Computer issues

[Capt Quirk]

Back in April, I lost video on my PC. I got a new video card, and it worked for a while, then nothing again. No video post beep, the machine powers up, stuff spins. To make a real long story short, I have replaced the Mobo, the video card, the power supply, and the processor, and I still have no video. Could somebody tell me what is going on here?

Uh...
Monitor?

 

[Capt Quirk]

Tried another monitor, no video there either. The monitor I have been using is black, until you unplug the vid cable, then you get "no signal".

Man... I've poured enough time and money into this to have a brand new PC, and still nothing.

what haven't you replaced?

 

[GenJerDan]

Video card set to send Digital, but you're using analog cable/monitor...or vice-versa.

The cable itself.

Also...unlikely, but... You replaced a bad video card with a video card that went bad, too.

What brand/model card are you using? You should beable to RMA the card and get a new one withen a year.

The original card was an ATI PCIe card. I went to Wal Mart and and got a cheaper replacement, and sent the original back to be RMAd. The replacement also went black. I now have the new card from ATI, and it ain't a working either.

The mobo went back to Abit, they sent a replacement that would light up, but not power on. Got the replacement board last week, but had tweeked some of the pins on the cpu removing/reinstalling it, so I replaced that too.

What hasn't been replaced? Monitor, ram, and HDDs. Even the DVD drive was installed a week or so before all this started.

Typically bad RAM will cause the mobo to beep, but not always. Do you have more than one RAM on the board? If so take one out and try booting.

 

[RokMartian]

Does your motherboard have on-board video? Some of the newer ones do and if using a video card, you might need to disable it in the bios.

Can you see the computer booting up at all?

 

[Capt Quirk]

No onboard video, and only one stick of ram. I will get the post beep if the ram is removed, but no beep for video. There is nothing to see, so I'm not sure if the machine boots or not.

 

[ugafan]

it may be your power supply.

 

[Capt Quirk]

Brand new, bought it just in case...

 

[Capt Quirk]

Just tried a new video cable, and stuck a different stick of ram in. Still nothing. It powers up and there is a tick-tick sound, but no video.

go down to circuit city and get a power supply tester.

if that's good then it's either the mobo or video card. i'm guessing the motherboard.

UGA- The power supply, the mobo, and the video card are all brand new, and so is the prcessor.
