Hello, I haven't been able to play call of duty and i replaced my graphics card thinking it would solve the problem. I went out and bought an ATI raedon 5850 and when i installed it as soon as i turned my computer on it starting squealing and making high pitched noises. people are saying its because of my psu but i dont think it is because i replaced my 450w with a Thermaltake blue evo gaming 650w. here are my specs.
Operating System: Windows XP Professional (5.1, Build 2600) Service Pack 3 (2600.xpsp_sp3_gdr.100216-1514)
Language: English (Regional Setting: English)
System Manufacturer: Custom
System Model: P5Q-PRO
BIOS: BIOS Date: 06/12/08 01:01:23 Ver: 08.00.14
Processor: Intel(R) Core(TM)2 Duo CPU E7200 @ 2.53GHz (2 CPUs)
Memory: 3326MB RAM
And i have a 4850 installed atm, thanks in advanced.
I don't really like Thermaltake PSUs, the only decent Termaltake PSUs that I can think of are W0057 and PurePower 500W.
So it could very well be your PSU. It is deffinitely sounds like a power problem. As he said did you plug in all the cables into the card? You have 48A on the 12v Rail, which is more then enough for the 5850, that requires 40.
If you just purchased the PSU it could be just be faulty.
