New System < 3 months old won't always POST

Nihilist · 02-24-2009, 08:22 PM

Hey all,
I'm kind of in the dark as of the last month or so. I put an expensive gaming rig together about 3 months ago and it ran fine up until about the last month or month and a half ago. Now I have random lock ups, restarts, blue screens, and also when I go to reboot or just start the system up the led lights on the front of the case light up momentarily then go off, and then the computer doesn't beep and try and POST. I can eventually get it to POST after numerous trying sometime lasting 10-15 of restarts. Most of my hardware I would be able to RMA but I just don't know where to start. I did run memtest on my memory and I did get errors the first time I test all four modules, but when I tested them independently they all passed with no errors. System specs are as follows.

Vista Ultimate 64
2 Visiontek Radeon HD4870x2's running in quad CrossfireX
ASUS M3A79-T Deluxe AM2+/AM2 AMD 790FX ATX AMD Motherboard
AMD Phenom 9950 Agena 2.6GHz Socket AM2+ 125W Quad-Core Black Edition Processor
8GB Corsair Dominator DDR2 (1066)
500GB Western Digital Cavier HD
LG DVDRW drive
1200 watt Coolmax PSU

Any suggestions would be helpful as that I'm starting to get down about the situation.

Thanks!

When your have trouble getting it to post, then do get in head to the Bios and have a look at the voltages, 3.3v,5v,12v and the CPU and MB temp.

did you overclock your system? try it with 1 video card.

I agree with Speedster try it for a bit using only 1 card.
