Hello there! How is everyone?

A while ago my HP Media Center PC (P5LP-LE motherboard) had a power supply problem. The computer was on, but there was no display on the monitor. Then when I tried to reboot, nothing would turn on. There was some smokey smell, but it happened all of a sudden; I was not there when this happened. So I am thinking that the PSU just shorted out - no idea why, since the computer was not working hard and it had run for over a year just fine. Mind you, it was an $80 700W PSU. Maybe that had something to do with it. :P

Anyway, today I've been trying to figure out what went wrong. I have since put in a spare power supply, just to test if the old one is broken. With the new PSU the computer turns on but shows no video. Again, the motherboard is a P5LP-LE. The beep code is: 1 short followed by 1 long. What does this beep code mean? I have been trying to find out without success so far. Right now the nVidia 250 GTS video card is not in the tower; I am attempting to use the onboard VGA.

Since the computer does turn on with the new PSU and did not with the old one, I'm suspecting the motherboard is fine.

Any help would be greatly appreciated.

From what Im finding that indicates a memory problem, try reseating your ram, and if you have 2 or more sticks try different combinations in different slots (one at a time)



Primary system: Motherboard: ASUS M4A89GTD PRO/USB3, Processor: AMD Phenom II x4 945, Memory: 16 gigs of Patriot G2 DDR3 1600, Video: AMD Sapphire Nitro R9 380, Storage: 1 WD 500 gig HD, 1 Hitachi 500 gig HD, and Power supply: Coolermaster 750 watt, OS: Windows 10 64 bit. 

Media Center: Motherboard: Gigabyte mp61p-S3, Processor: AMD Athlon 64 x2 6000+, Memory: 6 gigs Patriot DDR2 800, Video: Gigabyte GeForce GT730, Storage: 500 gig Hitachi, PSU: Seasonic M1211 620W full modular, OS: Windows 10.

If I don't reply within 24 hours of your reply, feel free to send me a pm.
