Hi everyone, I'm new here and not great with trouble shooting problems that I'm having.This is the second computer in a years time that did this, and both were less than two years old when the problems started..This is a HP pavilion P6310Y with Violet6-GL8E mother board. Has intergrated 9100 Nevidia grapics and the ADM Athlon llx4 630 Quad Core prosesser. Has 300-W psu and 6Gb DDR 3 memory with a 1 Terobyte 3.0gb/sec and 5400rpm hard drive. First thing to happen was computer startes shuting down while in use.Thought it was thermo related and cleaned fans, heat sinks (were dusty) and re-checked all plugs.Tried all the recommended tricks mentioned on-line to reset things to no avail. Changed out the psu witch didn't help. Puter will come on and fans turn on and I think the hard drive is working. All cd-rom drives seem to work as the doors open and close.. Just get a message on the monitor saying No Signal and then it shuts down as if in sleep mode. And neither the mouse or key board are working. Would the grapics card (intergrated in this case ) cause these problems?And if so I think there's a slot inside for another card to be installed that might over-ride the intergrated one.I did remove the heat sink and fan from the cpu for cleanning and tried not to remove any of the thermo paste in doing so. Re-set all memory STICKS ect. I bet we're looking at a bad cpu or mob aren't we? Thanks for an help on this guy'sIf it's happening on 2 different systems you should stop looking for zebras.

Boot to safe mode. Does the PROBLEM occur there?Hi, And thanks for quick reply...Can't get it to boot to safe mode Don;t think it's posting and with no monitor, I wouldn't know if it was. Tried to power on and press f8 but nothings happening. Thanks...Oh, And I'm lost on you'r comment about looking for zebra's..Are you saying I should check my outlet wireing in the room? If so, it's showing 121.2 volts...Thanks againDon't guess anyone wants to take a stab at what may be wrong here? Who knows, maybe someone out there knows alittle about these things than I do and can share there kn owlage. Really....any real insight would be appreciated...Do you use a surge protector on your computers? Do you use a UPS (battery backup)? What's your normal routine as far as shutting down vs. leaving the computer running? Do you usually shutdown at night or what? The often suggested method of diagnostics for this type of problem is to reduce the hardware in the computer to it's bare minimum and then see if the problem is STILL evident. If it is not then reintroduce components one at a time to see if it happens at some point. Then you are able to see what it is that is at fault. I note your comment re the re-seating of the ram. However have you tried running it on only one stick. Though i must say that from my own experience that if it is ram associated it normally does not even boot--so i DOUBT it is ram. However in your bare minimum trial i would start the test with only one ram stick. You do not have to physically actually remove some items just DISCONNECT them IE: optical drives. The only software component of your computer that i see likely causing this would be power settings which i assume you have checked. Even with that if it happens randomly (as to the time interval) i don't see that being the cause. truenorthIf you have gone through a couple of computers, and may be a few monitors, in a few years, you might have a serious electrical problem in your home or in your area. You may need an electrician to check it out. The first thing I would do is to buy a good UPS. All of the better brands have good surge protection besides having battery back up. Then start trouble shooting your problems. Other wise you may just blow out other equipment.Quote from: rthompson80819 on January 28, 2011, 11:48:19 AM
