Setup: Customized Dell Studio 540
Motherboard: Dell 0M017G
CPU: Intel Core 2 Quad 8200 @ 2.33 GHz
RAM: 4x1 GB DDR2 PC2-5300U
PSU: BestTec 300W
GPU: AMD Radeon HD 8470 OEM
I've searched for a similar thread and haven't found one, so here it is:
- When I first press the power button, the PC starts and stays on for approximately 5 to 7 seconds. At this point, I have no display, no beeps, no power to USB devices, but the fans are spinning and the hard drive turns on.
- Then, it shuts down and stays off for another 5 to 7 seconds.
- Then, it reboots on its on (The only thing I did at this point, is press the power button once). Again, I have no display, no beeps, no power to USB devices, and every fan spins.
- Then, every single fan except the PSU's starts increasing in speed; the air inside the case is starting to get hot after a minute.
- Then, it gets even hotter and every fan seems to go to its maximum speed. The longer I keep the PC running, the hotter it gets.
Here is a list of things I have tried yet:
- Changed the CR2032 CMOS battery and cleared the CMOS (once changing the jumper and once taking the jumper out)
- Used only one stick of RAM
- Used a different set of RAM (4x512 MB DDR2 PC2-6400U)
- Used a different CPU (Intel Core 2 Duo E5200), removed the graphics card and tried the on-board video
- Used a different, older PSU (500W)
- Tried a different CPU cooler and reapply thermal compound (Stock Intel cooler with Arctic Silver 5)
- Tried taking out the motherboard and putting it on a piece of cardboard
- Tried cleaning every single slot in the motherboard using a compressed air can (including the CPU socket)
- Checked the CPU socket for bent pins or dust
- Tried reseatting the CPU, RAM, graphics card and power connectors (CPU 4 pins and 24 pins)
- Tried running with nothing plugged in, except for the power supply: no RAM, no hard drive, no graphics card, etc.
- Looked for ruined capacitors, but they were all good
- Let the PC run for an hour
- Tried taking out all the RAM to see if I could get a beep code (no beeps heard and still rebooted)
- Plugged in a USB keyboard and a USB gamepad to see if I could get them to turn on (no power/lights)
I've put a lot of hours into diagnosing and still, absolutely no progress has been made.
If you guys have any recommendations, please let me know. I'm desperate to make this PC work again.
Thank you,
