Hi Guys, wonder if any of you can point me in the right direction to identify an intermittent problem I have. Sometimes, when I start up the PC, it appears to start ok, all lights and fan etc come on, but I get nothing on my monitor screen. It may take 1 or sometimes a few attempts at turning off and then back on, for it to start normally. When it does start, everything is fine. Any ideas? thx, Mark

Do you see the boot up screen 'CMOS' when starting up?If so then I assume you see the screen when you enter login information. ( if not then I assume you see the windows logo )During boot up press the F8 key and boot to safe mode.If you can see the screen then you probably have a video driver issue.Remove and reinstall your video drivers.If you can't see the CMOS screen then remove and reinstall you video card.If you still have these issues then you may have a failing video card or motherboard.

Make sure you have the most up-to-date release for your BIOS, starting with official releases first. If that doesn't fix the problem, try the latest beta release. Beyond that you likely need to play with your system voltages since you're over-clocking. Upping vcore a notch wouldn't hurt (unless you already have it set to some high number to achieve 3GHz).

Check connections and if you can try another monitor.

Thx guys, I think the problem has manifested itself more clearly. When I turned on the PC tonight, the power supply turned on momentarily and then turned off. After that, nada, no juice at all. So, I think my problem before was one the rails playing up and not powering up the video card, prior to causing the power supply fuse to blow. So, its back to overclockers for a replacement under warranty.This brings me to a second point> I built this PC just over a year ago, using the best and most expensive components I could. In that year, I have had fail :1 velociraptor hard drive, 1 Nvidia GTX275 video card & now 1 Tagan TZ1100 PSU. Luckily all replaced under warranty, but still.. That is pretty crap really, probably 25% of my PC components have failed within a year and they were the best I could buy at the time. What does that tell you about quality nowadays.Either I am just unlucky, or component manufacturers are taking us for a ride....Has anyone else had similar experience? Incidentally, the graphics card was the third card I have had fail, I usually upgrade after approx 1 year. thx, Mark

I'm thinking your bad PSU may be the cause of some of the other failures...a skunky power supply can wreak all sorts of havoc.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

YUp, I have to ditto Bob on that one. A bad PSU can cause a whole lot of misery. The lucky ones just blow up right away and you get a neew one otherwise it can be like chasing ghosts unless you know how to check the voltages properly.I almost always keep a spare PSU around and at the first sign of an unexplained problem, will plug it into the system and see what happens.Vic
