The day before last my Compaq wouldn't boot up :( After much troubleshooting I believe I have found the problem; a dead graphics card.
I put the graphics card from my DELL into the Compaq and it did actually boot up (albeit with a terrible display resolution). So I'm fairly confident that all I need is a new graphics card.
If I do need to buy one, I want to buy a good one. I was thinking of the GeForce 8800GT 512MB or the Radeon HD3870 512MB. The thing is, I'm not sure if the power supply in the Compaq can handle these. The current power supply is a 300W one (300W MAX according to the sticker).
So, if I need to buy a PS, what kind of Watts should I be looking at? Bear in mind that at some point in the future I'd possibly like to have more than one graphics card in the Compaq.
Also, if a get a more powerful PS, will my motherboard be able to handle it? According to EVEREST Home Edition System Report my current mobo is as follows:
Motherboard Name: Unknown
Motherboard Chipset: ATI Radeon Xpress 200
Any and all advice is welcome and much appreciated :)
