Ok so ive tried everything i can think of so i figured it was about time i asked some one else.

I built my pc about a year and a half ago and been using it happily ever since. Unfortunately yesterday it got hot in my room cause i had a heater running. My pc started to really slow down and wasent running at its best. So i opened it up, cleaned all the dust out of the cpu fan. Which was pretty dusty since it had been a while. I updated windows and the drivers. Its still running slow and when running games the temps get up to 80 degrees Celsius. There is no dust in the heatsink almost at all.

Im not sure what the problem could be at this point, only thoughts is that the thermal paste could not be conducting the heat very well. Its a intel i5 with the stock heatsink. I hadent been able to get some money to replace it yet. Is it possible it needs new thermal paste or could there be something else wrong? If i need new thermal paste i would have to wait a week or two till i have money and id just get a new 3rd party heat sink.

verify the heatsink is connectect prpoerly and has a good seal first(without taking it off).next i would try the reapplication of thermal paste as it is a cheap fix, another thing i was thinking is that it could be a sign that your psu is giving out seeing as it happened so suddenly but first things first, get some thermal paste, im partial to mx-4 and see if that fixes it. to do a reapplication you need 90% alcohol and microfiber cloth you clean the heat sink until all residue is off then you do the same thing to the cpu. just be gentle as you dont want to bend any of the pins on the mother board/ chip, i forget where they are on 775 socket, i believe its the mother board. just gently clean until all residue is gone and you will be...

i would think you just need new thermal paste, and verify your heatsink is placed properly, you could have bumped it when cleaning and now it has an airpocket due to it not being seated correctly. were the temps always an issue or did the randomly just get hotter?

Just as a little side not: make sure your hsf is tight enough. Long ago when I had an old P4 on a stock cooler it got kind of hot, so I took it apart, applied paste, and then put it back together. It turned out to become hotter though for two reasons, 1). Radio shack thermal paste, never again... 2). My hsf wasn't tight enough which jumped it 15 degrees celcius, which was a big deal because this thing naturally runs hot. So that's something to check.

Thats what i was figureing it probably was, will be a little before i can get some thermal paste. Ive never had problems with temps before, this is the first time anything like this has ever happen. Since its a stock heatsink to I have never applied thermal paste either. It already was applied. So another question, before i can put on the new thermal paste what would i have to do before hand. Im guessing i have to take the old grease off. Can this only be done with thermal paste remover?

and most important make sure you use a non magnetic screwdriver to take off heat sink and ground yourself so you dont conduct static electricity

Wait you said about the possibility of the power supply going. Thats a intresting fact because the power supply i got for the machine was a very low budget one and has always rattled and has just been generally bad so it could be a very big possibility that the power supply is the problem. I dont have an extra power suply to be able to test so is there anyway i could figure out if it is the power supply before testing everything with the cpu.

to my knowledge no if your system is having stability issues that is a good way to tell bsod, intermitent power offs, if you give me your system specs i recommend you a good power supply if that is the route you want to take but seeing as it is a stock cooler(from a factory pc?) it is just as likely that the cheap crap they use lost its bond as well

Thanks for the offer but I can pick out a new power supply. I was just short on cash when i first built the computer so i chose to get a cheap one. I been wanting to replace that too. Im about to buy a car so after that ill go ahead and get a new power supply and heatsink. Its not a factory pc, cause by that i guess you mean bought built type thing. I got everything seperate and built it. Ill start with the thermal paste solution and if that doesent solve it ill get myself a new power supply and then a heat sink. Thats for all the Help Bad_Kitty13 and Xavier Wells.

Ohhh well i looked at that list and i have a diablotek and thats a unit 5 which is one they say to replace Asap. So thats defiantly what needs to be done. I checked the heatsink and it came off a little so i reseated it and my cpu temps are good now. Then i checked the gpu and cleaned that out more so the temps cooled even more. So everything ran a little better but it still is giving me a problem. So i checked the voltage on the psu and this is what i got. http://caseyneal.imgur.com/all/ So where it says 12+ volts its only getting 4 and also on the Gpu fan its only running at 30% so thats a sign to me its the Psu.

Thats actually the heatsink i was looking to get once my money comes in. For the time being would i be able to open up my psu and clean it out for now for it to pull some more volts intill i could replace it?

the link you gave says your pics are not public. and if you meant 4a on the 12v rail would be around 48w. but unless you are running a graphic stress test like fur mark it wont pull the amps that it is rated for anyway...i can give you an idea of how many amps your cpu and gpu is supposed to pull on max load if you give me the make model of your cpu/gpu. then you can use prime 95 for cpu and fur mark for gpu to see if it is pulling correct amperage. if that app doesnt display amperage i can try to fond you one anyway. and if you are going to get new psu at least give me your cpu/gpu so i can inform you what power draw you are recieving so you can look for what with safe ratings on the 12v rail

your cpu is 65w/12v=5.42
your gpu is 116w/12v=9.67
your chipset/memory should be around 4a
so your total draw on the 12v rail is 19.09 at max load
your psu is rated to give out a 25a output with a .6a variance so around 24.4a so your psu should be good but giving your psu model it might be close to the limits a good test to run is a furmark test that test cpu and gpu underload, however if it isnt putting out what you need to achieve your rated wattage under max load it could power off your system (or possibly damage your system) so i wouldnt recommend it. your system should be fine until you get a new one as even gaming under max load should only pull 15 to 16a as max system load is only usually achieved under stress tests. when you go to purchase a new psu look for one that has around 24a on the 12v rail and try to get a single 12v rail setup. and try to get one off this list in tier 1 tier 2 or tier 2b(you can cross reference on newegg as they usually have the ratings of the 12v rail)

the cooler you have picked out is one of the best but make sure your case has 159mm of clearance from your cpu to side panel

If thats the case then there must be something else wrong cause i cant play any of my games, after a little bit of them running my fps drops drastically. In league of legends i can get maybe 10-15 mins into a match or sometimes right away my fps will drop from 60 to 10 and i cant play.

Is it possible my Graphics card is over heating. While in a match of league i was only getting 10 fps. The cpu was at a temp of 45 and the gpu was at 65. But it wasent playable.
