Hi,

I built my pc yesterday booted first time, installed windows everything was fine apart from a graphics driver problem where the screen would freeze, and then say, the graphics driver has failed and been recovered successfully.

I turned the machine off. And had a look online, the most probable cause that is was being underpowered within the windows settings (I have a 650w XFX PSU) so thought I would try this.

When I came to boot my machine again it would not start. The fans spin up momenterally and then stop instantly. I have unplugged hard drives and gpu but still the same. I have not yet taken everything out etc or tried the PSU with another machine but my hunch is the PSU is at fault.

Any ideas?

Thanks for your help
 
Just seen something somewhere about the not having all motherboard screws in. I dont have 'A' & B' screws in as i count get to them after the case fans were installed. I will try this when I get home tonight but could this cause such a problem?
 
could be you need to check that for every motherboard stand you have under the mobo you have a screw to connect it to the motherboard otherwise it could cause a short.

are all the required power connectors plugged into motherboard, graphics card etc securly ?
 
Hi,

Yer, I am going to try this tonight, will take everything out and just leave mobo and cpu fan and screw every screw in. I think this may be the cause but it was working like this before so i dont know.

I unplugged the gpu completly but still no joy.
 
If it isn't too much hasle, I would take it all out, and build it outside the system. It gives you more room to play with (especially if you have a tight case) and will make it easier to diagnose the fault.

There could be a 100 different reasons causing the fault, and the only way to find out, is strip the system back to basics, and find out what is causing it.

I would use this - http://extreme.outervision.com/psucalculatorlite.jsp to calculate your system power consumption. If the 650w covers it, then you are fine there.

Then have a look at this - http://www.buildyourown.org.uk/pc-building/troubleshooting/ I used this mini guide when I was building my PC to help me diagnose the problem (mine was I was actually turning the PSU "off" and not "on" at the switch at the back, so stupid :D

I would double & triple check everything before you send a PSU back. The last thing you want to do is send it back, then find out the new one does the same.

Good luck with it all :)
 
Thanks, how exactly do I build it outside the system?

I ask as if he problem is that the screws are not grounding the mobo surely there would be no screws at all!!!??? Noob question im sure!

Also, how tight should the mobo screws be?

The case is what causes the short and the issues, due to it being metal.

I built mine outside the case on the mobo box that I had. Never had any problems with it at all.

If you can, keep your case nearby, so you can plug in your LED's, Switch, and Speaker (if you have one, so you can listen for the POST noises). Just makes it easier to see if your system is actually on (and working). I had a cheap motherboard test kit which was only a 5er from a local electrical parts store (just had the LED's, Switches, and Speaker on).

Thanks for your help, so it is ok to build the system on say the box the mobo came in?

Thanks

best way to do it imho, saves wasting time putting everything in the case only to find out you've got a faulty part.

i've done all my full new builds/new mobo like that since i had the old mobo stand issues a while back.
 
And one final tip, stay calm :D

It will likely be something "silly". A lot of the problems with system builds are minor errors, or something not corrected properly, I am sure even experienced builders do it from time to time.

It is unlikely a faulty part, as most of the problems I've seen on here, have been something not correct the way it should be. Only when you are absolutely 100% sure should you send something back :)
 
Yes, this does make sense, its a real shame, I was so annoyed last night! The pc seems ultra fast, was so excited about fixing the graphics issue and playing some games and then this!!!

Hey ho,

will try this tonight and let you know the outcome.

Thanks again
