Hi there! I'm new to the forum so please forgive any mistakes I might make!
This is a little bit long winded but I'll keep it as brief as I can.
We bought a Intel CPU Core 2 Quad Q8300 Quad Core 2.50GHz 4M Cache 1333MHz LGA775 from an online store around 15 months ago. We put it together with all the parts we had and we had no graphical input come up on the screen. At that time, we figured our graphics card was outdated (It was a X1600 by ATi) and as the motherboard (An Asus P5QL Pro) had no on-board graphics, we thought to try a newer graphics card.
We tried it with an nVidia 8800GT, only replacing the graphics card in the set-up, and there was no graphics still.
So, we left it for a while, disappointed to say the least but we had no funds to buy another motherboard, which we thought was the issue. We since had a power failure with the older system, but the Q8300 was just left in the P5QL Pro motherboard, untouched.
Last week I finally decided I wanted a whole new system, but to use our Core 2 Quad with it.
We just plugged everything in over the course of today, including a new heat sink for the Q8300. Bearing in mind, in the system mentioned below, the only part that wasn't new (although unused) is the Q8300.
CPU: Intel CPU Core 2 Quad Q8300
HDD: Western Digital 500GB hard disk drive SATA II 300 7200rpm 16MB
RAM: Corsair memory DDR3 1333MHz 4GB kit of 2x240 pin
Heat Sink: Arctic Cooling Freezer 7 Pro Rev 2 Fan Intel Socket 1366 1156 775
Motherboard: Gigabyte motherboard GA-G41M-COMBO LGA775 DDR2 DDR3 mATX
Case: Coolermaster Case Elite 430
GPU: Asus GeForce GT440 1GB GDDR5
PSU: Corsair PSU 750W CMPSU-750TX
I have tried two different monitors. The first one is a Philips 17" screen that acknowledges it's plugged into something, but says 'No graphical input'. The second is a Wacom Cintiq 21UX (2010 edition) which also says no graphical input.
We plugged both monitors, using a VGA cable and a DVI cable, into both the onboard D-Sub and the GPU's D-Sub and DVI sockets. Still nothing.
As the only item which has been carried over, I am guessing the problem part is the CPU.
We are considering contacting for a repair for the CPU, but in the mean time, I was considering purchasing another Q8300 or the Q8400 (we need a 775 socket and I really want a good cpu - so I only have two options for Core 2 Quad. I'd buy an i7 but I have this motherboard now).
Could I ask, do you people think that it's the processor that's the issue, and is it a heard-before problem? Also the fact I need to have one within a couple of days (I'm starting my final degree animation next week and my laptop cant run my Photoshop CS4!! Hence me treating myself!) and cant wait around for this one to be repaired - is it worth buying another one? (My boyfriend needs a processor, too, to update his old PC, so it would go to use should it come back repaired)
Thanks in advance!
