Having weird, persistent problems..

Hey all

My System:

ASUS M4A79XTD EVO mobo
8gb DDR3 1600 Kingston HyperX Blue ram
AMD Phenom II X4 945 3.0GHz CPU
ATI Radeon 5770 x2 in crossfire
64 GB Crucial SSD
500 GB seagate HDD
CD/DVD Drive
BFG Tech 650 Watt PSU
Windows 7 Ultimate 64-bit

Just built May-June 2011, never worked perfectly, but nothing terrible. However, now it seems that every day I encounter some error or issue. Anything from Blue Screens(Cache Manager, System Service Exception, Bad Pool Header, and a few others), random crashes/restarts, PC turning on with no video while GPU fan revs forever without ever getting to boot, Freezes while booting or after boot up, and random black screens while doing anything on it.

I have tried taking it somewhere for some outside perspective. They told me that the SSD and a stick of ram was bad, so I removed them and the system appeared to run nicely for about an hour, then the errors came back. I have RMA'd the parts and reinstalled them. They tell me that at their place they have no problems with the pc after stress testing it for a few days. They suggested it might be something external, like wireless mouse and keyboard....ok....so I got wired ones, still having problems.

Yesterday I removed one of the 5770s and the system ran fine for the entire day, no problems what-so-ever. Until it went into sleep mode sometime last night and now this morning it will not boot. It will turn on, lights come on and all, sounds normal, except for the 5770 fan keeps revving with no video on the monitor. It just did it for an hour with no improvement, so I shut it off.

I am completely owned and dumbfounded by this system. All and any help is greatly appreciated. I am leaning towards the problem being mobo related, but that is just a gut feeling.

Thoughts?

Thanks

The only suspect component I see on the list is the BFG Tech PSU. The wattage rating is fine, but BFG is not known for quality, especially the PSUs. If you had another PSU you could sub in, that might help at least eliminate it. The problems you describe could be caused by flaky PSU voltage, or flaky voltage coming from the wall outlet, and even a faulty surge protector.

An 80 plus certified or better PSU from Antec, Corsair, Seasonic, Silverstone or XFX is best for gaming rigs.

Tlmck, I have had that cross my mind as well. Do you(or anyone else) think that the PSU could be causing all these problems? I would really prefer not to buy extra parts if at all possible. Buying just a PSU would be okay, because I agree it is a POS by the eye test. I guess I really did not realize it when my friend gave me it.

Thanks

Quick Question, when you say 80 plus...is there a color associated with it? like bronze or silver?

thanks

80 Plus is minimum, Bronze is the next level and the ones most makers are offering these days, Silver is even higher. http://en.wikipedia.org/wiki/80_PLUS

edit: for your system, a 550w would be minimum, and a 650 watt would be better. Right now, XFX has some of the best deals with rebates.

I have to sign off for a while, but will be back later in the day.

Any of those will be fine. Just a note on the Antec green series. They do not include a power cord, so save the one you have or get a new one. It is that way on purpose as part of the "green" thing.

Occasionally you can find a better deal on Amazon.

Ok thanks. I will go out tomorrow afternoon and get one. I found a place around here(Columbus, OH) that sells computer parts. Hopefully, this will solve all my pc problems!

Update:

Today I went out and bought a new PSU, Cosair GS800 along with 2 new 120 mm antec fans. Installed about 5 seconds ago, and so far, so good. Two start-ups and no boot problems.

Here's to crossing my fingers!!
