HELP!!!Desktop turns on, but NOTHING happens

[jblazea50]

Here's the specs:

MOBO: Gigabyte GA-MA78GM-US2H
CPU: AMD Phenom 9950 Quad Core
RAM: 4gb OCZ PC2 6400 Gold Series
Graphics is built in with the MOBO (ATI Radeon HD 3200)
Hard Drive: Seagate 500GB 32MB cache 7200 RPM 3.5" Barracuda
PSU: Stealth X Stream 500W
Cooling: G-Power Lite Cooler (GH-PDU22-SC)

It's a newly build computer, about a month old. Running x64 7077. Haven't had any prior problems.

Today, when it was turned on about 2 hours ago, it comes on, but nothing shows up on the monitor. I can see and hear the fans running. The DVD drive opens, but closes right away. The power button on the front doesn't light up and I can't turn it off by holding the power button. When it starts, it doesn't make any beeping sounds, but it does make sound like it's reading from hard drive.

I powered off from the back and as soon as I power it back on from the back, it starts again. Still have no screen and can't power on/off using power button in front.

The monitor gives the "No Signal" message. But the monitor works because I was able to connect it to my laptop.

Any help in fixing this issue would be greatly appreciated.

Thanks

Disconnect/remove all devices, reseat the memory and check that the heatsink on the cpu is secure. With all devices disconnected power the machine on. If there is still nothing on the screen try resetting the bios. Report back with an update and we'll go from there.

When you say disconnect/remove all devices, do you mean disconnecting the hard drive, dvd drive from the MOBO?

I reseated the memory with no luck. The heatsink on cpu is secure.

How would I reset the bios if I can't get anything on the screen?

Not an expert on computers so bear with me if I make dumb comments.

I can't get to any screen so I can't start in safe mode.

Yes that's exactly what I mean. As for resetting the bios, this is usually done via a jumper on the mobo. Look in the installation manual and it will tell you how to do this.

i disconnected the hard drive and dvd drive, and left the cpu, mobo, ram, monitor, and power supply connected

nothing changed

looking in the installation manual to reset the bios

Restart the PC, and keep pressing F8 continually until you get a screen/Window, and it will give you different options to start the computer .

What do you mean by this? you have a radeon hd 3200 built into your motherboard :huh:

 

[Hammerhead786]

Hi Anthony, yes his mobo has an onboard chip (integrated graphics). It's very similar to the board in my server.

Thanks hammerhead, thought he meant he had integrated and a radeon hd

Sounds like something being shorted out on the motherboard.

I would go as far as rebuilding this from scratch checking everything as you go, ide cables, sata leads, and power connectors , and only attaching the components you need to install the OS, once installed add other devices one at a time.

Good luck!!

Thank you for your help. Resetting the bios fixed the problem.

I have another question. Why would this occur that I have to reset the bios?

 

[jblazea50]

Thank you for everyone's help. Will rep you guys now.

Glad its working for you.

Haha, I bet you were a little p.o.ed, especially since you said it was a new build. Very glad your pc is back to normal.

Not very many things that I could think of, off the top of my head that would mess your bios up like that. There is malware that could do that, though. Run some malware scans from different apps to be on the safe side that your HDD(s) are clean.

malwarebytes, spybot search and destroy, XoftSpySE are good ones.

hell yeah i was pissed, it's about a month old and it's not used often...only my parents use it for few hours a day for email, internet, and videos

yeah, i will run some scans

thanks

 

[Hammerhead786]

Glad you got it sorted. Could possibly be a bios issue. May be worth checking for an update.

 

[jblazea50]

ok thanks again
