Here's my system:


Case: COOLERMASTER CENTURION |CAC-T05-WW BK/SL RT
MB: BIOSTAR TForce965PT 775
Video Card:VGA XFX PVT71PUDP3 7900GS 256MB R
PSU: FSP|AX450-PN 450W RTL
CPU: INTEL|C2D E6300 1.86G 775 2M R
MEM: 1G|G.SK 240P F2-6400CL5S-1GBNQ
HD SEAGATE 250G|ST 7K 16M SATA2 ST3250620AS
DVD_BURN NEC|7170A-0B RAM BK %

I've powered up twice and everything seems to be working inside the case. The case fans, the cpu fan and the video card fan are all working. However my monitor, a ViewSonic DX922 shows no signal. I haven't heard any beeps from the motherboard. Any suggestions as to what I should do?

You need 1 short beep on startup.

Strip it back to mobo, CPU, PSU and start again. You should get a few beeps which indicates memory. Put the sticks in, restart, see if you can get 1 beep.

If OK, add bits one at a time, restarting every time to check 1 beep.

Good Luck :D

OK I stripped it down to the mobo, CPU and PSU and I got no beeps on startup. What now?

I take it the video card is PCI-e?

I would pull the card out and reinstall it and make sure it's firmly seated in the mobo... with the little clip latched.

Also some Pci-e video cards require power plugged into the card. If yours does make sure you have that hooked up.

That's provided the mobo is posting.

The mobo is not posting. Very concerned at the moment...

Is the heatsink fitted properly, with paste applied sparingly?

Does fan spin? Any mobo light on?

I opted to use the thermal interface material that came with the Intel heatsink fan. The fan spins and there the two LED lights on the mobo come on.

So clearly the motherboard is receiving power as in addition to what was stated above I've been able to power a keyboard (the light came on). Could the CPU be the problem? Should I reseat it? Thanks.
