Hello all

My config is :
Intel Q6600 2.4Ghz
Intel DH33BU board
4GB DDR RAM
Kingston 200 V+ 64GB SSD
LG DVDRW
Cooler Master 350W PSU

As usual I left my Win7 SP1 PC on last night and retired for the day. Next morning, I moved the mouse / pressed a key on the keyboard to start using it and I noticed the monitor refuses to come out of sleep. I tried clicking the mouse/ some keyboard keys and the monitor light was still amber. I switched off the power of the motherboard/cabinet and powered the computer ON. Still same problem. Nothing is happening. The fan on the PSU is working. CPU fan is working. DVDRW is working. My external hard drive is getting powered. Power on Indicator on the motherboard and the front panel of the cabinet is lighting up. The display is not getting a signal. I thought it was some problem with the monitor and connected my other monitor to it but the problem persists.

I suspect the PSU has gone bad. I don't have a spare PSU to check. Can the PSU go bad yet power some devices after being turned on. ?

Hi.

Did you try turning the monitor off and then on? Try disconnecting it from its port and reconnecting it?

When you say you switched off the power, did you then pull the actual plug from the wall?

Might you have another screen you can try to hook up? (Sorry, just now see you did try to hook another up.)

This doesn't sound like yr PSU to me.

Does that board normally have a POST for beep? And if so, do you hear it?

I don't see a video card listed. What do you have?

Are you seeing any hard drive activity?

Yes did all this. Nothing worked. No POST beeps. SSD was powering up but no activity. Turned off monitor and then on. I power off by usually turning off the power switch at the back of the PSU and remove the power cable for 30 secs or so before reconnecting it. Hooked with another monitor also and nothing came up.

Update:

Found out the issue. No idea why what happened happened. I remove one of the RAM sticks and suprisingly the PC was turning on as usual. I then placed the RAM stick I removed in another DIMM slot and the PC is booting fine.

Anybody knows why this happened? I for sure no nothing was touched/moved before this problem happened.

OMG! I posted, may sound strange, but try to reseat yr ram!

Yay!

Congrats, end of stress.:cool:

I had an instinct, sometimes RAM does funny things. Slots too. Gremlins.

You mean Q6600 processor? Its the Intel Quad Core Processor Q6600.

BTW I think the writing was on the wall. Was going nuts over the last 10 days on why my system became suddenly laggy. All I was doing in the last 4-5 days were clean installs and yet the PC lacked fluidity and was generally laggy while browsing the file system and explorer.

Yes, I never heard of that chip until I delved. Not new, but everyone still exulting over it, including gamers.

Is system still laggy now?

If so, is it infection free and cleansed of junk?

If still laggy, you might try and run memtest.

Unless, I mean, the reseating of the sticks stopped the laggy.

I had that happen with a P4 rig with an, I think, 865G chipset, and some DDR (1) RAM.

The house was near some train tracks, and I think that the vibration eventually shook the RAM slightly loose. Happened a couple of times. Or perhaps, the mobo was just going.

I call stuff like that the "TLC fix". Sometimes computers just want some TLC, some attention, and then they're fine again.
