get). Also i would use coffee filters to wipe off the old paste because they are lint free. You dont want to use anything that will leave lint on the processor during this process

As for the new thermal paste i would recomend getting arctic silver 5. Its relativelly cheap, works great, and has enough for multiple instalations. You can go to http://www.articsilver.com/arctic_ [...] ctions.htm to look at the specific instalation instructions of the new TIM for your processor.

is that 64c under load or idle?!?

64c idle is WAY to hot. If thats the case then either you have the cpu overclocked or the voltage is turned up, or more likely the heatsink still isn't getting proper contact or you used to much thermal grease. You want to use a very small amount of thermal grease, just enough to make a very think layer across the processor (the saying that you will always hear is the thermal grease on your processor should be about 2 grains of uncooked rice).

Get those temps down before you do anything else on your system!

As for the 4850 it can safely run a lot hotter then the processor, and i believe you can change how fast the fan is running on it to get the temps down more if you aren't satisfied with it: http://www.hexus.net/content/item.php?item=14111
