My pc started to turn off after about 2 minutes. Then after 10 seconds, followed by 2 seconds. I figured it was the power supply so I bought a new one. My old one was 600 watts so I bought another 600 watt power supply. It turned out I even bought the same brand, OCZ Technology.
With the new power supply my pc won't even turn on. A couple lights light up on the mother board just like with the old power supply, but my machine won't power on. So I plugged my old power supply back in and it did the same thing as before. My pc would stay on for a couple minutes and shut down and then go down to staying on for a few seconds.
So what's wrong? Are not all power supplies for all pcs? Can it be that the new one isn't compatible? I understand there's always a chance that it was just broken out of the box.
Do I need a new heat sink fan maybe?
- Intel Core 2 Quad Q6600 2.4 ghz OEM
- 4 Gigs of ddr2 ram, 4 sticks of 1 gig each
- XFX nForce 680i LT SLI motherboard
- PCI Express x16 graphics card
- one sata harddrive, 450 gigs
- one 500 gig harddrive (not sure what kind it is. it was external but the casing's power broke so I stuck it in like 3 months ago)
- one dvd dl drive (plan to get another)
- 2 12mm fans, and 2 8mm fans in case
(I am reposting this because I didn't get any answers the last time.)
When it stays on for 2 min, then shuts down and can only stay on for a few seconds, thats a heat problem, not a power problem. Check your temps as I bet your CPU temp will be over 65c. The solution would be to clean your heatsink and make sure you fan is spinning.
The heat sink fan is spinning and I did clean with a can of one of those compressed gas dusters. My theory is that the new power supply is defective and that it is the heat sink fan because I remember it being kinda cheap.
I also did try to connect and power up one component at a time.
I'm not familiar with BIOS or accessing it. I tried to last night and my PC wouldn't stay on long enough to do anything.
I'm going to buy a new heat sink today. Anyone know a good resource on how to replace a heat sink? I'm intimidated to touch it since it's connected to the processor.
