Solve : I just "built" a computer and it's not working.?

Answer»

Hello,

Well, after having bought components during the past year, I finally have enough to have a functioning computer. I have so far installed all of them, connected a monitor, keyboard and mouse, and turned it on. There is nothing on my screen. I have put cds for the motherboard, video card and Ubuntu into the disk drive and still, nothing appears on the screen. I have no idea as to which of those three I should have tried first. "Everything" is running, but there just isn't anything on my screen. The video card, an 8800 GTS, has two "DVI" ports, I believe, so I had to use an adaptor in order use my monitor. I've tried using each of the ports, in turn, and still, nothing happens. I do not have a floppy drive, nor a sound card, and the mother board is an Asus P5N-E SLI.

Any ideas about what I should do now? Thanks for your time.

SheltonNothing? No diagnostic messages while it boots?Did you check the front panel connectors with the MB manual to make sure there correct?I get no messages whatsoever during the start-up...I haven't installed any software. As I mentioned, I have inserted disks, but nothing happens. Everything appears to be plugged in fine...the video card's fan is running, along with the two cooling fans; the hard disk is spinning, and the cd/dvd drive spins disks. i'd SAY go see a tech, because even little mistakes can prevent a computer form functioning, well for me xD!

just ask the Tech to double check everything and to TELL YOU if there are any problems before FIXING it, cuz then they charging money

Then if the Tech fines the problem try fixing it, if you can't let the specialists here help U!

Well thats all i can sayQuote

The video card, an 8800 GTS, has two "DVI" ports, I believe, so I had to use an adaptor in order use my monitor.

The first suspect...
If the MBoard has onboard video remove the card and hook it up to that and see what happens...
You also did not mention if you are getting any beeps during POST. These will normally give a clue as to what's amiss...Thanks for the advice. Maybe this information will help:

The components:
CASE -- Antec Sonata III
RAM -- Patriot PDC22G6400LLK DDR2 (Two, maybe four, GB)
Processor -- Intel CD2 E8400
Motherboard -- Asus P5N-E SLI
Hard drive -- Western Digital SATA, 500 GB
Power supply -- Antec EA-500
Graphics card -- EVGA e-GeForce 8800 GTS
DVD burner -- Samsung SH-203B
Cooler -- Thermalright Ultra-120 eXtreme, with Noctua fan.

I disconnected everything with the exception of the processor and powered up. There was no beep, but I understand that MANY systems don't ever beep. It doesn't seem that the motherboard has onboard video capabilities. I'd try another vid card and leave the RAM out to see if it does beep...it should.
Power down and put the RAM back in if the beeps work.
Then make sure the thermal compound was applied properly...
InstructionsI took the video card out of my "good" computer in order to try it in the new one; the connector is different, so I couldn't use it. I have disassembled and reassembled this thing too many times to count. Since the other options that I have involve new and/or different components, it seems that I'll now have to take it to a professional. Some of these components are nearly a year old now, so I'm well past the return period. Thanks for the suggestions, but I am at a true roadblock. Once I am able to take it in to the pros, I'll post the resolution here.

Sheltonbest of luckAre you saying you got no beeps while powering up with no RAM installed ? ?If you have a way, go online and down load the manual to this motherboard. It will tell you alot, and you may be overlooking something simple.Update:

The processor was bad. Hopefully I'll have replaced it by next week.

Shelton
