Power supply issues, please help

[wrighterjw10]

I believe my power supply is going bad, and before purchasing a new one, I'd like some help. I am not too savvy with PSUs.

Here are my system compentents:

Intel Core 2 Duo E8500 Wolfdale w/ Artic Cooling Freezer 7
ASUS P5Q SE/R LGA 775 Intel P45 ATX
4G Corsair 240 Pin DDR2 SDRAM DR2 800 (PC2 6400)
ASUS EN9800GT Ultimate 512M Geforce PCI Express 2.0 x16
OS: Windows Vista 64bit Ultimate

I was putting my computer to sleep, and when I tried to awake it, nothing happened.

When I try to start it, everything powers on for about 4-5 seconds, then turns off for about 5 seconds, then turns back on, all fans spinning, DVD ROM works, everything is working, but no picture on the screen.

I tried to unplug the harddrives to get to the bios, but the PC won't post to the BIOS.

I think its the power supply? If so, can you reccommend a good one for my system off of newegg?

Thanks in advance, I REALLY need help on this one.

Before you get a new PSU, try taking out the video card and putting it back. Do the same for the RAM sticks.

Do you hear any beeps when the computer starts?

 

[wrighterjw10]

No there is nothing, which makes me think power supply. Beeps usually mean hardware right?

 

[aevm]

Right. Some times you get a combination of short and long beeps and you can look it up in the BIOS documentation to find out what's wrong.

 

[wrighterjw10]

So does it sound like the power supply to you as well?

 

[aevm]

Man, I don't know. It could be the video card too, or the motherboard.

Try reseating the various parts and connectors. If that doesn't change anything, I'd try a new PSU indeed.

Just to clarify: this computer used to work before, right?

 

[wrighterjw10]

Yeah it worked perfectly, its only about a month old, never had any issues. my only guess is i should have upgraded the powersupply when i updated all of these parts.

ERRRR, yeah......

I would recommend a modular PSU as they are just too good an idea and keeps the cable clutter at bay.
