Problems turning on my pc
Ok basically i assembled a new computer about 3 months ago, and everything worked fine until a few days ago when i smelled burning plastic coming out of the psu and it was hot causing the computer to shut down after 15 min of being on.
No big deal i wnet a bought a new one and installed it, but when i switch the power on the light of the mobo turns on for less than a sec (and all ventilators start spining) and then everything shuts down (before any image is even show on screen), there are no beeps on the motherboard. As soon as i connect the power it turns on and off almost inmediatly.
I tried a few things i read on this forum (before posting this thread) like replacing cables, testing different psu's, resetting cmos, changing the cpu fan and i always get the same result.
Here was my original build that worked for about 3 months:
- PSU: 500watts with 24 pin connector
- Mobo: Asus A8N-E
- Video: GeForce 7800gt PCI-E (not overclocked)
- Processor: Athlon 3800+ socket 939 (not overclocked)
- Memory: 4X512mb kingstone Hyper X (2gb total) (default timings)
- Hard disks: Samsung SATA 150 (160gb), Maxtor PATA 30 gb
- Drives: Floppy disk drive, MSI DVD burner, Samsung 52 cd reader
- Addtional data: Cooler: zalman purecopper 120mm fan, Average processor temp 39 degrees celsius, average mobo temp 44 degrees celsius
After the problem started y bought a 680 watts power supply (with a 20 pin conector) and tested it, same result, then bought a 20 to 24 pin adapter and same result, then tested it with a 480 watt unit with 24 pin conector getting always the same result.
