Strange issue with restarting

Hi guys,

I'm having a slight issue with my PC at the moment. I sometimes click restart or let a program restart the PC, it shuts down but then as it restarts it doesn't show the bios screen, nor does it make the beep. The screen says black but the power button is glowing blue. I end up having to press the power button to switch it off and then press it again to start it again (sometimes it just goes to a black screen and doesn't show the bios screen). Sometimes this doesn't work, so I end up pressing the power button to switch it off and then switch it off on the wall and switch it on again then press the power button and then it starts fine.

Any ideas on how to troubleshoot this / fix it?

My PC Specs are below.

Cheers,

Ross

Oh damn. Is it easy to change a power supply? Also how would I know if a new power supply had the correct connections (sorry if that is a stupid question, but when it comes to changing things, the only thing I can changes is HDD's, Ram and GFX cards).

Really? I was told it is a matter of disconnecting everything from the case ha ha. Could you recommend a power supply?

I have to power:

Foxconn G33MO2
Core 2 Quad 2.4 Q6600
2 x HDD's
2 x DVD drives
Memory Card Reader
Sapphire ATI Radeon HD3650 512mb DDR3
8GB Samsung Ram

and I have been told it has to be a "standard ATX" power supply (I don't even know what connectors I need tbh haha).

I would say you need to have at least 650watt power supply. It is shouldn't be too hard to do, because most connections are labelled nowadays.

Documentation

It looks like a standard ATX12V supply. The Dell support site shows you the available connectors. (For your motherboard, it looks like you need a 24 pin ATX power connector, plus a 4 pin 12V. Those are common.)

I'm not sure what to recommend for a PSU. The calculator at www.newegg.com
offers numbers that strike me as ridiculous, but they may be biased towards cheap PSUs (which list high power numbers).

Here's one that's not cheap:

Newegg.com - CORSAIR CMPSU-650TX 650W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply - Power Supplies

(650W Corsair, single 12V rail.)

Thanks for the response. I think I will downgrade to my old GFX card until I can get a new PSU (a 3650 HD 256mb). I've had a look for that on ebuyer.com (as I am in the UK) and the nearest to that I could find is this: Corsair 650W TX Series PSU - 120mm Fan, 80+% Efficiency, Single +12V Rail - Ebuyer is it the same?
