One of my machines has developed a problem, I have tried everything I can think of but no joy.

It seems to power up OK, all fans run, it is an ASUS P5VD2-X MB and has a blue LED on standby and a red when powered up, both work, but there is no output on the monitor. I have tried a different monitor and a different graphics card (there are no on board graphics). Still nothing. I have unplugged all HDD's still no BIOS message.

Anyone think of any thing I haven't tried

Did you try to clear the CMOS with the CLRTC jumper (close to the battery)?
Does it beep when you remove the memory module(s)?
Did you try to refit the CPU?

Cleared the CMOS as per manual, no difference.
No beep with memory removed.
Don't have any paste to refit the CPU but from all tests so far sound like a dead CPU/MB.

Try a different PSU,

Would do if I had one.

For testing purposes you don't need fresh paste.
You can remove the CPU and listen for beeps.
If it beeps, refit the CPU (and cooler) and test it.
If it works, get some fresh paste next monday :)
If it doesn't, and the PSU looks OK get a new mainboard :(

I have a PSU tester in my computer-first-aid-kit :)
It's only $14,99 (free shipping worldwide)

With no (or a bad) CPU nothing will happen - no beep, no POST starting.
Regardless of what else is missing/may be bad.

If CPU in and good, you will get beeps if memory not detected (or not correctly seated, or bad) or video card memory bad (or card improperly seated).

If you are sure your CPU is ok, and fans spin up, but no beeps, most likely a PSU problem like I had this week with a new video card. My system could boot (just barely, apparently), with old card; when I upgraded, the PSU was not strong enough, and stuff spun up, but no beep, no nothing.

As far as paste is concerned, you can use a very small amount of petroleum jelly (Vaseline). It works quite well (fills the air spaces, doesn't dry up, and is easy to clean up). I use it instead of all those fancy (EXPENSIVE) pastes they sell you on all my machines, including my 2 24/7/365 crunchers, with no bad effects. They MAY run 1 or 2 degrees warmer than on Arctic Silver 69, or whatever number they're up to now, but it ain't worth the price or the aggravation, if you have to clean it up. (See www.dansdata.com/goop.htm - it's old, but still valid. And cool).

Good luck!

You could check the health of non solid-state capacitors near the CPU socket. Those 9 solid-state ones should be fine, but the other 5 or 6 near I/O panel are worth checkin'.

Delete, then reload the video driver.

It's whacked.

May want to read that again, the computer won't boot. Hows he going to do that?! It sounds like a power supply issue, more than likely the rail has went out on it. Hit up a local shop and find a psu tester, if it isn't the psu then you got a bad board.

Mobo and power supply must be 3-4 years old, both brought together when I built the machine.

Think I might need a rebuild.

RMA the Board.

Had 4 Weeks ago the same with my EVGA X58 3 SLI. No Post whaterver i changed.

RMA a 4 year old Mobo?

Well, Asus gives 3 Years Warranty. Maybe the Mobo is a little bit younger. :D

It depends on the Serial Number...

I think I will start over,new MOBO,Processor and power supply.

Now just to work out what to get. Any suggestions for around £200 ($316).

This machine has a GeForce 8800 GTS if it's still working! 3299818

For that kind of money you will probably be looking at an AMD AM2 or Intel 775 system. I would suggest looking into an AMD Athlon II X4 and a nice Asus/Gigabyte board. Should serve you well. Anything in the 1155/1156/1366 is going to cost you your budget in cpu alone, and anything quad core in the 775 worth having will be upwards of $270-300 alone.

I would replace 1 part at a time. Start with the Mobo. then the PSU and if all else fails the CPU

I see what you are saying, but you are going to end up costing yourself more time and money in the long run to fix your issue. I would suggest simply ordering yourself a $15 psu tester. Test your psu, if that's the issue then buy a new one and your happy and running again and haven't already bought a motherboard that you didn't need. Then if your psu turns out ok, replace the motherboard, yeah you've spent $15 you could have not spent however you have a nice piece of troubleshooting hardware you can use again and you're back up and running.

Is your motherboard giving you any kind of error code beeps or anything? If not more than likely it's not a ram or cpu issue. If it is giving you codes look them up on the manufacturers website and decide which move you need to make. (Surely with you being a Seti guy you have a friend who will let you at least lift their psu for a little bit to test with?!)
