Solve : Hardware: Boot Problems., Power Supply?? |
|
Answer» Compaq Evo D51c (HP lists as D510 Minitower) Previously: TIME seems to have made the problem worse. Originally, I could get to the RAM check with some jimmy rigging. I could not boot, but I did verify the problem is not RAM related. Currently: No self test POST beeps. BLACK screen only. Checked the power supply and came up with weird values: Compaq 220 watts power supply, PFC, dual voltage OEM Part #277910-001 Replacement part #277979-001 -----------|----------- BRW (5.9V) | BRW (6.0V) -----------|----------- BLU (0.0V) | BRW (6.0V) -----------|----------- BLK (0.0V) | BLK (0.0V) -----------|----------- WHI (0.0V) | RD (10.4V) -----------|----------- BLK (O.0V) | BLK (0.0V) -----------|----------- BLK (O.0V) | RD (10.4V) -----------|----------- BLK (O.0V) | BLK (0.0V) -----------|----------- xxxxxxxxx | GRY(10.3V) -----------|----------- RD (10.4V) | GR (10.3V) -----------|----------- RD (10.4V) | OR (23.3V) -----------|----------- I don't know why the orange line is 23.3V. That makes no sense to me. All the ATX diagrams I have seen show a max of 12V. Also, the Peripheral Power Connectors are outputting 23.3V. Does this mean my power supply is gone? If so, I have spares, but for different comps. What do I need to match so I can make sure another supply will be compatible? Thanks! EstebanIt may or may not be gone but at 220Watts i'd replace it just on principle. There are basically 2 styles ...20 and 24 pin. Since a 24 pin can be used on an older machine i'd suggest that one if you plan on upgrading.Quote from: patio on June 23, 2007, 02:00:18 PM It may or may not be gone but at 220Watts i'd replace it just on principle. I have a COUPLE other supplies. I am not sure how to determine if a PSU will work though. Is it okay if it is a different wattage?why, of course that's why there's such a variety of PSUs out on the market. Seeing as how your computer has a 220W psu, i'd just upgrade that to 300W. You could go to newegg.com for one. They have TONS.Quote from: alexfue12 on June 23, 2007, 04:27:51 PM why, of course that's why there's such a variety of PSUs out on the market.Still no POSTing... I found an older 300W supply of mine. I plugged it in and the crazy thing is that I am getting all the same voltages I posted above +/- 1. Is it possible that my mobo is telling these power supplies to do something different or something. THis makes no sense to me. :/ Should all I be plugging in is the "main" 20 pin cable?

If the voltages are reading different from the PSU manufacturers SPECIFICATIONS I'd SUSPECT the motherboard, if it is indeed a problem. |
